Likewise also the cup after supper, saying,
This cup is the new covenant in my blood, which is shed for you.
All Commentaries on Luke 22:20 Go To Luke 22
Cyril of Alexandria
AD 444
By uniting flesh that was subject to death to himself, the Word being God and life drove corruption away from it. Christ also made it to be the source of life. The body of him who is the life must be this.Do not doubt what I have said but rather accept the word in faith, having gathered proofs from a few examples. When you place a piece of bread into wine, oil, or any other liquid, you find that it becomes charged with the quality of that particular thing. When iron is brought into contact with fire, it becomes full of its activity. While it is by nature iron, it exerts the power of fire. The lifegiving Word of God, having united himself to his own flesh in a way known to himself, likewise endowed it with the power of giving life…. When we eat the holy flesh of Christ, the Savior of us all, and drink his precious blood, we have life in us. We are made one with him, abide in him, and possess him in us. Commentary on Luke, Homily
