And he took bread, and gave thanks, and broke it, and gave unto them, saying,
This is my body which is given for you: this do in remembrance of me.

Cyril of Alexandria
AD 444
Nor doubt that this is true; for He plainly says, This is my body; but rather receive the words of your Savior in faith. For since He is the Truth, He lies not. They rave foolishly then who say that the mystical blessing loses its power of sanctifying, if any remains are left till the following day. For the most holy Body of Christ will not be changed, but the power of blessing and the life giving grace is ever abiding in it. For the life-giving power of God the Father is the only-begotten Word, which was made flesh not ceasing to be the Word, but making the flesh life giving. What then? since we have in us the life of God, the Word of God dwelling in us, will our body be life-giving? But it is one thing for us by the habit of participation to have in ourselves the Son of God, another for Himself to have been made flesh, that is, to have made the body which He took from the pure Virgin His own Body. He must needs then be in a certain manner united to our bodies by His holy Body and precious Blood, which we have received for a life giving blessing in the bread and wine. For lest we should be shocked, seeing the Flesh and Blood placed on the holy altars, God, in compassion to our infirmities, pours into the offerings the power of life, changing them into the reality of His own flesh, that the body of life may be found in us, as it were a certain life-giving seed. He adds, Do this in commemoration of me.
