1 Coríntios 11:23-30 - Bíblia Online

For it was handed down to me from the Lord, as I gave it to you, that the Lord Jesus, on the night when Judas was false to him, took bread, 
And when it had been broken with an act of praise, he said, This is my body which is for you: do this in memory of me. 
In the same way, with the cup, after the meal, he said, This cup is the new testament in my blood: do this, whenever you take it, in memory of me. 
For whenever you take the bread and the cup you give witness to the Lord's death till he comes. 
If, then, anyone takes the bread or the cup of the Lord in the wrong spirit, he will be responsible for the body and blood of the Lord. 
But let no man take of the bread and the cup without testing himself. 
For a man puts himself in danger, if he takes part in the holy meal without being conscious that it is the Lord's body. 
For this cause a number of you are feeble and ill, and a number are dead.
