1 Corinthians 11:20

Overview - 1 Corinthians 11
He reproves them, because in holy assemblies,
their men prayed with their heads covered,
and women with their heads uncovered;
17 and because generally their meetings were not for the better, but for the worse;
21 as, namely, in profaning with their own feast the Lord's supper.
25 Lastly, he calls them to the first institution thereof.
