1 Coríntios 11:23-30 - Bíblia Online

For I have received of the Lord that which also I delivered unto you, That the Lord Jesus the [same] night in which he was betrayed took bread; 
and when he had given thanks, he broke [it] and said, Take, eat: this is my body, which is broken for you; this do in remembrance of me. 
After the same manner also [he took] the cup, after he had eaten supper, saying, This cup is the new testament in my blood; do this each time that ye drink, in remembrance of me. 
For each time that ye eat this bread and drink this cup, ye declare the Lord's death until he comes. 
Therefore whoever shall eat this bread and drink [this] cup of the Lord unworthily shall be guilty of the body and blood of the Lord. 
But let each man prove himself, and so let him eat of the bread and drink of the cup. 
For he that eats and drinks unworthily, eats and drinks judgment to himself, not discerning the Lord's body. 
For this cause many [are] weak and sickly among you, and many sleep.
