1 Corinthians 11:29-32

29For those who eat and drink without discerning the body of Christ eat and drink judgment on themselves.

30That is why many among you are weak and sick, and a number of you have fallen asleep.

31But if we were more discerning with regard to ourselves, we would not come under such judgment.

32Nevertheless, when we are judged in this way by the Lord, we are being disciplined so that we will not be finally condemned with the world.
