Orthodox
Fasting

The Church did not invent fasting. She received it. The discipline reaches back past the Apostles and past the Incarnation itself, into the religious life of God's covenant people under the Old Testament. To understand why Orthodox Christians fast, one must first understand what the Church inherited and how the Holy Spirit prepared that inheritance across centuries of Jewish practice before filling it with the fullness of Christ.

The most formal institutionalization of fasting in Mosaic legislation appears in Leviticus 16, where the observance of Yom Kippur, the Day of Atonement, is commanded in terms that carry unmistakable weight. The text prescribes that the Israelites are to "afflict their souls" (Leviticus 16:29, 31). The Septuagint renders this phrase as tapeinōsate tas psychas hymōn, and the Church Fathers consistently read it as commanding bodily fasting alongside interior contrition: body and soul together, offered to God in humility. The Mishnah tractate Ta'anit elaborates the regulations governing communal fasting, showing that by the rabbinic period the practice already carried a developed institutional structure. That structure was the inheritance the Church received.

The most theologically charged fasting text in the prophetic corpus is Isaiah 58, which the Church has always read as the prophetic conscience of the entire tradition. God rebukes a people who fast outwardly while remaining unjust: "Is not this the fast that I choose: to loose the bonds of injustice, to undo the thongs of the yoke, to let the oppressed go free, and to break every yoke? Is it not to share your bread with the hungry?" (Isaiah 58:6-7). The prophetic word does not abolish fasting; it refuses to allow the bodily act to substitute for justice. Basil of Caesarea and John Chrysostom both cite Isaiah 58 at length in their homilies on fasting, making the connection between abstinence from food and generosity to the poor as old as the prophetic tradition itself.

Across the Hebrew scriptures, fasting appears as a preparation for and intensification of prayer. Daniel fasts in anguish for his people during the Babylonian captivity (Daniel 9). Ezra proclaims a fast before the dangerous journey from Babylon to Jerusalem: "that we might deny ourselves before our God, to seek from him a safe journey" (Ezra 8:21). Nehemiah fasts for days upon hearing of Jerusalem's condition. Esther calls a three-day fast by the entire Jewish community before approaching the king. The pattern is consistent: fasting is what the body does when the soul turns urgently toward God. The Church received this conviction and has never set it aside.

When Jesus entered the Judean wilderness after his baptism and fasted forty days, the Church was already learning the deepest reason for fasting. He was not performing a religious exercise. He was entering, in the fullness of his humanity, into the same condition of creaturely dependence and bodily discipline that the Law and the Prophets had always demanded. The Church's Great Lent is rooted precisely here: we fast forty days because the Lord fasted forty days, and his fast is the pattern and the ground of ours.

In the Sermon on the Mount, Jesus addresses fasting in Matthew 6:16-18 with a phrase that the Church has never read as anything other than a presupposition: "when you fast," not "if you fast." He does not institute a new fasting practice; he corrects the motivation of an existing one. "Do not look dismal, like the hypocrites, for they disfigure their faces that their fasting may be seen by men. But when you fast, anoint your head and wash your face, that your fasting may not be seen by men but by your Father who is in secret." Every generation of the Church's pastors has read the word "when" as binding: fasting is assumed as a normal feature of Christian life, not an optional supplement for those with a taste for asceticism.

The question of the bridegroom in Mark 2:18-20 supplies the eschatological foundation of the entire tradition. When asked why his disciples do not fast, Jesus replies that the wedding guests cannot fast while the bridegroom is with them. "The days will come when the bridegroom is taken away from them, and then they will fast in that day." The Church fasts because she lives in the time of the bridegroom's absence, between the Ascension and the Second Coming. The fast is the body's way of saying: the Lord has not yet returned, and we long for him. Every Wednesday and Friday, every Great Lent, is this same confession made in the flesh.

The Didache, dateable to the late first or early second century, provides the earliest documentary evidence for the institutionalization of Christian fasting on specific days. It prescribes Wednesday and Friday as Christian fast days, deliberately distinguishing the community from Jewish practice on Monday and Thursday. Wednesday commemorates the betrayal of Christ, Friday the crucifixion. The Church has kept these days continuously from the Didache to the present, a fasting discipline now nearly two thousand years old. The Shepherd of Hermas, writing a generation later, connects the Wednesday and Friday fasts directly to almsgiving: the food saved by the fast belongs to the widow and the orphan. The fast and the poor are inseparable from the beginning.

The Fathers of the Church did not create the theology of fasting. They received it, examined it from every angle, and articulated what the Church had always known and practiced with a theological precision that subsequent generations have never substantially improved on. From Tertullian in Carthage to Basil in Cappadocia to Cassian in Gaul, the great doctors of the Church treated fasting not as a peripheral discipline but as a constitutive feature of Christian life, deserving the same careful attention as any article of faith.

Among all the Fathers, Basil the Great (c. 330-379) left the fullest theological account of Christian fasting. His Homilies on Fasting, preached during Great Lent, begin with a startling claim: "Fasting is as old as humanity itself. It was prescribed in Paradise. Adam received the commandment 'You shall not eat of the tree of knowledge of good and evil.' The prescription 'you shall not eat' is a law of fasting and abstinence." By locating the origin of fasting in the Garden, Basil places it at the very root of the human relationship with God. The fast is not a penitential afterthought grafted onto the Christian life. It is a constitutive feature of creaturely existence before God.

Basil develops the social theology of fasting with particular force. The fast is incomplete, he argues, unless the money saved by abstaining from costly food is given to the poor. He castigates those who fast from meat but dine on expensive fish, or who substitute one indulgence for another. His connection to Isaiah 58 is explicit: "You do not eat flesh. Neither do you give bread to the hungry. You do not drink wine. But neither do you give water to the thirsty." For Basil, fasting and almsgiving are not parallel disciplines; they are a single act of love toward God and neighbor.

John Chrysostom (c. 349-407) approached fasting through the lens of pastoral urgency. Preaching in Antioch and later in Constantinople, he returned repeatedly to the question of what fasting is actually for: "What good is it, I ask, if we abstain from birds and fish, but we bite and devour our brothers and sisters?" The rhetorical question is sharp and intentional. A fast that leaves the poor unfed, the enemy unreconciled, the angry tongue unchecked, is not a Christian fast at all. Chrysostom does not use this argument to dissolve the bodily discipline of fasting; he uses it to insist that the bodily discipline only makes sense in a life that is genuinely turned toward God and the neighbor.

John Cassian (c. 360-435) holds a unique place in the history of Christian fasting as the transmitter of Egyptian desert wisdom to the Latin West. Formed among the monks of Egypt and Palestine, Cassian brought their accumulated teaching on the discipline of appetite to the monasteries of Gaul in his Institutes and Conferences. His central contribution was the principle of discretio, discernment: the Egyptian Fathers did not prescribe a single universal fasting rule, but adapted the discipline to the individual monk's age, health, work, and spiritual condition. The role of the spiritual father in establishing an individual's fasting practice has been, from Cassian forward, the Church's mechanism for holding together the strictness of the ideal and the mercy required by actual human conditions.

The Church has never left fasting to private inclination alone. The sacred canons carry the weight of the Church's collective discernment across centuries, and they speak about fasting with the same authority they bring to questions of doctrine and sacramental practice. To read the canonical tradition on fasting is to understand that the discipline belongs not to the individual but to the Body, and that the Body has always taken its preservation seriously.

The Apostolic Canons, appended to the Apostolic Constitutions and dated in their present form to the late fourth century, include direct legislation on fasting. Canon 64 prescribes that clergy who do not observe the Wednesday and Friday fasts, except for bodily illness, are to be deposed, while laymen are to be excommunicated. Canon 69 mandates strict fasting throughout Holy Week. These canons demonstrate that by the fourth century, the Wednesday and Friday fasts had become a canonical obligation of the entire Church, binding on clergy and laity alike, and treated with the seriousness attached to any essential feature of Christian life.

The Council of Gangra, convened around 340 AD in Paphlagonia, addressed a danger the canonical tradition rarely had to confront: not the laxity of those who refused to fast, but the Gnostic rigorism of those who fasted in a spirit of contempt for creation. The followers of Eustathius of Sebaste had developed teachings that despised marriage, condemned meat-eating in all circumstances, and promoted unauthorized fasting that disrupted the common life of the Church. Canon 19 of Gangra anathematizes those who fast on Sunday out of contempt for the Eucharistic feast. The canon's witness is this: Orthodox fasting is never a statement against creation. It is an offering within creation, made in the same spirit of thanksgiving and self-gift that governs the Eucharist itself.

The Quinisext Council, convened at Constantinople in 692 AD under Emperor Justinian II, produced the fullest canonical statement on fasting in Orthodox history. Its canons address the full range of fasting practice with a precision that reflects centuries of accumulated tradition. Canon 56 forbids eating eggs and cheese on the Saturdays and Sundays of Great Lent. Canon 89 prescribes strict fast throughout Holy Week until midnight on Holy Saturday, when the Paschal feast begins. Canon 55 directly addresses the divergence between Eastern and Western practice, requiring that the Roman Church observe the Eastern rule prohibiting Saturday fasting. Rome never accepted this claim, and the dispute became one of the grievances of the Schism period. The Quinisext canons remain in force in the Orthodox Church to this day, received and commented upon in the Pedalion of St. Nikodemos of the Holy Mountain.

The Orthodox fasting calendar is not a collection of arbitrary regulations. It is the Church's calendar of prayer, expressing in bodily terms what the liturgical year expresses in worship. Each fast is connected to a feast, each period of abstinence to a moment in the history of salvation. To learn the fasting calendar is to learn the liturgical year from the inside, through the body's participation in its rhythm.

Great Lent is the oldest, longest, and most demanding of the Orthodox fasting periods. Its origins reach to the very beginnings of Christian practice: the pre-baptismal fast, observed by catechumens preparing for baptism at the Paschal Vigil, is attested from the early second century. As the catechumenate evolved and infant baptism became normative, this fast developed into a general penitential and preparatory fast for the entire congregation. By the fourth century it had been standardized to forty days, in conscious imitation of Christ's forty-day fast in the Judean desert and the forty-day fasts of Moses on Sinai and Elijah on the way to Horeb. Alexander Schmemann, whose Great Lent remains the finest theological account of this season in English, described it as a "bright sadness": simultaneously a mourning over the distance between the Church and her Lord and an anticipation of the joy that is coming. We do not fast for forty days in gloom. We fast in hope.

The Apostles' Fast begins on the Monday after the Sunday of All Saints and concludes on June 28/29, the feast of Sts. Peter and Paul. Its length varies from year to year depending on the date of Pascha. The Dormition Fast (August 1-14) prepares for the feast of the Dormition of the Most Holy Theotokos on August 15. It is treated as second only to Great Lent in severity, with no fish permitted throughout except on the Feast of the Transfiguration (August 6). The Nativity Fast (November 15 through December 24) is a gentler preparation for the Feast of the Nativity, with fish generally permitted on most days. Thomas Hopko's The Winter Pascha reads this season as the Church's annual pilgrimage through darkness toward the Light that has no evening.

Wednesday and Friday remain the primary weekly fast days of the Orthodox calendar throughout the year, except during fast-free weeks. The theological rationale assigned to these days: Wednesday commemorates the betrayal of Christ by Judas, and Friday the crucifixion. Single-day fasts of particular weight include the Exaltation of the Holy Cross (September 14), the Beheading of John the Baptist (August 29), and the Eve of Theophany (January 5). These are observed as strict fasts even when they fall on Saturday or Sunday, an exception to the general rule against those days. Fast-free weeks (Bright Week, the week after Pentecost, the week of the Publican and Pharisee, and the period between Nativity and the Eve of Theophany) remind us that fasting is never an absolute value but is always calibrated to the liturgical moment. The Church also feasts, and feasts without apology.

Orthodox fasting has always been precise. The Church's Typikon specifies, in considerable detail, not simply that one fasts but how: what is eaten and what is not, at what hour of the day, on which days of which weeks. This precision is not legalism. It is the practical expression of a conviction that the body's offering to God is a real offering, that it matters what we actually give up, and that the discipline of abstinence only disciplines if it involves something we would genuinely prefer to have.

The Typikon operates with a carefully graduated scale of fasting severity. At the most demanding end stands xerophagy, literally "dry eating": abstinence from all cooked food, permitting only bread, water, salt, and raw vegetables. This was the standard of the Egyptian desert monks and remains the Athonite rule for the first week of Great Lent and Holy Week. Moving along the scale: cooked vegetables without oil (moderate fast), cooked vegetables with olive oil (a somewhat relaxed fast, permitted on Saturdays and Sundays of Great Lent), wine with oil (permitted on certain weekdays of lighter fasting seasons), and fish (permitted on most Saturdays and Sundays outside of Great Lent and the Dormition Fast). The most severe fasting days ask the body for more; the Church's feast days ask it for less. The graduated scale is the Church's way of ensuring that fasting is neither absolute rigidity nor absolute indulgence.

The foods abstained from in the Orthodox fast belong to several categories: meat and meat products, poultry, dairy products (milk, cheese, butter, eggs), fish with certain exceptions, olive oil, and wine. The specific inclusion of olive oil and wine reflects the Mediterranean agricultural world in which the fasting rules developed. In the ancient and medieval Mediterranean, olive oil was the primary cooking fat and wine the universal beverage. To abstain from them was a genuine deprivation, not a dietary curiosity. The principle embedded in these rules is abstinence from the richest and most enjoyed foods of one's culture, not adherence to a specific list regardless of cultural context.

The question of how rules developed in a Mediterranean context apply in non-Mediterranean cultures has been addressed with increasing seriousness in North American Orthodox communities. If olive oil played one role in Palestine, a different fat plays the equivalent role in a different culture. The Church has generally addressed this by applying the spirit of the fasting rule (abstinence from the richest and most enjoyed foods) while adapting its specific letter to the cultural context. The confessor remains the essential mediator of this adaptation: it is the spiritual father who helps each Christian find the specific form the fast should take in his or her particular life.

The divergence between Eastern and Western fasting practice did not begin with the Great Schism of 1054. It can be traced through several centuries of gradual differentiation, and tracing it helps clarify what the Orthodox tradition has preserved and why that preservation matters. To see what other Christian communities did with their fasting disciplines over the centuries is to appreciate more fully what the Church has kept.

The most revealing early point of divergence is the Saturday fast. The Eastern churches maintained the ancient prohibition against Saturday fasting, rooted in the Apostolic Canons, on the grounds that Saturday commemorates the Sabbath rest and is therefore a day of joy, not penance. The Roman church had developed a tradition of Saturday fasting as well, attested by Tertullian in North Africa. The Quinisext Council's Canon 55 insisted that the Eastern rule applied to the Roman church as well. Rome declined to accept this. The dispute is not trivial: it reflects different theological readings of creation, the Sabbath, and the meaning of the liturgical week, and it established a pattern of divergence that would deepen over the following centuries.

After the Schism of 1054, the Western fasting tradition developed along its own lines. The system of Ember Days, quarterly fasting days at the beginning of each of the four seasons, had no Eastern parallel. The medieval Western Lenten discipline focused primarily on abstinence from meat, while dairy and eggs were initially permitted and then progressively restricted and later relaxed again. The Protestant Reformation brought a largely negative response to prescribed fasting as a church discipline. Luther accepted personal fasting as useful but rejected institutional fasting as a meritorious work. Calvin was similarly ambivalent. As a result, the structured fasting calendar of the ancient church largely disappeared from Protestant communities.

The Second Vatican Council's reforms, and especially the post-conciliar discipline established by the Paenitemini document of 1966, reduced Western Catholic fasting obligations to Ash Wednesday and Good Friday as obligatory fast days and Fridays of Lent as days of abstinence from meat. What had been a rich and demanding fasting calendar was simplified almost out of recognition. The Orthodox Church, by contrast, has maintained the full ancient calendar: four great fasts, Wednesday and Friday throughout the year, the single-day fasts of particular saints, and the fast-free weeks. The comparison is instructive without being polemical. It shows what was preserved and what was not.

Among the Protestant traditions, one figure stands out for his deliberate recovery of the ancient practice: John Wesley, the founder of Methodism. Wesley studied the early Church Fathers attentively and was struck by the evidence for Wednesday and Friday fasting in the Didache, Tertullian, and the Apostolic Constitutions. He restored regular Wednesday and Friday fasting to his Methodist communities, citing the authority of the primitive Church and arguing that the neglect of fasting was a mark of spiritual decline in the Protestant world. Wesley's example is a reminder that the patristic fasting tradition is not merely an Orthodox possession; it is the ancient patrimony of all Christians, and some outside the Orthodox Church have recognized as much.

The monasteries have always been the guardians of the full fasting tradition. Without them, the demanding precision of the Orthodox fasting calendar would likely have been worn smooth by pastoral accommodation long ago. It is the monks who have kept the strictest observance, who have written about fasting with the most searching precision, and who have demonstrated across sixteen centuries that the ancient discipline is not merely theoretical but livable.

The Apophthegmata Patrum, the collection of sayings and stories from the Egyptian desert monastics of the fourth and fifth centuries, contains abundant material on fasting as spiritual warfare against the passions. Abba Moses instructs: "Fasting and vigil are the tools of the monk." The standard Egyptian practice, as John Cassian describes it, was to eat once a day in the evening, with a meal consisting of bread, salt, oil, and vegetables. Individual practice varied according to the elder's direction. The desert tradition was acutely aware that fasting could generate the very passion it was meant to mortify: Abba Poemen repeatedly warns against excessive fasting that draws attention to itself or disrupts fraternal charity. The fathers were not interested in records of abstinence. They were interested in purity of heart, and they understood that fasting serves that purpose rather than replacing it.

The monastic republic of Mount Athos in northern Greece has maintained the strictest form of the Orthodox fasting calendar from the medieval period to the present. Bishop Kallistos Ware, who has written extensively on Athonite spirituality, describes a fasting practice that includes two meals daily on non-fasting days, one meal in the mid-afternoon on moderate fasting days, and strict xerophagy with no cooked food on the most severe fasting days of the first week of Great Lent and Holy Week. The Athonite calendar observes not only the four great fasts but every Wednesday and Friday throughout the year and all the single-day fasts, making the total number of fasting days over two hundred per year. Mount Athos is not a museum exhibit of ancient asceticism. It is a community of living men for whom this discipline is the normal rhythm of a normal day, and it has been so, without interruption, for over a thousand years.

The Philokalia, the anthology of hesychast spiritual texts compiled by St. Nikodemos of the Holy Mountain and published in 1782, includes repeated references to fasting as a prerequisite for pure prayer. The hesychast tradition, centered on the continuous practice of the Jesus Prayer and the pursuit of divine light, understood fasting as essential for stilling the bodily passions that distract the mind from God. Without the discipline of the body, the interior prayer cannot be sustained. This is not an archaic notion. It is the consistent testimony of those who have actually tried both.

John Climacus (c. 579-649), abbot of the Monastery of Sinai, devoted Step 14 of his Ladder of Divine Ascent to fasting. He writes with the precision of a man who has observed the passions carefully: "The fast is a violence done to nature, a cutting away of everything that nature desires for the sake of pleasure." He is emphatic that fasting is not an end in itself but a means, and he warns at length against the spiritual pride that can accompany excessive abstinence. The monk who fasts beyond his elder's prescription, who invents his own austerities in order to be admired, has turned a means of humility into an occasion for vanity. The ladder of divine ascent cannot be climbed by a proud body any more than by a proud soul.

The Orthodox fasting tradition has never been a dead letter. It has been lived out across wildly different cultures, climates, and economies, and in each case the Church has found ways to honor the spirit of the fast while attending honestly to the realities of human life. The tradition's record of pastoral adaptation is not a history of compromise; it is a history of the Spirit guiding the Church to maintain the substance of the discipline across every circumstance into which she has been sent.

One of the most instructive cases of pastoral adaptation in the fasting tradition concerns the indigenous communities of Alaska, who began receiving Orthodox Christianity through Russian missionary work beginning in the late eighteenth century. St. Herman of Alaska (c. 1756-1837) and the missionaries who followed him encountered peoples whose subsistence economy was centered entirely on hunting sea mammals, fishing, and gathering, with no access to the Mediterranean agricultural products (olive oil, wine, bread, fish in the European sense) around which the fasting calendar had developed. The response of the Church was pastorally imaginative: sea mammals were understood as the Alaskan equivalent of "fish" for fasting purposes, reflecting the recognition that the fasting rules were not about the specific foods listed in the Typikon but about abstinence from the richest and most enjoyed foods in a given cultural context. This case is not an exception that undermines the fasting rule. It is an illustration of what the fasting rule actually means.

The pre-revolutionary Russian Orthodox Church maintained a fasting discipline among its laity that was, in many communities, closer to the monastic standard than to what was observed in contemporary Greek practice. Great Lent in Russia was observed with considerable strictness among the peasant majority, with complete abstinence from meat and dairy throughout the seven weeks and periods of xerophagy on the most severe days. The disruption caused by the Soviet period was catastrophic: the destruction of parish life, the closure of monasteries, the elimination of religious education, and the active persecution of those who fasted publicly. The post-1991 revival of Orthodox practice in Russia has involved a substantial recovery of Lenten observance, one of the more remarkable instances of a fasting tradition reasserting itself after a seventy-year interruption.

The largest single development in North American Orthodoxy in the past half-century has been the influx of converts from Western Christian backgrounds, for whom the Orthodox fasting calendar is entirely new and requires substantial formation. The various North American jurisdictions have developed somewhat different approaches to this challenge. ROCOR has generally maintained the strictest application of the Typikon and has expected converts to adopt the full fasting calendar as a condition of serious Orthodox discipleship. The OCA and Antiochians have generally advocated a more graduated approach: begin with Wednesday and Friday, add Great Lent, and incorporate the other fasting periods over time as the prayer life deepens. The canonical tradition has always made room for medical exemptions and pastoral accommodation. Chrysostom writes that God does not desire the body's destruction but its sanctification, and that a sick person who offers her illness to God is making a greater offering than the healthy person who merely abstains from food.

All the canons, all the Typikon regulations, all the graduated scales of severity, all the pastoral accommodations made for Alaska and Russia and converts and the sick: they all point toward a single truth. Orthodox fasting is a theological act. It is not primarily a health practice, a cultural tradition, or a psychological exercise, though it may touch on all of these. It is the body's participation in the Church's prayer, the offering of the whole person, not just the soul, to the living God.

Orthodox theology understands fasting primarily as askesis, a Greek word meaning training or exercise, borrowed from the vocabulary of athletic preparation. Paul uses exactly this image in 1 Corinthians 9:24-27: "Every athlete exercises self-control in all things. They do it to receive a perishable wreath, but we an imperishable one. I do not run aimlessly; I do not box as one beating the air. But I discipline my body and keep it under control." The logic of ascesis is not that the body is evil or that pleasure is wicked. It is that the human will, weakened by the Fall, requires habitual discipline to function as it was created to function, in ordered relation to God rather than in servitude to appetite. Fasting is the training ground of the will. Georges Florovsky argued that this understanding of ascesis is fundamentally Christological: the Christian trains not by personal willpower alone but by participation in Christ's own struggle against the temptations of the flesh, reenacting in his or her own body the dynamic of Christ's forty-day fast and the victory of the cross over death.

The thread of Isaiah 58 runs continuously through the entire Orthodox theology of fasting. Basil, Chrysostom, the Desert Fathers, and the canons all insist that the money and food saved by fasting must be given to the poor, and that a fast that leaves the hungry unfed is not a Christian fast but a dietary regime. This connection is not incidental or merely ethical. It reflects the understanding that Christian fasting is always ecclesial and social, never merely personal. The person who fasts identifies with the hungry neighbor, and this identification is itself a form of prayer and a means of escaping the illusion of self-sufficiency. The body that has been hungry, even voluntarily, for a few hours knows something about the body that is hungry without choice.

The eschatological dimension of fasting, rooted in Christ's saying about the bridegroom taken away (Mark 2:20), is the most theologically distinctive element of the Orthodox theology of fasting and the one that most clearly separates it from any merely therapeutic or ethical discipline. The Church fasts because she lives in the time between the Lord's first and second coming, the time of the bridegroom's absence. The fast is the body's way of expressing what the prayer "Come, Lord Jesus" (Revelation 22:20) expresses in words: that this world, however good, is not yet the Kingdom, and that the Church longs for the fullness that has not yet come. Schmemann put it exactly: "Fasting is the only means by which man reasserts his spiritual nature and destiny in the face of the all-embracing power of matter over him." To fast is to insist that we are not merely our appetites, that we were made for something more than food and drink, that the Kingdom is the goal and destination of everything we do.

The tradition has never lost sight of the Eucharistic dimension of this eschatological orientation. The traditional discipline of preparing for Holy Communion includes fasting from midnight, approaching the Body and Blood of Christ with an empty body and a recollected soul. This Eucharistic fast concentrates and intensifies the same theological logic that governs all Orthodox fasting: the body prepared to receive God is a body emptied of its ordinary preoccupations. The fast and the feast belong together, as Lent belongs to Pascha, as the vigil belongs to the dawn.

Paul's exhortation in Romans 12:1 to "present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship" has been the constant theological grammar of the Church's fasting. The body is not left outside the act of worship but is offered within it. Kallistos Ware argues in The Orthodox Way that Orthodox fasting flows directly from the theology of the Incarnation: because God became embodied in Jesus Christ, the human body is not a disposable shell but the locus of sanctification, and its disciplining through fasting is a participation in the ongoing work of theosis, the deification of the whole human person, body and soul together.
