Theophylact of Ohrid
Catena Aurea · Lukasevangelium 22
And he took bread, and gave thanks, and brake it, and gave unto them, saying, This is my body which is given for you: this do in remembrance of me. Likewise also the cup after supper, saying, This cup is the new testament in my blood, which is shed for you.
Now Luke mentions two cups; of the one we spoke above, Take this, and divide it among yourselves, which we may say is a type of the Old Testament; but the other after the breaking and giving of bread, He Himself imparts to His disciples. Hence it is added, Likewise also the cup after supper.
