Thanks giving prayer after Mass by angelic doctor St. Thomas Aquinas

I thank you, holy Lord, almighty Father, eternal God, who deigned to feast me, sinful and unworthy servant, with the precious body and blood of your Son, Jesus Christ our Lord, not for any merit of mine, but only because of your merciful goodness. And I pray that this Holy Communion, far from condemning me to punishment, may bring about my pardon and salvation, encompassing me with the armor of faith and the shield of a good will. By it let my vices be done away, all lustful desires extinguished. May it advance me in charity, patience, humility, obedience, and every other virtue. Let it be strong defense against the wiles of all my enemies, visible and invisible, allaying for me every disturbance of flesh and spirit, binding me firmly to you, the one true God, and bringing my last hour to a happy close. I pray, too, that it may be your pleasure to call my sinful self one day to that banquet, wonderful past all telling, where you, with your Son and the Holy Spirit, feast your saints with the vision of yourself, who are true light, the fulfillment of all desires, the joy that knows no ending, gladness unalloyed, and perfect bliss: through the same Christ our Lord. Amen.
