Ambrose of Milan — as excerpted in the Catena Aurea on Matthew 26:26

“(de Sacr. iv. 3.) Hence learn that the Christian mysteries were before the Jewish. Melchisedech offered bread and wine, being in all things like the Son of God, (Ps. 110:4.) to Whom it is said, Thou art a Priest for ever after the order of Melchisedech; and of Whom it is here said, Jesus took bread. (John 12:24.)”
