Prayer of St. Ambrose (Before Mass)
I draw near to the table of your most delectable banquet, dear Lord Jesus Christ. A sinner, I trust not in my own merit; but, in fear and trembling, I rely on your mercy and goodness. I have a heart and body marked by my grave offenses, and a mind and a tongue I have not guarded well. For this reason, God of loving kindness and awesome majesty, I, a sinner caught by many snares, seek safe refuge in you. For you are the fountain of mercy.
I would fear to draw near to you as my judge, but I seek you out as my Savior. Lord, I show you my wounds, and I let you see my shame. Knowing my sins are many and great, I have reason to fear. But I trust in your mercies, for they are beyond all numbering.
Look upon me with mercy, for I trust in you, my Lord Jesus Christ, eternal king, God and man, you who were crucified for mankind. Have mercy upon me, you who never cease to make the fountain of your mercy flow, for I am full of sorrows and sins.
I praise you, the saving Victim offered on the wood of the cross for me and for all mankind. I praise the noble Blood that flows from the wounds of my Lord Jesus Christ, the precious Blood that washes away the sins of all the world.
Remember, Lord, your creature, whom you have redeemed with your own Blood. I am sorry that I have sinned, and I long to put right what I have done. Most kind Father, take away all my offenses and sins, so that, purified in body and soul, I may be made worthy to taste the Holy of holies.
And grant that this holy meal of your Body and Blood, which I intend to take, although I am unworthy, may bring forgiveness of my sins and wash away my guilt. May it mean the end of my evil thoughts and the rebirth of my better longings. May it lead me securely to live in ways that please you, and may it be a strong protection for body and soul, against the plots of my enemies. Amen.
Prayer of St. Thomas Aquinas (Before Mass)
Almighty and ever-living God, I draw near to the sacrament of your only-begotten Son, our Lord Jesus Christ.
I come sick to the physician of life, unclean to the fountain of mercy, blind to the light of eternal brightness, poor and needy to the Lord of heaven and earth.
So I ask you, most generous Lord: graciously heal my infirmity, wash me clean, illumine my blindness, enrich my poverty, and clothe my nakedness.
May I receive the Bread of angels, the King of kings, and Lord of lords, with such reverence and humility, such contrition and devotion, such purity and faith, and such resolve and determination as may secure my soul's salvation. Grant as I may receive not only the visible sign of the Lord's Body and Blood, but also all the reality and the power of the sacrament.
Grant most kind God, that I may receive the Body of your only-begotten Son, our Lord Jesus Christ, which he received from the Virgin Mary, and may receive it in such a way that I become a loving part of his Mystical Body and counted among his members.
O most loving Father, grant me your beloved Son.
While on this earthly pilgrimage, I receive him under the veil of this sacrament; so may I come at last to see him face to face for all eternity. For he lives and reigns with you for ever and ever. Amen.
Prayer of St. John Chrysostom (Before Mass)
I believe, O Lord, and I confess that Thou art truly the Christ, the Son of the Living God, Who came into the world to save sinners, of whom I am the chief.
And I believe that this is Thy pure Body and Thy own precious Blood. Therefore, I pray Thee, have mercy on me and forgive my transgressions, voluntary and involuntary, in word and deed, known and unknown.
And grant that I may partake of Thy Holy Mysteries without condemnation, for the remission of sins and for life eternal. Amen.
Prayer of St. Thomas Aquinas (After Mass)
Lord, Father all-powerful and ever-living God, I thank you, for even though I am a sinner, your unprofitable servant, not because of my worth but in the kindness of your mercy, you have fed me with the precious body and blood of your Son, our Lord Jesus Christ. I pray that this holy communion may not bring me condemnation and punishment but forgiveness and salvation.
May it be a helmet of faith and a shield of good will. May it purify me from evil ways and put an end to my evil passions. May it bring me charity and patience, humility and obedience, and growth in the power to do good. May it be my strong defense against all my enemies, visible and invisible, and the perfect calming of all my evil impulses, bodily and spiritual.
May it unite me more closely to you, the one true God, and lead me safely through death to everlasting happiness with you. And I pray that you will lead me, a sinner, to the banquet where you, with your Son and Holy Spirit, are true and perfect light, total fulfillment, everlasting joy, gladness without end, and perfect happiness to your saints. Grant this through Christ our Lord. Amen.
Soul of Christ, sanctify me.
Body of Christ, save me.
Blood of Christ, inebriate me.
Water from the side of Christ, wash me.
Passion of Christ, strengthen me.
O good Jesus, hear me.
Within Your wounds, hide me.
Separated from you, let me never be.
From evil one, protect me.
At the hour of my death, call me.
and close to you, bid me.
That with your saints, I may be.
Praising you forever and ever. Amen.
