“When you see the Lord immolated and lying upon the altar, and the priest bent over that sacrifice praying, and all the people empurpled by that precious blood, can you think that you are still among men and on earth? Or are you not lifted up to heaven?” (The Priesthood 3:4:177 [A.D. 387]).
“Reverence, therefore, reverence this table, of which we are all communicants! Christ, slain for us, the sacrificial victim who is placed thereon!” (Homilies on Romans 8:8 [A.D. 391]).
“‘The cup of blessing which we bless, is it not communion of the blood of Christ?’ Very trustworthy and awesomely does he [Paul] say it. For what he is saying is this: What is in the cup is that which flowed from his side, and we partake of it. He called it a cup of blessing because when we hold it in our hands that is how we praise him in song, wondering and astonished at his indescribable gift, blessing him because of his having poured out this very gift so that we might not remain in error; and not only for his having poured it out, but also for his sharing it with all of us. ‘If therefore you desire blood,’ he [the Lord] says, ‘do not redden the platform of idols with the slaughter of dumb beasts, but my altar of sacrifice with my blood.’ What is more awesome than this? What, pray tell, more tenderly loving?” (Homilies on First Corinthians 24:1(3) [A.D. 392]).
“In ancient times, because men were very imperfect, God did not scorn to receive the blood which they were offering . . . to draw them away from those idols; and this very thing again was because of his indescribable, tender affection. But now he has transferred the priestly action to what is most awesome and magnificent. He has changed the sacrifice itself, and instead of the butchering of dumb beasts, he commands the offering up of himself” (ibid., 24:2).
“What then? Do we not offer daily? Yes, we offer, but making remembrance of his death; and this remembrance is one and not many. How is it one and not many? Because this sacrifice is offered once, like that in the Holy of Holies. This sacrifice is a type of that, and this remembrance a type of that. We offer always the same, not one sheep now and another tomorrow, but the same thing always. Thus there is one sacrifice. By this reasoning, since the sacrifice is offered everywhere, are there, then, a multiplicity of Christs? By no means! Christ is one everywhere. He is complete here, complete there, one body. And just as he is one body and not many though offered everywhere, so too is there one sacrifice” (Homilies on Hebrews 17:3(6) [A.D. 403]).
