ACC ~ 1 Corinthians 11 v24

THE WORDS OF CONSECRATION OF THE EUCHARIST. AMBROSE: Do you wish to know how it is consecrated with heavenly words? Accept what the words are. The priest speaks. He says: Perform for us this oblation written, reasonable, acceptable, which is a figure of the body and blood of our Lord Jesus Christ. … Before it is consecrated, it is bread; but when Christ’s words have been added, it is the body of Christ. … And before the words of Christ, the chalice is full of wine and water. When the words of Christ have been added, then blood is effected which redeemed the people. THE SACRAMENTS 4.5.21-23.

FULL ASSURANCE OF THE DIVINE MYSTERIES. CYRIL OF JERUSALEM: The teaching of the blessed Paul is of itself sufficient to give you full assurance about the divine mysteries by admission to which you have become one body and blood with Christ. … When the Master himself has explicitly said of the bread, “This is my body,” will anyone still dare to doubt? When he is himself our warranty saying, “This is my blood,” who will ever waver and say it is not his blood? … With perfect confidence, then, we partake as of the body and blood of Christ. ON THE MYSTERIES, FOURTH LECTURE 1.2.

A SACRIFICE OF THANKSGIVING. CHRYSOSTOM: Paul reminds us that the Master gave up everything, including himself, for us, whereas we are reluctant even to share a little food with our fellow believers. But if you come for a sacrifice of thanksgiving, do not do anything unworthy of that sacrifice. Do not dishonor your brothers or neglect them in their hunger, do not get drunk, and do not insult the church. When you come, give thanks for what you have enjoyed, and do not cut yourselves off from your neighbors. HOMILIES ON THE EPISTLES OF PAUL TO THE CORINTHIANS 27.5.

IN REMEMBRANCE OF ME. PELAGIUS: In blessing the bread even before his suffering, Jesus left behind a last commemoration, or memorial. This is rather like someone who, when about to go on a journey, leaves some token of himself with his loved one, so that whenever she looks at it she will be reminded of his goodness and love toward her.
