NIV 1 Corinthians 11:
3 But I want you to realize that the head of every man is Christ, and the head of the woman is man, and the head of Christ is God. 4Every man who prays or prophesies with his head covered dishonors his head. 5But every woman who prays or prophesies with her head uncovered dishonors her head—it is the same as having her head shaved. 6For if a woman does not cover her head, she might as well have her hair cut off; but if it is a disgrace for a woman to have her hair cut off or her head shaved, then she should cover her head.
7 A man ought not to cover his head, since he is the image and glory of God; but woman is the glory of man. 8For man did not come from woman, but woman from man; 9neither was man created for woman, but woman for man. 10 It is for this reason that a woman ought to have authority over her own head, because of the angels.
Does this mean that angels observe our church meetings?
Luke 15:10
In the same way, I tell you, there is rejoicing in the presence of the angels of God over one sinner who repents.
