Prayer of St. Thomas Aquinas before Holy Communion.
Almighty, everlasting God, I draw near to the sacrament of your only -begotten Son, our Lord Jesus Christ. I who am sick approach the physician of life. I who am unclean come to the fountain of mercy; blind, to the light of eternal brightness; poor and needy, to the Lord of heaven and earth. Therefore, I implore you, in your boundless mercy, to heal my sickness, cleanse my defilement, enlighten my blindness, enrich my poverty, and clothe my nakedness. Then shall I dare to receive the bread of Angles, the King of kings and Lord of lords, with reverence and humility, contrition and love, purity and faith, with the purpose and intention necessary for the good of my soul. Grant, I beseech you, that I may receive not only the Body and Blood of the Lord, but also the grace and power of the sacrament.
Most merciful God, enable me so to receive the Body of your only-begotten Son, our Lord Jesus Christ, which he took from the Virgin Mary, that I may be found worthy to be incorporated into his mystical Body, and counted among his members.
Most loving Father, grant that I may one day see face to face your beloved Son, whom I now intended to receive under the veil of the sacrament, and who with you and the Holy Spirit, lives and reigns for ever, one God, world without end. Amen.
Prayer of St. Ambrose before Holy Communion.
Lord, Jesus Christ, I approach your banquet table in fear and trembling, for I am a sinner, and dare not rely on my own worth but only on your goodness and mercy. I am defiled by many sins in body and soul, and by my unguarded thoughts and words. Gracious God of majesty and awe, I seek your protection, I look for your healing, poor troubled sinner that I am, I appeal to you, the fountain of all mercy. I cannot bear your judgment, but I trust in your salvation. Lord, I show my wounds to you and uncover my shame before you. I know my sins are many and great, and they fill me with fear, but I hope in your mercies, for they cannot be numbered.
Lord Jesus Christ, eternal King, God and man, crucified for mankind, look upon me with mercy and hear my prayer, for I trust in you. Have mercy on me, full of sorrow and sin, for the depth of your compassion never ends. Praise to you, saving sacrifice, offered on the wood of the cross for me and for all mankind. Praise to the noble and precious blood, flowing from the wounds of my crucified Lord Jesus Christ and washing away the sins of the whole world. Remember, Lord, your creature, whom you have redeemed with your blood. I repent my sins, and I long to put right what I have done.
Merciful Father, take away all my offenses and sins; purify me in body and soul, and make me worthy to taste the holy of holies. May Your Body and Blood, which I intend to receive, although I am unworthy, be for me the remission of my sins, the washing away of my guilt, the end of my evil thoughts, and the rebirth of my better instincts. May it incite me to do the works pleasing to you and profitable to my health in body and soul, and be a firm defense against the wiles of my enemies. Amen.
Prayer of Padre Pio after Holy Communion
Stay with me, Lord, for it is necessary to have You present so that I do not forget You.
You know how easily I abandon You.
Stay with me, Lord, because I am weak and I need Your strength, that I may not fall so often.
Stay with me, Lord, for You are my life and without You I am without fervor.
Stay with me, Lord, for You are my light and without You I am in darkness.
Stay with me, Lord, to show me Your will.
Stay with me, Lord, so that I hear Your voice and follow You.
Stay with me, Lord, for I desire to love You very much and always be in Your company.
Stay with me, Lord, if You wish me to be faithful to You.
Stay with me, Lord, as poor as my soul is I want it to be a place of consolation for You, a nest of Love.
Stay with me, Jesus, for it is getting late and the day is coming to a close and life passes, death, judgment and eternity approaches. It is necessary to renew my strength, so that I will not stop along the way and for that, I need You. It is getting late and death approaches, I fear the darkness, the temptations, the dryness, the cross, the sorrows. O how I need You, my Jesus, in this night of exile!
Stay with me tonight, Jesus, in life with all its dangers, I need You.
Let me recognize You as Your disciples did at the breaking of the bread, so that the Eucharistic Communion be the Light which disperses the darkness, the force which sustains me, the unique joy of my heart.
Stay with me, Lord, because at the hour of my death, I want to remain united to You, if not by Communion, at least by grace and love.
Stay with me, Lord, for it is You alone I look for, Your Love, Your Grace, Your Will, Your Heart, Your Spirit, because I love You and ask no other reward but to love You more and more.
With a firm love, I will love You with all my heart while on earth and continue to love You perfectly during all eternity. Amen.
Prayer of St. Basil the Great after Holy Communion
O Christ, our Master and God, King of the ages and Creator of all, I thank You for all the Good things that You have given to me and for the reception of Your most pure and life-giving Mysteries.
I pray You, therefore, O good Lover of mankind, keep me under Your protection in the shadow of Your wings.
Grant that with a pure conscience, until my last breath, I may worthily partake of Your Holy Things, for the forgiveness of sins and for life everlasting.
For You are the bread of Life, the Fountain of holiness, and the Bestower of blessings, and to You we give glory together with the Father and the Holy Spirit, now and for ever and ever. Amen.

Prayer of St. John Damascene after Holy Communion
God, my God, unextinguishable and invisible fire, You make Your angels flaming fire.
Out of Your inexpressible love You have given me Your divine Flesh as food, and through this communion of Your immaculate Body and precious Blood You receive me as a partaker of Your divinity.
Permeate all my body and soul, all my bones and sinews.
Consume my sins in fire.
Enlighten my soul and illumine my mind.
Sanctify my body and make Your abode in me together with Your blessed Father and all-holy Spirit, that I may always abide in You, through the intercession of Your immaculate Mother and all Your saints. Amen.
