The apostle Paul tells us in 1 Corinthians 11:3–15:
But I want you to understand that the head of every man is Christ, the head of a wife1 is her husband, and the head of Christ is God. 4 Every man who prays or prophesies with his head covered dishonors his head, 5 but every wife2 who prays or prophesies with her head uncovered dishonors her head, since it is the same as if her head were shaven. 6 For if a wife will not cover her head, then she should cut her hair short. But since it is disgraceful for a wife to cut off her hair or shave her head, let her cover her head. 7 For a man ought not to cover his head, since he is the image and glory of God, but woman is the glory of man. 8 For man was not made from woman, but woman from man. 9 Neither was man created for woman, but woman for man. 10 That is why a wife ought to have a symbol of authority on her head, because of the angels.3 11 Nevertheless, in the Lord woman is not independent of man nor man of woman; 12 for as woman was made from man, so man is now born of woman. And all things are from God. 13 Judge for yourselves: is it proper for a wife to pray to God with her head uncovered? 14 Does not nature itself teach you that if a man wears long hair it is a disgrace for him, 15 but if a woman has long hair, it is her glory? For her hair is given to her for a covering.
There we have it, in plain text from the mouth of God to the hand of Paul!
While hair length is not the main point of this passage of scripture, we glean the following applications from it. 1) We should adhere to the culturally accepted indicators of gender. Men should look like men, and women should look like women. God is not interested in, nor does He accept, “unisex.” 2) We should not rebel against the culture just for the sake of rebelling, in the name of some sort of Christian “liberty.” It does matter how we present ourselves. 3) Women are to voluntarily place themselves under the authority of men in the church. 4) We should not reverse the God-ordained roles of men and women.To me the sight of a woman’s ears, especially aged women who know better is a horrible insult to God. I hope you agree.
