1 Coríntios 11

24 and after giving thanks He broke it and said, »This is my body which is about to be broken for you. Do this in memory of me.«

25 In the same way, when the meal was over, He also took the cup. »This cup,« He said, »is the new Covenant of which my blood is the pledge. Do this, every time that you drink it, in memory of me.«

26 For every time that you eat this bread and drink from the cup, you are proclaiming the Lord's death–until He returns.

27 Whoever, therefore, in an unworthy manner, eats the bread or drinks from the cup of the Lord sins against the body and blood of the Lord.

28 But let a man examine himself, and, having done that, then let him eat the bread and drink from the cup.
