And this food is called among us the Eucharist, of which it is lawful for no one to partake except the one who believes that the things we teach are true, and has been washed with the washing for the forgiveness of sins and unto regeneration, and so lives as Christ handed down. For we do not receive these things as common bread or common drink; but just as Jesus Christ our Savior, having been made flesh through the Word of God, took both flesh and blood for our salvation, so also we have been taught that the food over which thanks have been given through the prayer of the Word that comes from him—the food from which our blood and flesh are by transformation nourished—is both the flesh and the blood of that Jesus who was made flesh. For the apostles, in the memoirs made by them, which are called Gospels, handed down that it was thus enjoined upon them: that Jesus, having taken bread and given thanks, said, "Do this in remembrance of me; this is my body"; and that likewise, having taken the cup and given thanks, he said, "This is my blood"; and that he gave it to them alone. Which the wicked demons, in imitation, have handed down to be done also in the mysteries of Mithras; for that bread and a cup of water are set out in the rites of initiation, with certain formulas, you either know or are able to learn.
