1 Coríntios 11:23-30 - Bíblia Online

For I passed on to you the account, which I myself received from the Lord; how the Lord Jesus, on the very night he was betrayed, took bread, 
and when he had given thanks, he broke it, saying, "This is my body, broken for you; this do in memory of me." 
In the same way also, he took the cup after supper, saying. "This cup is the new covenant in my blood; do this, whenever you drink it, in memory of me." 
For as often as you eat this bread and drink this cup, you are proclaiming your Lords death until he come. 
So he that eats the bread or drinks the cup of the Lord unworthy must answer for a sin against the body and blood of the Lord. 
Let each man scrutinize himself, and thus let him eat of the bread and drink of the cup. 
For whoever eats and drinks without discerning the body, eats and drinks condemnation to himself. 
This is why many among you are feeble and sickly, and many sleep.
