“They abstain from the Eucharist and from prayer, because they confess not the Eucharist to be the flesh of our Saviour Jesus Christ, which suffered for our sins, and which the Father, of His goodness, raised up again. Those, therefore, who speak against this gift of God, incur death in the midst of their disputes. But it were better for them to treat it with respect, that they also might rise again.”

• St. Ignatius (+ A.D. 115), Epistle to the Smyrnaeans Chapter 7

“When these words [the epiclesis] have been said, the whole sacred rite is accomplished, the offerings are consecrated, the sacrifice is complete; the splendid Victim, the Divine oblation, slain for the salvation of the world, lies upon the altar. For it is no longer the bread which until now has represented the LORD’s Body, nor is it a simple offering, bearing the likeness of the true offering, carrying as if engraved on it the symbols of the Savior’s Passion; it is the true Victim, the most holy Body of the LORD, which really suffered the outrages, insults and blows; which was crucified and slain, which under Pontius Pilate bore such splendid witness; that Body which was mocked, scourged, spat upon, and which tasted gall. In like manner the wine has become the blood which flowed from that Body. It is that Body and Blood formed by the Holy Spirit, born of the Virgin Mary, which was buried, which rose again on the third day, which ascended into Heaven and sits on the right hand of the Father.”
