1 Corinthians 11:28-34

28Each one must examine himself before he eats of the bread and drinks of the cup. 29For anyone who eats and drinks without recognizing the body1 eats and drinks judgment on himself. 30That is why many among you are weak and sick, and a number of you have fallen asleep.

31Now if we judged ourselves properly, we would not come under judgment. 32But when we are judged by the Lord, we are being disciplined so that we will not be condemned with the world.

33So, my brothers, when you come together to eat, wait for one another. 34If anyone is hungry, he should eat at home, so that when you come together it will not result in judgment. And when I come, I will give instructions about the remaining matters.
