1 Korintus 10:16-17

10:16 Is not the cup of blessing that we bless a sharing in the blood of Christ? Is not the bread that we break a sharing in the body of Christ? 10:17 Because there is one bread, we who are many are one body, for we all share the one bread.

1 Korintus 11:24-25

11:24 and after he had given thanks he broke it and said, “This is my body, which is for you. Do this in remembrance of me.” 11:25 In the same way, he also took the cup after supper, saying, “This cup is the new covenant in my blood. Do this, every time you drink it, in remembrance of me.”
