1 Corinthians 11:27-34 - Self-Examination
27 Therefore, whoever eats the bread or drinks the cup of the Lord in an unworthy way will be guilty of sin against the body
33 Therefore, my brothers, when you come together to eat, wait for one another. 34 If anyone is hungry, he should eat at home, so that when you gather together you will not come under judgment. And I will give instructions about the other matters whenever I come.
