1 Corinthians 11
27 Ref 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.
28 Ref But let no man take of the bread and the cup without testing himself.
29 Ref 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.
30 Ref For this cause a number of you are feeble and ill, and a number are dead.
