Liturgy as Theology

The principle of lex orandi lex credendi (“the law of prayer is the law of belief”) holds that the Church’s worship is not merely the application of theology but is itself a primary theological source. In the Orthodox tradition, the liturgy is the living locus of dogma – the place where the faith is not only expressed but experienced and transmitted. Fr. Alexander Schmemann (1921–1983) developed this insight into a comprehensive “liturgical theology” that has profoundly shaped modern Orthodox thought across all jurisdictions.

Tradition: Pan-Orthodox

Lex Orandi Lex Credendi

The Principle

The axiom lex orandi lex credendi (more fully, legem credendi lex statuat supplicandi – “let the law of praying establish the law of believing”) originates with Prosper of Aquitaine (c. 390–c. 455), a disciple of Augustine, who invoked the Church’s intercessory prayer as evidence for the doctrine of grace. The maxim stands in chapter 8 of the Indiculus (the Capitula Caelestini, a collection of papal teachings on grace transmitted with Pope Celestine I’s letter), a compilation generally attributed by scholars to Prosper (pseudo-Celestine, Indiculus, ch. 8).

In Orthodox theology, the principle is understood in a strong sense: the liturgy does not merely reflect theology but constitutes it. The worship of the Church is the primary place where the faith is lived, and therefore it is a theological source of the highest order. The Fathers did not first develop doctrines in the academy and then “apply” them to worship; rather, their theology arose from within the worshipping community and was tested by its consonance with the Church’s prayer.

Orthodox Reception of the Principle

The Orthodox understanding of lex orandi lex credendi differs from both the Catholic and Protestant approaches in important ways:

Against Protestant reductionism: Protestantism tends to subordinate worship to doctrine – the liturgy must conform to correct teaching, and any liturgical element not warranted by Scripture should be eliminated. In Orthodoxy, by contrast, the liturgy has its own integrity as a source of theological knowledge.
Against Catholic juridicalism: In Roman Catholic theology, the principle has sometimes been subordinated to the Magisterium – the teaching authority of the hierarchy determines what is doctrinally valid, and the liturgy must be reformed accordingly (as in the post-Vatican II liturgical reforms). In Orthodoxy, the liturgy stands as an independent witness that even the hierarchy cannot arbitrarily alter. The stability of the Orthodox liturgical tradition is itself a form of theological authority.
The Orthodox synthesis: In Orthodox theology, Scripture, Tradition, and worship form an organic, inseparable whole. The liturgy is the living voice of Tradition, the enacted Scripture, the embodied faith of the Church.

Schmemann’s Liturgical Theology

Background and Context

Fr. Alexander Schmemann (1921–1983) was the most influential liturgical theologian of the 20th-century Orthodox world. Born in Estonia to a Russian emigre family, educated at the St. Sergius Theological Institute in Paris (where he studied under Archimandrite Kiprian Kern and was influenced by the eucharistic ecclesiology of Fr. Nicholas Afanasiev), Schmemann spent the greater part of his career at St. Vladimir’s Seminary in Crestwood, New York, where he served as dean from 1962 until his death.

Tradition: Schmemann was a priest and theologian of the Orthodox Church in America (OCA), not of ROCOR or the Moscow Patriarchate. However, his works are widely read, studied, and cited across all Orthodox jurisdictions, including ROCOR and the Russian Orthodox Church. His influence transcends jurisdictional boundaries.

Key Works

Introduction to Liturgical Theology (1966; Russian original 1961)

In this work, Schmemann set out to define the field of “liturgical theology” as distinct from both the “theology of worship” (a systematic-theological treatment of what worship means) and “liturgical studies” (the historical-philological analysis of liturgical texts and rites).

Schmemann’s central argument is that liturgical theology is the primary theology – the theology that arises from the Church’s actual experience of worship, prior to and more fundamental than the secondary theological reflection of the academy. He was critical of what he saw as a “divorce” between worship and theology in the modern period, in which theology became an academic discipline severed from the prayer life of the Church, and worship became a matter of rubrical correctness emptied of theological content (Schmemann, Introduction to Liturgical Theology, ch. 1).

Schmemann traced the history of the Byzantine liturgical tradition, showing how the original eschatological character of Christian worship – the experience of the Kingdom of God breaking into the present – was gradually overlaid by allegory, mysticism, and ritualism in the medieval period. He argued for a recovery of the early Christian understanding of the liturgy as a passage from “this world” to the “world to come,” an actual participation in the Kingdom (Schmemann, Introduction to Liturgical Theology, chs. 2–4).

For the Life of the World (1963; revised 1973)

This more accessible work, originally written for the National Student Christian Federation, is perhaps Schmemann’s most widely read book. Its central thesis is that Christianity is not a “religion” in the conventional sense – a system of sacred rites, beliefs, and institutions – but a way of life in which the whole of creation is offered to God and transformed by grace.

Schmemann begins with the Eucharist as the paradigm of the Christian relationship to the world: in the Liturgy, bread and wine – the products of human labor and the gifts of creation – are offered to God and returned to us as the Body and Blood of Christ. This eucharistic movement (offering, transformation, communion) is the pattern for all of Christian existence (Schmemann, For the Life of the World, ch. 1).

Key themes include:

The sacramental worldview: The world itself is a sacrament – a means of communion with God – and the fall consists precisely in the loss of this sacramental vision. The Church’s sacraments are not isolated “sacred” rituals but the restoration of creation’s original vocation as the meeting-place of God and humanity (Schmemann, For the Life of the World, ch. 1).
Baptism and Pascha: Baptism is not merely a “rite of initiation” but a participation in Christ’s death and resurrection – a real passage from the old creation to the new (ch. 4).
Time and eschatology: The liturgical calendar sanctifies time not by making certain days “holier” than others but by revealing the eschatological meaning of all time – every Sunday is a “little Pascha,” a participation in the age to come (ch. 3).

Schmemann’s Critique of “Liturgical Piety”

One of Schmemann’s most provocative contributions was his critique of what he called the “liturgical crisis” in Orthodoxy. He argued that Orthodox Christians had largely lost the authentic understanding of their own liturgy, replacing it with:

Allegory and symbolism: The medieval Byzantine tradition of interpreting the liturgy as an allegory of Christ’s life (derived from commentaries like those attributed to Patriarch Germanus of Constantinople and elaborated by Nicholas Cabasilas and Symeon of Thessalonica) obscured the liturgy’s original eschatological meaning. In this allegorical framework, the Great Entrance represents Christ’s burial procession, the closing of the Royal Doors represents the sealing of the tomb, etc. Schmemann did not deny the legitimacy of symbolism but argued that this kind of illustrative allegory replaced the deeper symbolic realism of the early Church, in which the liturgy is not a representation of something absent but a manifestation of something present (Schmemann, Introduction to Liturgical Theology, ch. 4, “The Byzantine Synthesis”).
Individualistic piety: The transformation of the Eucharist from a communal act into an occasion for individual devotion – for example, the practice of infrequent communion, which Schmemann saw as a distortion of the original eucharistic practice (Schmemann, The Eucharist: Sacrament of the Kingdom, ch. 1).
Clericalism: The increasing separation of clergy and laity in worship, with the laity becoming passive spectators rather than active participants in the liturgical action.

Note: Schmemann’s critique has been controversial. Some Orthodox theologians and hierarchs have argued that he undervalued the medieval Byzantine liturgical tradition and that his emphasis on “early Church” practice risked a kind of liturgical primitivism. Others have seen his work as prophetic and essential. His emphasis on frequent communion has been widely received and has contributed to a significant shift in eucharistic practice across many Orthodox jurisdictions, though this remains unevenly applied.

Dogma Embedded in Hymns

The Liturgy as Doctrinal Source

One of the most distinctive features of Orthodox worship is the degree to which dogmatic theology is embedded in hymnography. The liturgical texts of the Orthodox Church – troparia, kontakia, stichera, canons, and other hymns – are not merely devotional expressions but precise theological statements set to music. To sing the liturgy is to confess the faith.

Examples

The Paschal Troparion

Khristos aneste ek nekron, thanato thanaton patesas, kai tois en tois mnemasi zoen kharisamenos.

“Christ is risen from the dead, trampling down death by death, and upon those in the tombs bestowing life.”

This brief hymn, sung repeatedly throughout the Paschal season, encapsulates the Orthodox theology of the Resurrection:

Christ is risen from the dead: The historical factuality of the Resurrection.
Trampling down death by death: The paradox of the cross – Christ conquers death not by avoiding it but by entering into it and destroying it from within. This reflects the patristic theology of the “divine deception” or “fishhook” metaphor (Gregory of Nyssa, Catechetical Oration, ch. 24).
Upon those in the tombs bestowing life: The universal scope of Christ’s victory – He descends to Hades and liberates the dead. This is depicted iconographically in the Orthodox Resurrection icon (the Anastasis), which shows Christ pulling Adam and Eve from their tombs.

Theotokion Hymns

The Theotokia (hymns addressed to the Mother of God) are not merely expressions of Marian devotion but precise christological and Mariological affirmations:

Theotoke Parthene, khaire, kekharitomente Marie, ho Kyrios meta sou…

“Rejoice, O Virgin Theotokos, Mary full of grace, the Lord is with you…”

This hymn (based on Luke 1:28) affirms:

Theotokos: Mary is the Mother of God – the christological definition of Ephesus (431).
Parthene (Virgin): Mary’s perpetual virginity – affirmed by the Fifth Ecumenical Council and consistently taught by the Fathers.
Kekharitomente (Full of Grace): Mary’s unique relationship to divine grace.

The Dogmatikon hymns sung at Saturday Vespers in the Octoechos (the eight-tone cycle) are among the most theologically dense hymns in the Orthodox tradition. Each one affirms the Incarnation, the two natures of Christ, and the role of the Theotokos, often engaging directly with the christological heresies condemned by the Councils.

The Hymn “Only-Begotten Son” (Ho Monogenes)

“Only-begotten Son and immortal Word of God, who for our salvation didst will to be incarnate of the holy Theotokos and ever-virgin Mary, who without change didst become man and wast crucified, O Christ our God, trampling down death by death, who art one of the Holy Trinity, glorified with the Father and the Holy Spirit: save us!”

This hymn, introduced into the liturgy in the 6th century [Disputed: the Byzantine tradition attributes it to Emperor Justinian I; the Syriac tradition attributes the same hymn to the non-Chalcedonian patriarch Severus of Antioch, and the ascription to Justinian “is by no means a certainty” in modern scholarship], is a comprehensive Christological confession sung at every Divine Liturgy. It affirms:

The eternal divine sonship of Christ (Only-begotten Son)
The Incarnation from the Theotokos and Ever-Virgin Mary
The immutability of the divine nature in the Incarnation (without change)
The reality of Christ’s suffering and death (was crucified)
Christ as “one of the Holy Trinity” – the Theopaschite formula endorsed by Constantinople II (553)
The co-equality and co-glorification of the three Persons of the Trinity

The Creed in the Liturgy

The Nicene-Constantinopolitan Creed is recited (or sung) at every Divine Liturgy, immediately before the Eucharistic prayer. Its liturgical placement makes it not merely a doctrinal statement but a confessional act: the faithful declare the faith they share before approaching the eucharistic table. The absence of the Filioque in the Orthodox recitation of the Creed is itself a liturgical-theological statement.

Kavanagh and the Western Dialogue

The concept of “primary theology” as liturgical theology was also developed independently by the Roman Catholic liturgical theologian Aidan Kavanagh, OSB (1929–2006), in his work On Liturgical Theology (1984). Kavanagh argued, in terms remarkably close to Schmemann’s, that the liturgical assembly is the primary theological act, and that systematic or academic theology is “secondary theology” – reflection on the primary experience of worship (Kavanagh, On Liturgical Theology, ch. 3).

Schmemann and Kavanagh were aware of each other’s work and shared certain fundamental intuitions, though they came from different ecclesial traditions. Kavanagh’s work has been read by Orthodox theologians as an independent confirmation of the Orthodox insight that worship is the fundamental form of theology, and it has contributed to ecumenical dialogue on liturgical questions.

Note: Kavanagh was a Roman Catholic and his work must be read in that context. His influence on Orthodox theology is indirect – he did not shape the Orthodox liturgical tradition itself, but his theoretical framework has been useful for articulating what Orthodox theology already practices.

The Russian Tradition of Theological Reflection Through Liturgical Texts

The Slavonic Liturgical Heritage

The translation of the Byzantine liturgy into Church Slavonic by Ss. Cyril and Methodius (9th century) and the subsequent Slavonic liturgical tradition created a distinctive Russian Orthodox engagement with liturgical theology. The Slavonic texts are not mere translations but theological achievements in their own right, sometimes preserving nuances lost in later Greek editions or introducing subtle shifts in emphasis.

The Slavonic liturgical heritage means that Russian Orthodox Christians encounter dogmatic theology primarily through worship rather than through academic study. For most of Russian Orthodox history, the liturgy was the primary catechetical instrument – the means by which the faithful learned the faith.

Key Figures in the Russian Liturgical Tradition

St. Dimitri of Rostov (1651–1709): Compiled the Chetii-Minei (Menologion – Lives of the Saints arranged by month for daily reading), a massive liturgical-hagiographic work composed over the years 1684–1705 that served as spiritual reading for generations of Russian Orthodox Christians.
St. Filaret (Drozdov) of Moscow (1782–1867): His Catechism drew extensively on liturgical texts as doctrinal sources, demonstrating the principle of lex orandi lex credendi in catechetical practice.
St. Theophan the Recluse (1815–1894): His spiritual writings frequently draw on liturgical texts as the basis for theological and devotional reflection, exemplifying the Russian tradition of reading the services as theology.
Archimandrite Kiprian (Kern) (1899–1960): His Eucharist (Evkharistiya) is a major study of the eucharistic liturgy from the Russian theological perspective, combining historical scholarship with liturgical-theological reflection. Kern taught at St. Sergius and was a direct influence on Schmemann.

ROCOR and Liturgical Tradition

Tradition: ROCOR-specific

ROCOR has placed particular emphasis on the preservation of pre-revolutionary Russian liturgical practice, including:

The use of traditional Slavonic liturgical texts without modernization
Adherence to the Julian Calendar
The preservation of the Znamenny and other traditional Russian chant traditions alongside the more common harmonized singing styles
Resistance to liturgical reforms or abbreviations

This conservatism is understood within ROCOR not as mere traditionalism but as fidelity to the living liturgical Tradition of the Russian Church. The liturgy, in this view, is not something that can be “updated” without risk of theological loss, because the liturgical texts themselves carry and transmit the faith.

Note: The question of liturgical language (Church Slavonic vs. vernacular) has been debated in Russian Orthodoxy since the early 20th century. Some Russian Orthodox communities (especially in the OCA and in some Moscow Patriarchate parishes) have introduced varying degrees of vernacular language. ROCOR has generally maintained Church Slavonic, viewing it as an integral part of the liturgical tradition. This is a matter of ongoing discussion, not a dogmatic question.

The Liturgy and Theological Method

Implications for How Theology Is Done

If the liturgy is indeed a primary theological source, this has significant implications for theological method:

Theology must be liturgical: The theologian who does not worship is cut off from the primary source of theological knowledge. Evagrius of Pontus’s famous dictum applies: “If you are a theologian, you will pray truly; and if you pray truly, you are a theologian” (Evagrius, On Prayer 60 [61 in some numberings]; the work was transmitted under the name of Nilus).
Theological innovation must be tested liturgically: Any theological proposal that contradicts the prayer of the Church is suspect. The liturgy serves as a check on theological speculation.
The community, not the individual, is the primary theological subject: Since the liturgy is inherently communal, liturgical theology resists the modern tendency to treat theology as an individual intellectual enterprise.
Theology is doxological: The ultimate purpose of theology is not information but praise – the glorification of God. Theology that does not lead to worship has lost its way (Schmemann, For the Life of the World, ch. 1).
