Morris ClarkReceiving Holy Communion is the highest moment of the Orthodox Christian life. In the Divine Liturgy, the faithful are invited to partake of the very Body and Blood of our Lord Jesus Christ—not as a symbol, not as a mere memorial, but as the true and life-giving presence of the Savior Himself. Metropolitan Kallistos Ware writes that the Eucharist is “the most intimate union we can have with God this side of death”. Because of the profound nature of this mystery, the Orthodox Church provides a rich tradition of preparation, including a specific set of Orthodox prayers before Communion designed to ready the soul for this sacred encounter.
The prayers before Holy Communion serve multiple purposes. They help us examine our consciences, confess our unworthiness, express our faith in the Real Presence, and ask God to receive us with mercy rather than judgment. St. Paul warns, “Whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of the body and blood of the Lord” (1 Corinthians 11:27). The pre-communion prayers are our safeguard against approaching the Chalice carelessly or irreverently.
This guide will walk you through everything you need to know about preparing for Holy Communion in the Orthodox tradition. You will learn about the Canon of Preparation, the shorter prayers said immediately before approaching the Chalice, the role of confession and fasting, and the practical steps of receiving the Holy Mysteries. Whether you are a lifelong Orthodox Christian or an inquirer learning about the faith, this guide will help you approach the Chalice with reverence, repentance, and joy.
Why Preparation Matters
The Orthodox Church takes the preparation for Holy Communion seriously because what happens at the Chalice is not a ritual or a symbol. It is the reception of God Himself. You are receiving the actual Body and Blood of Jesus Christ, the Second Person of the Holy Trinity, under the forms of bread and wine.
St. Paul’s warning in 1 Corinthians 11 is direct: “Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of the body and blood of the Lord. Let a person examine himself, and so eat of the bread and drink of the cup. For anyone who eats and drinks without discerning the body eats and drinks judgment upon himself” (1 Corinthians 11:27-29).

The preparation for Holy Communion is not about earning God’s favor or achieving a state of sinless perfection. No one is truly worthy of receiving Christ. The prayers acknowledge this repeatedly. Instead, preparation is about approaching with a repentant heart, having done what you can to reconcile with God and neighbor, and asking for mercy rather than judgment.
The three traditional pillars of preparation are prayer, fasting, and confession.
The Three Pillars of Preparation
1. Prayer: The Pre-Communion Prayer Rule
The most direct form of preparation is the pre-communion prayer rule, a set of prayers said either the evening before or the morning of Divine Liturgy. The full rule is called the Canon of Preparation. It is a series of troparia (short hymns) and petitions drawn from the liturgical tradition of the Church, asking for mercy, cleansing, and the grace to receive Communion without condemnation.
2. Fasting: Physical Preparation
Fasting before Communion is an ancient practice that prepares the body to receive the Lord. The traditional rule is to fast from all food and drink from midnight before a morning Liturgy. Nothing should be consumed—not even water or coffee—so that Christ’s Body and Blood are the first things received that day . For evening Liturgies, an eight-hour fast is typically required. Exceptions exist for illness, pregnancy, medication needs, or shift work, but these should be discussed with one’s priest.
3. Confession: Sacramental Preparation
Confession is not merely about listing sins like checking boxes on a list. It is about examining your conscience, bringing your thoughts and struggles into the light, and receiving absolution from your spiritual father. The frequency of confession varies based on one’s priest’s guidance, but a general rule is to confess every four to six weeks, or before each time one communes. The prayers before Communion assume you are in a state to receive; they cannot substitute for the Mystery of Confession with your priest.
The Full Canon of Preparation for Holy Communion
The full Canon of Preparation is traditionally read the evening before receiving Holy Communion, often as part of Small Compline. It can also be read the morning of Liturgy. The canon is organized into nine Odes, each with an Irmos (a thematic hymn) and several troparia.
The canon begins with the customary opening prayers of the Orthodox tradition.
Opening Prayers
Through the prayers of our holy fathers, O Lord Jesus Christ our God, have mercy on us. Amen.
Glory to Thee, our God, glory to Thee.
O Heavenly King, Comforter, Spirit of Truth, Who art everywhere present and fillest all things, Treasury of good things and Giver of Life, come and dwell in us, and cleanse us of all impurity, and save our souls, O Good One.
Holy God, Holy Mighty, Holy Immortal, have mercy on us. (Thrice)
Glory to the Father, and to the Son, and to the Holy Spirit, both now and ever, and unto the ages of ages. Amen.
O Most Holy Trinity, have mercy on us. O Lord, blot out our sins. O Master, pardon our iniquities. O Holy One, visit and heal our infirmities, for Thy name’s sake.
Lord, have mercy. (Thrice)
Glory to the Father, and to the Son, and to the Holy Spirit, both now and ever, and unto the ages of ages. Amen.
Our Father, Who art in the heavens, hallowed be Thy Name. Thy kingdom come. Thy will be done, on earth as it is in heaven. Give us this day our daily bread, and forgive us our debts as we forgive our debtors; and lead us not into temptation, but deliver us from the evil one.
Through the prayers of our holy fathers, O Lord Jesus Christ our God, have mercy on us. Amen.
Lord, have mercy. (Twelve times)
Glory to the Father, and to the Son, and to the Holy Spirit, both now and ever, and unto the ages of ages. Amen.
O come let us worship God, our King.
O come let us worship and fall down before Christ, our King and God.
O come let us worship and fall down before Christ Himself, our King and God.
Psalms 22, 23, and 115
After the opening prayers and the Trisagion, three psalms are read: Psalm 22 (The Lord is my Shepherd), Psalm 23 (The earth is the Lord’s), and Psalm 115 (I believed, wherefore I spake)Â .
Troparia
Following the psalms, the following troparia are said:
Tone 8:
Disregard my transgressions, O Lord Who was born of a Virgin, and purify my heart, and make it a temple for Thy spotless Body and Blood. Let me not be rejected from Thy presence, O Thou Who hast great mercy without measure.
Glory to the Father, and to the Son, and to the Holy Spirit.
How can I who am unworthy dare to come to the Communion of Thy Holy Things? For if I should dare to approach Thee with those that are worthy, my garment betrayeth me, for it is not a festal robe, and I shall cause the condemnation of my greatly-sinful soul. Cleanse, O Lord, the pollution from my soul, and save me, as Thou art the Lover of mankind.
Both now and ever, and unto the ages of ages. Amen.
Greatly multiplied, O Theotokos, are my sins; unto Thee have I fled, O pure one, imploring salvation. Do thou visit mine enfeebled soul, and pray to thy Son and our God that He grant me forgiveness for the evil I have done, O thou only blessed one.
Psalm 50 (The Great Penitential Psalm)
Psalm 50 (in the Septuagint numbering) follows, beginning:
Have mercy on me, O God, according to Thy great mercy; and according to the multitude of Thy compassions blot out my transgression. Wash me thoroughly from mine iniquity, and cleanse me from my sin…
The Canon of Preparation, Ode I
Irmos, Tone 2:
Come, O ye people, let us sing a hymn to Christ our God, Who divided the sea and guided the people whom He brought out of the bondage of Egypt; for He is glorified.
Refrain:Â Create in me a clean heart, O God, and renew a right spirit within me.
May Thy holy Body be unto me the Bread of life eternal, O Compassionate Lord, and Thy precious Blood be also the healing of my many forms of illness.
Refrain:Â Cast me not away from Thy presence, and take not Thy Holy Spirit from me.
Defiled by unseemly deeds, I the wretched one am unworthy, O Christ, of the communion of Thy most pure Body and divine Blood, which do Thou vouchsafe me.
Glory to the Father, and to the Son, and to the Holy Spirit, both now and ever, and unto the ages of ages. Amen.
O blessed Bride of God, O good soil that grew the Corn untilled and saving to the world, vouchsafe me to be saved by eating it.
Ode III
Irmos:
By establishing me on the rock of faith, Thou hast enlarged my mouth over mine enemies, for my spirit rejoiceth when I sing: There is none holy as our God, and none righteous beside Thee, O Lord.
Tear drops grant me, O Christ, to cleanse my defiled heart, that, purified and with a good conscience, I may come with faith and fear, O Master, to the communion of Thy divine Gifts.
Odes IV-IX
The canon continues through the remaining odes, each containing petitions for cleansing, sanctification, and the grace to receive Communion without condemnation. The full text of the canon can be found in any standard Orthodox prayer book.

The Shorter Pre-Communion Prayers
For those who cannot read the full canon due to time constraints, illness, or other circumstances, the Church also provides a shorter set of pre-communion prayers that can be said right before approaching the Chalice .
The Prayer of St. John Chrysostom
I believe, O Lord, and I confess that Thou art truly the Christ, the Son of the living God, Who camest into the world to save sinners, of whom I am first. I believe also that this is truly Thine immaculate Body, and that this is truly Thy precious Blood. Wherefore I pray Thee: have mercy upon me and forgive me my transgressions, voluntary and involuntary, in word and deed, known and unknown. And vouchsafe me without condemnation to partake of Thy immaculate Mysteries, unto remission of sins and unto life everlasting. Amen.
The Prayer Before Communion
Of Thy Mystical Supper, O Son of God, receive me today as a communicant; for I will not speak of Thy Mystery to Thine enemies, neither will I give Thee a kiss as did Judas; but like the thief will I confess Thee: Remember me, O Lord, in Thy Kingdom.
The Prayer of St. Simeon Metaphrastes
Create in me a clean heart, O God, and renew a right spirit within me. Cast me not away from Thy presence, and take not Thy Holy Spirit from me. Restore unto me the joy of Thy salvation, and with Thy governing Spirit establish me.
Practical Steps for Receiving Holy Communion
The Night Before
-
Read the Canon of Preparation (the full pre-communion prayer rule) or as much as you are able.
-
Fast from all food and drink after midnight (or from the time you go to bed)Â .
-
In some Orthodox homes, family members ask each other’s forgiveness the night before Communion.
The Morning of Liturgy
-
Continue the fast—nothing to eat or drink.
-
If you have not done so already, read the shorter pre-communion prayers.
-
Arrive at church on time. The general expectation is to be present before the Gospel reading, not to arrive at the Cherubic Hymn or later.
During the Divine Liturgy
-
Pray attentively throughout the service. The Liturgy itself is part of your preparation.
-
When it is time to receive, approach the Chalice with your arms crossed over your chest (right over left).
-
State your baptismal name clearly so the priest can say it as he gives you Communion.
-
Do not make the sign of the cross immediately before receiving, as you might bump the Chalice.
-
Open your mouth wide enough for the priest to place the Gifts without touching your teeth.
After Receiving Communion
-
Go directly to the table for the antidoron (blessed bread) and warm water (zaplivka) to help you swallow.
-
Return to your place and continue praying. This is not the time to chat or check your phone.
-
Remain in church until the service ends and the Cross is brought out for veneration.
After the Liturgy
-
Read the Prayers of Thanksgiving after Holy Communion, which can be found in most Orthodox prayer books.
-
Keep the remainder of the day as a feast. Try to avoid unnecessary distractions, idle chatter, and anything that would distract from the grace you have received.
Pastoral Guidance and Flexibility
The rules of preparation are meant to help you, not burden you. If you are a new Orthodox Christian, do not stress about getting everything perfect immediately. Talk to your priest about what is realistic for your situation.
Consider a young mother nursing a newborn. Her body is constantly giving. Sleep is broken. She may be unable to keep a strict food fast or read the entire canon. A rigid, one-size-fits-all approach would produce despair in that moment. It would turn the Christian life into a burden and present God as displeased by weakness. Yet Scripture reveals a different God: the One who receives the weary and heavy laden (Matthew 11:28).
This is why the Church insists on the importance of a spiritual father. A spiritual father is called to take the general therapeutic life of the Church—prayer, fasting, repentance, preparation for Communion—and help apply it to the actual person standing in front of him, with their concrete strengths and weaknesses, their physical condition, their psychological burden, their family situation, and their level of spiritual maturity.
If you cannot do the full rule, do what you can. Pray the shorter prayers. God knows your situation. That said, do not use busyness as an excuse to skip preparation entirely. If you are receiving the Body and Blood of Christ, you should do something to ready yourself. Even ten minutes with the shorter prayers is better than rolling in unprepared.

Conclusion
Preparing to receive Holy Communion is not about checking boxes on a spiritual to-do list. It is about readying your heart to receive the King of all. The Orthodox prayers before Communion are a gift from the Church to help you do just that. They guide you through repentance, confession of faith, and petitions for mercy. They remind you of your unworthiness without letting that unworthiness keep you away.
The pre-communion prayers are not meant to terrify you. They are meant to prepare you. They acknowledge that we are all unworthy of receiving Christ, yet they cry out for mercy anyway. The publican, the thief on the cross, the woman with the flow of blood—all approached Christ with nothing but desperation and faith, and all were received. You will be received as well.
Talk to your priest about your prayer rule, your fasting, and your confession schedule. He will help you figure out what is realistic for your life. A parent with three young children is not going to have the same prayer rule as a retired widower. The Church is pastoral, not legalistic. But she does have standards, and those standards exist because what happens at that Chalice matters more than anything else in your life .
When you approach the Chalice, you are not receiving a symbol. You are not receiving a memorial. You are receiving the actual Body and Blood of Jesus Christ—the Second Person of the Holy Trinity, the Savior of the world, the Lover of mankind. That reality should shape everything about how you prepare.
May the Lord make you worthy to partake of His Holy Mysteries for the remission of sins and for life everlasting. Amen.
