6:51I am the living bread which came down from heaven: if any man eat of this bread, he shall live for ever: and the bread that I will give is my flesh, which I will give for the life of the world.
6:56He that eateth my flesh, and drinketh my blood, dwelleth in me, and I in him.
10:16The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ?
11:26For as often as ye eat this bread, and drink this cup, ye do shew the Lord's death till he come.
3:27For as many of you as have been baptized into Christ have put on Christ.
