"This food we call the Eucharist, of which no one is allowed to partake except one who believes that the things we teach are true, and has received the washing for forgiveness of sins and for rebirth, and who lives as Christ handed down to us. For we do not receive these things as common bread or common drink; but as Jesus Christ our Savior being incarnate by God's Word took flesh and blood for our salvation, so also we have been taught that the food consecrated by the Word of prayer which comes from him, from which our flesh and blood are nourished by transformation, is the flesh and blood of that incarnate Jesus."
"First Apology", Ch. 66, inter A.D. 148-155.
"God has therefore announced in advance that all the sacrifices offered in His name, which Jesus Christ offered, that is, in the Eucharist of the Bread and of the Chalice, which are offered by us Christians in every part of the world, are pleasing to Him."
"Dialogue with Trypho", Ch. 117, circa 130-160 A.D.
Moreover, as I said before, concerning the sacrifices which you at that time offered, God speaks through Malachias, one of the twelve, as follows: 'I have no pleasure in you, says the Lord; and I will not accept your sacrifices from your hands; for from the rising of the sun until its setting, my name has been glorified among the gentiles; and in every place incense is offered to my name, and a clean offering: for great is my name among the gentiles, says the Lord; but you profane it.' It is of the sacrifices offered to Him in every place by us, the gentiles, that is, of the Bread of the Eucharist and likewise of the cup of the Eucharist, that He speaks at that time; and He says that we glorify His name, while you profane it."
-"Dialogue with Trypho", [41: 8-10]
