Thanksgiving of St. Thomas Aquinas After Holy Communion

I give Thee thanks, O holy Lord, Father Almighty, Eternal God, who hast vouchsafed, not through any merits of mine, but out of the condescension of Thy pure mercy, to appease the hunger of my soul, a sinner and Thine unworthy servant, with the precious Body and Blood of Thy Son, our Lord Jesus Christ. And I pray that this Holy Communion may not be to me a ground for punishment, but a saving intercession for pardon. May it be to me an armor of faith and a shield of good will. May it be the casting out of my vices, the extinction of concupiscence and lust, the increase of charity and patience, of humility and obedience, and of all virtues; a firm defense against the snares of all my enemies, visible as well as invisible; the perfect quieting of all my evil impulses, carnal and spiritual; a firm cleaving unto Thee, the one true God; and a happy consummation of my end. And I pray Thee that Thou wouldst vouchsafe to bring me, a sinner, to that ineffable banquet where Thou, with Thy Son and the Holy Ghost, art to Thy Saints true light, full satiety, everlasting joy, consummate pleasure, and perfect happiness. Through the same Christ our Lord. Amen.
