Prayers Before Receiving Communion
Prayer of St. John of Damascus
Master and Lord, Jesus Christ our God, You alone have authority to forgive my sins, whether committed knowingly or in ignorance, and make me worthy to receive without condemnation Your divine, glorious, pure and life-giving Mysteries, not for my punishment, but for my purification and sanctification, now and in Your future Kingdom. For You, Christ our God are compassionate and love mankind and to You we give glory with the Father and the Holy Spirit now and forever and ever. Amen.
Prayers Right Before Communion
I believe and confess, Lord, that You are truly the Christ, the Son of the living God, who came into the world to save sinners, of whom I am the first. I also believe that this is truly Your pure Body and that this is truly Your precious Blood. Therefore, I pray to You, have mercy upon me, and forgive my transgressions, voluntary and involuntary, in word and deed, known and unknown. And make me worthy without condemnation to partake of Your pure Mysteries for the forgiveness of sins and for eternal life. Amen
How shall I, who am unworthy, enter into the splendor of Your saints? If I dare to enter into the bridal chamber, my clothing will accuse me, since it is not a wedding garment; and being bound up, I shall be cast out by the angels. In Your love, Lord, cleanse my soul and save me.
Loving Master, Lord Jesus Christ, my God, let not these holy Gifts be to my condemnation because of my unworthiness, but for the cleansing and sanctification of soul and body and the pledge of the future life and kingdom. It is good for me to cling to God and to place in Him the hope of my salvation.
Receive me today, Son of God, as a partaker of Your mystical Supper. I will not reveal Your mystery to Your adversaries. Nor will I give You a kiss as did Judas. But as the thief I confess to You: Lord, remember me in Your Kingdom.
Prayers After Receiving Communion
Lord Jesus Christ, my God, now that I have received Your holy Body and Blood, grant me forgiveness of my sins and life everlasting.
I thank You, loving Master, benefactor of my soul, that on this day You have again made me worthy of Your heavenly and immortal mysteries. Direct my way on the right path. Establish me firmly in Your fear. Guard my life. And make my endeavors safe, through the prayers of the glorious Theotokos and ever-virgin Mary and of all Your Saints. Amen.
Lord Jesus Christ my God, let Your sacred Body be unto me for eternal life and Your precious Blood for forgiveness of sins. Let this Eucharist be unto me for joy, health and gladness. And in Your awesome Second Coming make me, a sinner, worthy to stand at the right hand of Your glory; through the intercessions of Your pure Mother and of all Your Saints. Amen.
