CHRIST IS AMONG US.

The Celebration of the Holy Mysteries and Other Liturgical Rites:
Mystagogical and Pastoral Guidelines

Introduction

1. God does not remain distant and inaccessible. On the contrary, through his deeds and words he reveals and fulfills the plan of salvation, seeking to bring the human person into communion with him. This salvation is accomplished not in an abstract spirituality detached from life, but in the concrete reality of the Church, above all in her worship, where the proclaimed Word and the enacted rite become «signs of grace.» Instituted by Christ, the Holy Mysteries are actions that embody the experience of the mystery of salvation through perceptible signs and thereby make possible our participation in divine life. They are the «mighty works of God» (cf. Ps 92:6) in the New and Eternal Covenant, powers flowing from the Body of Christ, and actions of the Holy Spirit, who works in his Body, the Church.

2. The Church’s teaching on the Holy Mysteries is not a theoretical system of doctrine. It expresses the living experience of communion with the risen Christ, who continues to act in his Church through the power of the Holy Spirit. Through the centuries, this experience continues in the Church’s liturgy, the sacred worship that is not limited to the Eucharistic Divine Liturgy, but also embraces the Holy Mysteries, consecrations and blessings, and the services of the daily cycle, into which the hymnographic texts of the yearly and weekly cycles are woven. The Church’s teaching on the Mysteries and other liturgical rites is not a speculative system accessible only to highly specialized experts. It is a precious inheritance for every Christian. It invites each person to take part in the mystery of salvation, to deepen faith, and to bear witness to Christ’s victory over sin and death. The Byzantine tradition of the Mysteries, handed down to us through the centuries, is not a frozen form, but a living source that continually flows and gives life to all who desire to drink from it. Our task is to preserve this Tradition and pass it to future generations in all its beauty, depth, and life-giving power.

3. Sadly, we must acknowledge that the Holy Mysteries and other liturgical rites are not always celebrated with full fidelity to Apostolic Tradition and to the prescriptions of the Church’s typikon and the liturgical rubrics contained in the liturgical books. At times, clergy, guided by pastoral motives, try to adapt traditional sacred texts and actions to various situations, hoping such changes will make the rites more practical and understandable. Sometimes this occurs through misunderstanding or an excessive desire to adapt worship to modern times. Yet subjective departures and a will to manipulate often stand behind this, while gaps in a cleric’s formation also become clear. Such unauthorized changes often reveal an inadequate understanding of the very nature of symbolic action, which is an integral part of a Mystery and a liturgical rite. They can distance the faithful from Apostolic Tradition and obscure the grace-filled action of the Holy Spirit. Sometimes this leads to the loss of a proper experience of the Paschal Mystery through participation in a liturgical rite celebrated according to the «Tradition that comes from the apostles and is preserved in the Churches through the succession of presbyters» [1].

4. The task of bishops and clergy is to ensure that the Church’s liturgical life is celebrated according to her Tradition. This is not formalism, but fidelity to the living action of the Holy Spirit, who guides the Church through the ages. It is therefore important to stress the main elements of Apostolic and Patristic Tradition reflected in the richness of the liturgical experience of the Ukrainian Greek Catholic Church, as heir to the Byzantine ecclesial inheritance that comes from the apostles through the Fathers and belongs to the entire Church of Christ [2].

5. Fidelity to Tradition in celebrating the Mysteries and other liturgical rites is not formalism or a fussy attachment to ancient customs. It is an expression of trust in the unchanging action of the Spirit, who teaches all things and brings all things to remembrance (cf. Jn 14:26). In his farewell discourse, Christ promises the apostles the Holy Spirit, who, while preserving the memory of his words and deeds, will continually make present his mystery of salvation, making it real and effective for every generation of the faithful. For this reason, liturgical tradition is not a dead letter, but the living memory of the Spirit acting in the Church.

6. These mystagogical and pastoral guidelines were prepared by the Theological Department of the Patriarchal Curia of the Ukrainian Greek Catholic Church, with the blessing of the Head and Father of the UGCC. They also respond to the call of the Roman Apostolic See to adapt the general principles concerning the validity and proper celebration of the Holy Mysteries, using the theological terms proper to the UGCC and taking account of its tradition [3]. They are addressed to all the faithful of the UGCC, especially the clergy who celebrate the Holy Mysteries and other liturgical rites. Their purpose is not to introduce new rules or complicate current liturgical discipline. Rather, they recall the theological foundations, spiritual meaning, and mystagogical dimension of the Byzantine sacramental tradition. The faithful, reverent, and responsible celebration of the Mysteries and other liturgical rites expresses obedience to the Church. It consists in observing the order set forth in liturgical texts approved by the competent ecclesial authority. These guidelines seek to foster not only careful observance of liturgical rules, but also a deeper experience of liturgical rites. They help readers see the inner theological logic behind these rules. Through this logic, discipline ceases to be an external duty and becomes a conscious, free, and joyful expression of the Church’s faith. In worship, the Church lives, prays, and reveals Christ’s saving presence to the world.

The Mystagogy of the Holy Mysteries

7. For the Christian East and West, the principle «the law of prayer is the law of belief» (Lat. lex orandi, lex credendi) [4] is fundamental. It expresses the inseparable bond between liturgical prayer and the faith of the Church. Saint Epiphanius of Cyprus sees the Church as the guardian of the apostolic faith, which is proclaimed in the Creed and lives in worship, the Holy Mysteries, and Apostolic Tradition [5]. Thus, the truth of faith is preserved and handed on not only through theological treatises, but first of all through the living experience of the praying Church. For this reason, the Patristic tradition joined theology inseparably with prayer. A clear witness is the well-known saying of Evagrius Ponticus: «If you are a theologian, you will pray truly; and if you pray truly, you are a theologian» (Gr. Εἰ θεολόγος εἶ, προσεύξῃ ἀληθῶς· καὶ εἰ ἀληθῶς προσεύξῃ, θεολόγος εἶ) [6]. For the Fathers of the Church, theology was not only the intellectual study of the truths of faith. It was also the fruit of a living experience of communion with God in prayer. Yet this experience does not exclude rational reflection. What is experienced in prayer must be considered by academic theology, which can unfold, explain, and organize the Church’s prayerful insight. Theological works arising in academic settings find their fullness and their test within liturgical prayer. Thus, liturgical and academic theology do not compete or oppose each other, but enrich each other. Worship becomes a source of theology, and theology becomes a word the Church offers before God in prayer. In this sense, the liturgical rite is not only a subject of theological reflection, but also its living source. In it, the Church prays, professes her faith, and enters the mystery of God’s presence.

8. The Church’s liturgy does not divide word and action into separate, unrelated parts. It joins them naturally in one sacramental act. This union reveals a deep truth. In the liturgical rite, the past is not simply recalled and teaching is not merely proclaimed. Here, Christ’s Paschal Mystery, his death and resurrection, becomes the experience of a living meeting with the Lord today. As the Fathers of the Church aptly state, the invisible is communicated through visible symbols [7]. This basic principle of Patristic sacramental theology reveals the heart of the Byzantine understanding of symbol, which differs greatly from the word’s common modern use. A symbol is not only an external sign pointing to something absent, but also a real means of conveying the divine presence. A symbol is always ontological. It signifies and at the same time brings about what it symbolizes. The waters of Baptism do not merely remind us of cleansing. They truly cleanse. The Eucharistic bread and wine do not merely symbolize the Body and Blood of Christ. They truly become his Body and Blood.

9. Byzantine theology places special stress on the mystagogical dimension of the Mysteries. Mystagogy (Gr. μυσταγωγία) is more than teaching about the Mysteries as external rites or giving a theoretical account of their meaning. It is a gradual initiation into their depth, a process lasting throughout a person’s life. In this setting, mystagogy is not only a theoretical explanation of rites or historical facts about their origin. It is also a gradual entry into the experience of the Mysteries, which helps us see the invisible through the visible. In the end, the texts and the very course of worship are themselves mystagogy.

10. In his treatise The Ecclesiastical Hierarchy, Pseudo-Dionysius the Areopagite teaches that God carries out his deifying actions (Gr. θεουργικαὶ ἐνέργειαι) through sacred hierarchical rites, cleansing, enlightening, and deifying the human person [8]. In the Mysteries, the active power is not a created force, human faith, or ecclesial tradition by itself. It is divine power, which transforms the human person in spiritual growth from the image to the likeness of God. The energies are God’s way of acting in the world. They are his living powers, through which he remains close to creation without ceasing to transcend it. Through the words, symbols, and sacred actions of the Mysteries and the Church’s whole liturgical life, the human person shares in God’s real presence. Worship is the place of a living encounter with God, who acts, sanctifies, and transforms his faithful.

11. The Mysteries, which the Church received from Christ and celebrates through the power of the Holy Spirit, reveal God’s grace acting in visible signs. Yet ecclesial tradition goes beyond a merely useful view of the Mysteries as «means of grace.» They are not simply «rites» performed to obtain spiritual goods. They are living meetings with the risen Christ and the experience of salvation, through which believers become «partakers of the divine nature» (Gr. θείας κοινωνοὶ φύσεως; cf. 2 Pt 1:4) in the Church as the Body of Christ. Pope Saint Leo the Great writes, «What was visible in our Redeemer has passed into the Mysteries» [9]. Saint John Damascene develops this thought by pointing to the New Testament understanding of the Christological foundation of all sacramental life. What took place in Christ through his incarnation, earthly life, death, and resurrection becomes available to every believer in every age through the Mysteries [10]. The Mysteries are not simply a remembrance of past events, but their living presence today. The Church celebrates the Mysteries as the source and summit of her life, because through them the faithful become partakers of the Savior’s Paschal Mystery. They are the source of the Church’s life, because through them she is constantly born anew from the side of the crucified and risen Christ. They are also the summit of this life, because in them the fullest union with God possible in earthly life is attained.

The Church as the Primary Mystery

12. Patristic Tradition stresses a basic truth. The Church herself is a Mystery, an «image of the Most Holy Trinity» and the great Mystery of Christ’s presence in the world. Saint John Chrysostom teaches that, as Eve was formed from Adam’s side, so the Church is born from the pierced side of the new Adam, Christ, from which blood and water flowed (cf. Jn 19:34) [11]. Saint Augustine writes, «Eve was formed from the side of the sleeping Adam; the Church was formed from the side of the suffering Christ» [12]. This is not merely an allegorical reading, but a revelation of the ontological bond between Christ’s sacrifice and the Church’s life. In this Gospel event, the Church sees not only a historical fact, but a deep theological truth. All sacramental life flows from Christ’s sacrifice on the cross, and through it the faithful receive salvation and sanctification. The Savior’s pierced side becomes the source of grace that flows to humanity through the Church’s Mysteries. Blood and water flowed from the wound in the crucified Lord’s side, symbols of the Mysteries that nourish the Church. As the troparion sings, «Come, let us drink a new drink, not miraculously drawn from a barren rock, but from the fountain of incorruption springing from the tomb of Christ; in him we are established» [13].

13. The Catechism of the UGCC, Christ Our Pascha, teaches: «Christ continues to teach, heal, forgive, and give life in the Church. Therefore, the Church is the Mystery of his presence and the meeting place of God and the human person» [14]. This takes place through the Holy Mysteries, in which the sacramental nature of the Church as the Body of Christ becomes present and active. This typology shows that the Church is not simply an external institution created to organize religious life. She is the organic Body of Christ and lives his life. From this follows an important conclusion. All the Mysteries and other liturgical rites are expressions of this organic life, not external rites that may be performed mechanically or formally.

14. Saint Irenaeus of Lyons teaches: «For where the Church is, there is the Spirit of God; and where the Spirit of God is, there is the Church and every grace; and the Spirit is truth» [15]. Saint Maximus the Confessor develops this deep ecclesiological vision, which has important results for understanding the Church’s life. According to him, the Church is an image of the unity of the Holy Trinity. As in the Trinity, unity is achieved through love without the loss of diversity [16]. The Church is not simply an external group of people joined by shared religious beliefs or rites. She is a living reality that reflects the inner life of God himself. In the Trinity, the three Persons remain in perfect unity of love without merging into one person or separating into three gods. In the same way, the Church is called to be a place of such unity between human persons and God. It is unity in diversity, where each person keeps a unique identity while living in perfect love with others.

The Mysteries as Participation in the New Life in Christ

15. Starting from the understanding of the Church as the mystical Body of Christ, Byzantine theology stresses that the Mysteries are not only symbols or signs of invisible realities. They are participation in the new life itself. Through the Mysteries, Christ acts in his Church by the power of the Holy Spirit and transforms the lives of the faithful into communion with God. This transformation is not an external rule or moral duty that a person must fulfill through personal effort. It is an ontological change. The Mysteries form the Body of Christ and make the faithful a «royal priesthood» (Gr. βασίλειον ἱεράτευμα; 1 Pt 2:9). This New Testament phrase from the First Letter of Peter reveals the twofold dignity a Christian receives through the Mysteries. The Christian becomes a «king,» having power over sin and death through participation in Christ’s victory over these forces of evil. The Christian also becomes a «priest,» able to offer spiritual sacrifices and serve as a mediator between God and the world. This is not a metaphor or an honorary title, but a real participation in Christ’s own priestly ministry. The Mysteries are not only means for receiving «grace.» They bring us into his way of being [17]. From this comes a dynamic understanding of grace. It is not a «thing» that can be gained and lost like a material object. It is a way of life and participation in God’s own being.

16. The deepest mark of the Byzantine understanding of the Mysteries is their Paschal dimension. In the Mysteries, the Church does not simply remember or celebrate Christ’s Pascha as a past event. Each time, she experiences it as a living and present reality. The Paschal view is not an added part of the understanding of the Mysteries. It is their inner principle and the key to their deepest nature. Christ’s Pascha, his suffering, death, resurrection, and ascension, is the central event of Christian history. At the same time, it is an ever-present reality made present in every sacramental action.

17. The Eucharist makes present the whole fullness of Christ’s Paschal Mystery, his suffering and death, and also his glorious second coming. It is an eschatological banquet, a foretaste of the heavenly feast, and participation in the eternal joy of God’s Kingdom. Through the Eucharist, we become partakers of his Body and Blood in the fullest sense, not only spiritually or symbolically, but also substantially. In Baptism, we become members of the Church and heirs of the new life in Christ, while also being «buried with him.» This means not a symbolic likeness, but real participation in his death, which frees us from slavery to sin. Immersion in water symbolizes entry into the Lord’s tomb, where all that belongs to fallen human nature dies: sin, mortality, and separation from God. Rising from the water symbolizes resurrection with Christ and birth into a new way of being, marked by communion with him, victory over death, and participation in divine life. Chrismation is participation in his Paschal anointing with the Holy Spirit. As Jesus was anointed by the Spirit after his baptism, and especially after his resurrection, so through Chrismation the Christian shares this divine anointing and receives a share in Christ’s prophetic, priestly, and royal ministry [18]. Through Chrismation, we become «anointed ones» (Gr. χριστοί), literally little «christs» [19], sharing the same anointing with the Holy Spirit that Jesus possessed at his baptism and transfiguration. Repentance is an experience of the Paschal victory over sin and death. Each Confession is a new resurrection, a return from spiritual death to life and from separation to reconciliation with God. It is not merely legal forgiveness, but an ontological restoration and a renewal of Paschal joy. Holy Orders is participation in Christ’s Paschal high priesthood, which he fulfilled through his death and resurrection. The cleric becomes not merely an officer of a religious group, but an iconic representative of Christ the High Priest, who offered himself for the salvation of the world and now continues this ministry through his Church. Marriage between a man and a woman is an image of Christ’s Paschal love for the Church, a love revealed in his sacrificial death and resurrection. As Christ gave himself for the Church to sanctify and glorify her, so the spouses are called to mutual self-giving and sacrificial love that transforms and sanctifies. Holy Anointing is participation in Christ’s Paschal victory over illness, suffering, and death. Through anointing with holy oil, the sick person is united with the suffering and risen Lord and receives strength to endure illness. If helpful for salvation, the person also receives healing or a grace-filled preparation for the passage into eternity.

18. Thus, the history of the Incarnation is not merely remembered or symbolized in the Mysteries. It truly continues, and each sacramental action is a living presence of salvation in the present. What Christ accomplished once in a specific moment of history becomes present through the Mysteries for every generation. It continues to act beyond the limits of time and space. Each Mystery is a new way of experiencing the Paschal Mystery and a new entry into the eternal act of love that Christ accomplished once in history and that continues in all its fullness in the life of the Church.

19. This ontological view means that the Mysteries do not simply affect a person from outside. They change that person’s very nature and lead to divinization (Gr. θέωσις), participation in the life of God. Pseudo-Dionysius the Areopagite teaches that God is at once wholly beyond being (Gr. ὑπερούσιος) and present in the world through his grace-filled «processions» (Gr. πρόοδοι) and providential actions (Gr. πρόνοιαι). Through these divine manifestations, the human person shares in God’s life, especially in the Church’s sacred rites. The «names» of God (Gr. ὀνόματα), Life, Light, Love, and Goodness, do not reveal his essence, which remains inaccessible. They point to his grace-filled actions and gifts, through which he deifies creation without erasing the difference between Creator and creature [20]. This distinction answers an ancient theological question. How can the human person become «god by grace» without harming God’s transcendence or being absorbed into him? In his transcendence and superessentiality (Gr. ὑπερουσιότης), God remains wholly beyond reach. Yet through his theophanic manifestations, he makes himself accessible for the divinization of the human person. Each Mystery becomes a pledge of divinization, which will reach its fullness in the eschatological Kingdom and is already given as the first fruits of transformed creation.

20. The Church’s Mysteries are not only acts of sanctification here and now. They are also a promise of the coming Kingdom and a foretaste of what God prepared from all ages. In each Mystery, the faithful receive a share in the new life that will be fully revealed only at the end of time, when «God will be all in all» (1 Cor 15:28). Baptism begins this new being. The Eucharist gives an experience of the heavenly banquet. The Mystery of Marriage becomes an image of the wedding joy that will fill the union of Christ and the Church. Therefore, the Mysteries are not limited to their historical moment. They open the horizon of eternity to the human person. Through them, the Church already lives the reality of the future, and the faithful receive the «pledge of the Spirit» (2 Cor 1:22), who leads them toward final fulfillment in God’s Kingdom. Thus, the Mysteries are not only the holy things of the present life. They are also images of the coming glory, when Christ «will come again in glory to judge the living and the dead» and when the Church enters the eternal Pascha.

A Comprehensive Understanding of Sacramentality

21. The ontological understanding of the Mysteries naturally leads to their broad reading in the Eastern tradition. The number «seven» is not viewed as a strict limit or a mathematical formula, because the whole life of the Church is Mystery [21]. Baptism, Chrismation, Eucharist, Repentance, Marriage, Holy Orders, and Holy Anointing are central, not because other liturgical rites are less important or less «sacramental,» but because they are the clearest expressions of the sacramental nature of the Church’s whole life. The blessing of water at Theophany, monastic tonsure, the funeral service, the blessing of homes, and other sacred rites are also recognized as «signs of grace.» The liturgical year, with its great feasts, fasts, and weekly and daily cycles, is filled with grace-filled actions that lead the human person toward divinization. Each day of the Church calendar reveals new parts of the mystery of salvation and offers new ways to grow in holiness.

22. This understanding has deep theological roots in the thought of Saint Maximus the Confessor, who developed the teaching on the «logoi,» God’s intentions for each thing (Gr. λόγοι τῶν ὄντων). According to this Father of the Church, each thing in creation has its own «logos,» a divine idea that defines its nature and purpose [22]. Therefore, all creation is sacramental in potential, because everything can become a place of meeting with God when used according to its logos, or God’s plan. In the Mysteries, this potential is fulfilled most fully. Material elements, such as water, bread, wine, and oil, are not simply used as helpful symbols. They are transformed and become instruments of God’s grace, revealing the original calling of all matter.

23. Even the simplest daily actions can become a place where the human person meets God and continues the Church’s liturgical life. This happens when they are performed in union with Christ, in a spirit of prayer, thanksgiving, and love. Everything can become sacramental when done with constant remembrance of God and filled with thanksgiving. This does not lessen the importance of the liturgical Mysteries themselves, but shows how they continue throughout life. Baptism does not end when one leaves the church. It must continue each day as «dying to sin.» The Eucharist is not limited to the time of the Divine Liturgy. It must transform all our relations with people and creation. The liturgical calendar gives practical form to this idea of all-embracing sacramentality. The blessing of fruit at Transfiguration, Paschal foods at the Resurrection, and homes at Theophany continue the main Mysteries within the concrete lives of believers. Saint Germanus of Constantinople sees worship as a symbol and a real ontological inclusion of all creation in the work of salvation [23]. No «secular» part of life is wholly separated from the sacred. Everything can and must be sanctified, and everything can become a place of divine manifestation. This does not mean making the world sacred in a pagan sense. It means transforming the world into a temple where everything serves the glory of God.

24. A comprehensive understanding of sacramentality does not mean relativism or subjectivism, because all Mysteries have an objective basis. They belong not to the human person, but to Christ. The Church does not own them, but serves and guards them [24]. This stresses an important truth. The Church does not invent the Mysteries and cannot change them at will or shape them to fit cultural trends. She received them as a priceless gift from Christ himself and is renewed each time they are celebrated.

The Importance of Synergy Between the Human Person and Grace

25. One of the most distinct parts of Byzantine sacramental theology is its stress on the need for synergy, the cooperation of the human person and God (Gr. συνεργία ἀνθρώπου καὶ θεοῦ), or the human will with divine grace. The Mysteries do not work magically, apart from the state of the person receiving them. They are not automatic means of salvation that guarantee a good result without regard for a person’s spiritual state. Divine grace always respects human freedom and never acts against the human will.

26. Receiving the Mysteries requires proper preparation: faith, repentance, inner readiness, and a sincere desire to receive the divine gift. Without these spiritual dispositions, the Mysteries and other liturgical rites may remain without fruit, though their objective validity is not in doubt. For example, Baptism always truly cleanses from ancestral sin and makes a person a member of the Church, apart from that person’s subjective state. Yet the fruits of Baptism, new life in Christ, spiritual growth, and holiness, depend on the person’s later cooperation with grace. Likewise, the Eucharist always truly contains the Body and Blood of Christ, apart from the faith or lack of faith of the person receiving them. Yet for an unbeliever or unrepentant sinner, they may become not a source of life but «judgment and condemnation» [25], a cause of condemnation, as the Apostle Paul warns (1 Cor 11:29).

27. The practical results of the principle of synergy have great importance for pastoral ministry. They reveal the deep theological truth about the cooperation of divine grace and human freedom in spiritual life. This principle calls for proper catechetical preparation before receiving the Mysteries, especially adult Baptism, Holy Communion, and Marriage. A person must knowingly open the heart to divine action, understanding that the Mysteries are not magical acts. They begin a new life in Christ that needs constant cooperation with grace. Regular Confession becomes a special place of synergy. A person recognizes and repents of sins. Through the priest, God gives forgiveness, and the penitent forms a firm purpose of amendment. Spiritual life thus becomes a constant process of cleansing and growth. Spiritual guidance is a school of synergy. The guide helps a person discern the action of God’s grace, learn to respond to it, and overcome barriers to cooperation with God. This changes pastoral ministry from the simple performance of rites into deep spiritual guidance for people on their path to holiness through conscious cooperation with divine grace.

28. At the same time, the principle of synergy does not mean that the fruitfulness of the Mysteries is directly tied to a person’s spiritual efforts or moral perfection. Grace always remains an unearned gift of God’s mercy. It cannot be «earned» through any spiritual exercises or moral achievements, because even the most perfect human righteousness remains inadequate before God’s boundless holiness. This gift requires an active human response, not as a condition for receiving it, but as a condition for receiving it fully and bearing fruit in life. A person’s spiritual efforts, prayer, fasting, repentance, and desire for holiness do not «earn» grace. They open a place in the heart for grace to act, just as a farmer does not create the sun and rain, but prepares the soil for their fruitful work. True cooperation does not make the human person God’s equal partner. It means freely and humbly opening oneself to the action of grace, allowing it to transform one’s whole life, from the deepest motives of the heart to concrete acts in daily life.

The Priest as the Iconic Presence of Christ

29. Understanding the Mysteries as the action of Christ himself through the Church gives basic shape to the Byzantine theological view of priestly ministry. When celebrating the Mysteries, the bishop and priest do not act «from themselves,» relying on their own spiritual power or personal holiness. They serve as living images of Christ, the eternal High Priest, and at the same time «in the name of the Church,» which is the mystical Bride of Christ.

30. Byzantine theology of the priesthood developed a deep and distinct idea of iconic presence (Gr. εἰκονικὴ παρουσία). The priest does not replace Christ in a literal sense and certainly does not become Christ in substance. Yet at the concrete moment of sacramental action, he reveals Christ as a clear and living icon. This difficult reality can be understood through Saint John Damascene’s account of the theological meaning of the icon. A painted icon is not the prototype itself, since Christ is not present in wood and paint. Yet it truly represents the prototype, and through it one can address the prototype and receive grace from the prototype. In the same way, the priest truly represents Christ in the sacramental action while remaining a limited and sinful human being [26].

31. This iconic presence requires special spiritual transparency and self-denial from the priest. His first role is to «make room» for Christ and allow Christ to act fully through him as through an instrument. The less the priest draws attention to his own person, talents, or spiritual achievements, the more brightly Christ’s presence shines through him. This does not deny the priest’s personhood or require its suppression. On the contrary, it means its highest fulfillment in likeness to Christ. The priest becomes so open to Christ’s grace that people see the Lord himself through him. The priest reaches the greatest personal fullness when he most fully disappears as a barrier between Christ and the people.

32. In his treatise The Ecclesiastical Hierarchy, Pseudo-Dionysius the Areopagite develops the idea of priesthood as «divine imitation» [27]. The priest is called to imitate not merely human virtues, but Christ’s own ministry as the Good Shepherd who lays down his life for the sheep. This imitation is shown in readiness for self-sacrifice, care for the spiritual growth of the faithful, defense of the purity of faith, and constant prayer for the flock entrusted to him. The priest becomes an «icon of Christ» not so much through special charismatic gifts or visible holiness, but through fidelity to his call to serve people.

33. This means, among other things, that even the personal unworthiness of the minister cannot block the unchanging action of the Spirit, because Christ himself is the true celebrant of every Mystery and other liturgical rite. This ecclesial belief, formed during the sharp debates with the Donatists in the fourth and fifth centuries, protects the Mysteries from subjectivism and ensures their objective validity. The faithful can be fully certain that in the Mysteries they truly meet the living Christ, apart from the minister’s personal qualities, holiness, or sinfulness. An icon remains an icon even when damaged or darkened with age. In the same way, the priesthood remains valid even in the hands of an unworthy minister, though his unworthiness can hinder the full fruit of the sacramental action.

34. In his treatise On the Priesthood, Saint John Chrysostom stresses that «the priestly ministry is carried out on earth, but according to the order of heaven… . Neither a human being, nor an angel, nor an archangel, nor any other created power, but the Comforter himself established this order» [28]. The priest is only a minister and the visible servant of Christ’s action. He does not celebrate the Mysteries by his own power or personal holiness, but is an instrument of God’s grace. As John Chrysostom teaches, the priest «only lends his tongue and extends his hand,» while Christ himself is the true celebrant of the Mystery [29]. Therefore, the priest is not the author of the prayers or sacred rites he performs. He is called to serve the Church’s liturgical tradition faithfully and responsibly. This understanding differs greatly from modern ideas of creativity as individual self-expression or change for its own sake. In the Church, true creativity does not invent something new, but reveals eternal truths anew. It does not destroy the old, but renews it and makes it present for new generations.

35. Understanding that the priest has no priesthood of his own apart from Christ’s priesthood, but shares in Christ’s ministry, has deep ecclesiological results. The priesthood is not the privilege of certain people or a special state separating them from other Christians. It is a ministry to the whole Church as the Body of Christ. The priest acts not in place of the Church community, but in its name and for its growth in unity. Priestly ministry in the Church consists in sharing the one priesthood of Christ, who is the «High Priest according to the order of Melchizedek» (Heb 7:17). It cannot be reduced to carrying out a function or profession.

The Role of the People of God

36. The word «liturgy» (Gr. λειτουργία) literally means «public work» or «common work.» The Byzantine understanding of liturgical ministry stresses the priest’s service and the active participation of the whole Church community. The Liturgy is not the private prayer of the priest. It is the action of the whole Body of Christ: «For where two or three are gathered in my name, I am there among them» (Mt 18:20). The priest does not celebrate a liturgical rite for himself or for a few random visitors. It assumes a real community that takes part in the sacramental action knowingly and actively. At the same time, this does not mean that the number of those present determines the quality of the liturgical rite. Even when only «two or three» are present, if they are truly gathered «in Christ’s name,» it keeps its fullness and validity.

37. This principle has practical results for the ordering of liturgical life. Even when the priest says the prayers, he does so not as a private person, but in the name of the whole Church. The Liturgy is the common action of all God’s people. It is not the priest’s «private affair,» which others watch in silence. When the people of God sing or respond to the priest’s prayers, this is real participation in the sacramental liturgical rite and the community’s share in the common work of glorifying God and sanctifying the world. Each member of the Church has a distinct ministry. The deacon chants the litanies and serves at the altar. The reader proclaims the biblical readings. The choir sings the liturgical hymns. All the people actively answer «Amen» and «Lord, have mercy,» sing the Creed, and take part in other ways. This conciliar nature also appears in the frequent use of the plural in liturgical texts: «we offer,» «we ask,» and «make us partakers.» In this worship, each person finds a place and a duty. Not all are called to be priests or theologians. All, however, must witness to Christ’s resurrection, carry Paschal joy, and bring divine grace into a world that deeply needs healing and salvation.

38. Clergy and laity, young and old, learned and simple, together form God’s people, the Church of Christ. They are called to guard and hand on faithfully the experience of sacramental life. Theologians, catechists, and spiritual guides have a special call to preserve and pass on the treasures of liturgical worship. They help people understand and experience more deeply what takes place in the Mysteries. They prepare them for conscious and fruitful participation in sacramental life. Christian parents are called to be the first catechists of their children. They pass on not only outward knowledge of the faith, but a living experience of communion with God. The domestic church should continue the worship of the temple. It should be the place where children first experience God’s presence and learn to pray. Liturgical life does not end when people leave the church. It continues in daily life, where every action can become a form of service to God and neighbor.

39. Those who take direct part in liturgical ministries, including readers, cantors, and servers, bear a special duty for the Mysteries and other liturgical rites. They do not simply perform practical tasks. They are fellow participants in the sacramental action, through whom the Holy Spirit works. Their preparation, reverence, and spiritual state affect the whole spirit of worship. Through their responsible service, the Church’s rites become not only beautiful and majestic actions that shape the senses, but also effective means of evangelization and mystagogy.

The Church as Guardian of the Mysteries

40. In the central Eucharistic prayer, the priest solemnly says, «We offer to you yours of your own, on behalf of all and for all» (Gr. Τὰ σὰ ἐκ τῶν σῶν σοὶ προσφέρομεν κατὰ πάντα καὶ διὰ πάντα) [30]. When the people of God pray these words, they do not simply repeat a fixed formula. They proclaim the basic theological truth that everything belongs to God, and that the human person can offer him only what was first received from him as a gift. This ancient liturgical formula reveals a deep paradox and the mystery of the Eucharist. We offer God what belongs to him, bread and wine as fruits of his creation and life as his gift. At the same time, we offer these things «from ourselves,» as the fruit of human work, human effort, and the human response to God’s call. Here the priest expresses the basic synergy of God and the human person, which is the foundation of the Church’s whole sacramental life.

41. «But we have this treasure in clay vessels, so that it may be clear that this surpassing power belongs to God and not to us» (2 Cor 4:7). The contrast used by the Apostle Paul describes well what takes place in the Mysteries and other liturgical rites. The Church is called to guard the riches held within them, so the priority of God’s saving action in history is never obscured. The Church is the servant of the Mysteries, not their master. In celebrating the Mysteries, she receives their grace. By preserving them, she is herself preserved by them. The Church’s authority over the Mysteries is like her authority over Holy Scripture. In the Bible, the Church recognizes the Word of God written under the inspiration of the Holy Spirit and sets the canon of sacred books, while submitting to that Word. In the same way, she discerns the sacred signs through which Christ gives Paschal grace.

42. The unity of word and sign in the Mysteries is not accidental. It reflects the nature of divine Revelation, in which the Word becomes flesh and acts through material signs. Liturgical texts constantly stress that Christ, not a human being, is the true celebrant of every Mystery. Thus, the priest prays solemnly, «O King who loves mankind, come now through the descent of your Holy Spirit and sanctify this water» [31]. These words stress that God, not the human minister, is the true sanctifier of the water and the true baptizer. Liturgical texts stress the Trinitarian structure of every Mystery. They address the Father as the source of every blessing, recall the saving work of the Son, and invoke the Holy Spirit as the power that makes this saving work present. The priest does not act through his own authority or personal holiness. He asks God to act through him as through an instrument.

43. For the validity of every Mystery, the Church has always required both the sacred actions and the words. This requires the careful fulfillment of all liturgical texts and rubrics, including those concerning ceremonies: gestures, blessings, incense, vestments, and other elements found in the liturgical books. Every word and gesture in liturgical rites has been refined by generations of saints and theologians and tested through centuries of ecclesial experience. Unauthorized changes risk erasing this wisdom. The Holy Fathers and Church writers often stress the basic importance of exact observance of the set formulas of the Mysteries, because sacred words and the order of the liturgical rite cannot be changed by human choice. The Fathers of the Second Vatican Council stress: «In virtue of power conceded by the law, the regulation of the liturgy within certain defined limits belongs also to various kinds of competent territorial bodies of bishops legitimately established. Therefore no other person, not even a priest, may add, remove, or change anything in the liturgy on his own authority» [32]. Each word and rite has a precise theological meaning, and divine grace acts through them. Preserving liturgical tradition is not a matter of custom, but a basic principle of fidelity to Apostolic Tradition. This is not conservatism for tradition’s own sake. It is a deep awareness that changing a liturgical gesture or text can change the understanding of the Mystery and the liturgical rite itself.

44. Sacred words and actions have never depended on the will of separate persons or communities. The Church’s duty is not to define these elements at will, but to preserve and hand them on faithfully in obedience to the action of the Holy Spirit. When a priest adds personal comments or changes set formulas to fit his own taste, he risks placing his own person between Christ and the people instead of becoming Christ’s clear icon. From this understanding, it follows that departures from the set order of worship can distort the perception of the Lord’s action and hinder the clarity of the sacramental signs. Adding personal words or changing liturgical signs and gestures can quietly alter the understanding of the Mysteries and weaken the iconic expression of Christ’s presence in sacramental worship. This can happen even when the changes seem small or arise from good intentions. They can place the true gift of sacramental grace at risk and harm the faithful. Any willful change to liturgical forms harms the beauty of the Liturgy and obscures the action of Christ himself.

45. Liturgical discipline is not a limit on creativity, but a condition for the highest creative act: becoming a living icon of God. Liturgical fidelity to the set rite, including exactness in words, gestures, sacred elements, and liturgical vestments, goes far beyond outward form or a fussy concern with details. It is a needed spiritual condition for the minister to become a true icon of Christ.

46. The Church’s true freedom lies in fidelity to Apostolic Tradition. Change for the sake of modernization or adjustment to current trends cannot be her defining aim. The Church guards this Tradition not as a museum object or an item of historical interest, but as the living presence of the Holy Spirit in every age. Saint Vincent of Lérins stated the classic principle for discerning true Tradition from later human additions: «what has been believed everywhere, always, and by all» (Lat. quod ubique, quod semper, quod ab omnibus) [33]. This test of universality, antiquity, and catholicity assumes organic growth within Apostolic Tradition. It excludes both dead stillness and the mechanical repetition of old formulas [34]. A tree grows and changes, putting forth new shoots and leaves, while keeping its roots and original nature. In the same way, liturgical tradition can develop, deepen, and even partly change while keeping its essential identity with the apostolic faith.

47. When the Church creates new liturgical texts, she does not destroy Tradition, but continues it. Any renewal must agree with sound tradition and correspond to it. New elements should not seem foreign or forced into the body of worship. They must grow naturally from existing norms [35]. Thus, new liturgical texts are written in the spirit of ancient models. New melodies are formed from traditional modes. New rites fit within the common structure of worship. This is a living continuation of Tradition and its new embodiment in new historical settings.

48. Living Tradition is always able to grow naturally, adapt with care to new conditions, and answer new challenges. Yet this growth always takes place from within Tradition, in its spirit and according to its logic, not through the outside imposition of foreign elements. Therefore, the Church stresses that her ecclesial inheritance must not be distorted by «favoring ways of thought, spirituality, and devotion that do not agree with their own spiritual heritage» [36]. The Byzantine Ukrainian ritual tradition has its own distinct theological, liturgical, spiritual, and canonical logic. It has a unique way of experiencing and expressing the Christian faith, formed through centuries by the action of the Holy Spirit within concrete historical and cultural conditions.

49. Sadly, foreign influences also appear in the celebration of the Holy Mysteries within the UGCC. Though valuable within another ritual tradition, they disturb the organic unity of the Byzantine Ukrainian liturgical heritage. These influences appear in the use of foreign formulas, changes to the traditional order of ritual actions, the introduction of foreign symbolic elements, and even changes to the theological understanding of the Mysteries themselves. They apply Western scholastic methods in place of the Eastern apophatic and mystical tradition. This situation needs review «in the sense of returning to the ancestral traditions» [37]. This does not mean an archaeological rebuilding of ancient forms. It means restoring the authentic spirit and inner logic of the Byzantine tradition, cleansing it of foreign layers built up over centuries, and opening new paths for organic growth in modern conditions. Such a process requires deep knowledge of one’s own heritage, theological wisdom to discern authentic growth from distortion, and pastoral care for the needs of the faithful today. They have a right to the fullness of their spiritual tradition in its purest and most complete form.

Conclusion

50. The Eastern Christian understanding of the validity of the Holy Mysteries reveals a deep and whole vision of ecclesial life. At its center stands the living presence of the risen Christ, which surpasses human religiosity and ritual practice. The Mysteries are real meetings with God that transform the human person and lead to divinization. They go beyond symbols and pious customs. This tradition shows that the authenticity of the Mysteries depends not on subjective feelings or the personal holiness of those taking part, but on fidelity to Apostolic Tradition and the action of the Holy Spirit, who «teaches and brings all things to remembrance» (Jn 14:26). The Church is their faithful guardian and servant, called to preserve and hand on what she received from Christ through the apostles and Fathers.

51. Priestly ministry is understood as the iconic presence of Christ, who «is always present in his Church, especially in her liturgical celebrations. He is present in the Sacrifice of the Divine Liturgy and in the person of the minister… but most of all under the Eucharistic species. By his power he is present in the Holy Mysteries… . He is present in his word, since it is he himself who speaks when Holy Scripture is read in the Church. Finally, he is present when the Church prays and sings, for he promised: „Where two or three are gathered in my name, I am there among them’ (Mt 18:20)» [38]. This requires special transparency and self-denial from those celebrating the Mysteries and other liturgical rites, so they do not hide Christ but allow him to act through their ministry. Liturgical fidelity is not formalism. It is a spiritual need if the Mysteries and other liturgical rites are to fulfill their role as «signs of grace,» real means of giving divine life to the human person. This fidelity requires a deep understanding of the inner logic of liturgical actions, their theological meaning, and their spiritual effect on the Church’s life. In liturgical tradition, we find not merely a theological system, but the experience of the Church. Through the ages, she preserves and hands on the treasure of the apostolic faith. She helps each new generation of Christians discover the endless riches of life in Christ through the Mysteries and other liturgical rites of his Church. They become partakers of the same divine reality experienced by the apostles, martyrs, confessors, venerable monastics, Holy Fathers, and every generation of the faithful who came before us in faith. In this way, the Church ensures that her experience continues and is handed on to future generations.
