Before Communion:
Almighty and everlasting God, behold, I am about to approach the Sacrament of Thine only-begotten Son, our Lord Jesus Christ. I approach as one who is sick to the physician of life, as one unclean to the well-spring of mercy and goodness, as one blind to the light of eternal brightness, as one poor and needy to the Lord of heaven and earth. Wherefore I beseech Thee, of Thine infinite goodness, to heal my sickness, to wash away my filth, to enlighten my blindness, to enrich my poverty, and to clothe my nakedness, that I may receive the Bread of Angels, the King of kings, and Lord of lords with such reverence, and humility, with such contrition and devotion, with such purity and faith, with such purpose and intention, as may conduce to the salvation of my soul.
Grant, I beseech Thee, that I may receive not only the Sacrament of the Body and Blood of our Lord, but also the fruit and virtue of the Sacrament. O most indulgent and merciful God, grant me so to receive the Body of Thine only-begotten Son, our Lord Jesus Christ, which He took of the Virgin Mary, that I may be found worthy to be incorporated with His mystical body and numbered among His members. O most loving Father, grant that I may one day contemplate for ever dace to face Thy beloved Son, whom now on my pilgrimage I am about to receive under a veil, who liveth and reigneth with Thee in the unity of the Holy Ghost, God, for ever and ever. Amen.
After Communion:
I give thanks to Thee, O holy Lord, Father almighty, eternal God, who hast vouchsafed, not for any merits of my own, but solely out of the condescension of Thy mercy, to appease the hunger of the soul of Thine unworthy servant, with the precious Body and Blood of Thy Son, our Lord Jesus Christ. I implore that this holy Communion be not to me a condemnation unto punishment, but a saving plea unto forgiveness. May it be unto me the armour of faith and the shield of good purpose. May it be the emptying out of my vices, the extinction of all concupiscence and lust, the increase of charity and patience, of humility and obedience, and of all virtues; a strong defense against the snares of all enemies, visible and invisible; the prefect quieting of all my impulses, both fleshly and ghostly; a firm cleaving unto Thee, the one true God; and an earnest pledge of a happy consummation. And I beseech Thee, that Thou wouldst vouchsafe to bring me, a sinner, to that ineffable Banquet, in which Thou, together with Thy Son, and the Holy Ghost, art to the Thy Saints true light, fullness of content, eternal joy, gladness without alloy and perfect happiness. Through the same Christ our Lord. Amen.
