1 Coríntios 11:23-30 - Bíblia Online

For I received from the Lord what I also delivered to you, that the Lord Jesus in the night in which he was betrayed took bread, 
and having expressed thanks, he broke in pieces, and said, Take ye, eat, this is my body broken for you. This do ye for my memorial. 
Likewise also the cup after the supper, saying, This cup is the new covenant in my blood. This do, as often as ye drink it, for my memorial. 
For as often as ye eat this bread and drink this cup, ye proclaim the Lord's death until he comes. 
Therefore whoever may eat this bread or drink the cup of the Lord unworthily of the Lord, will be guilty of the body and the blood of the Lord. 
But let a man examine himself, and let him so eat of the bread, and drink of the cup. 
For he who eats and drinks unworthily, eats and drinks condemnation to himself, not discerning the body of the Lord. 
Because of this many are weak and sickly among you, and a considerable sleep.
