*Bold in the verses are my emphasis
1 Corinthians 11:3-7 "But I would have you know, that the head of every man is Christ; and the head of the woman is the man; and the head of Christ is God. Every man praying or prophesying, having his head (Christ) covered, dishonoureth his head (Christ). But every woman that prayeth or prophesieth with her head (man) uncovered dishonoureth her head (man): for that is even all one as if she were shaven. For if the woman be not covered, let her also be shorn: but if it be a shame for a woman to be shorn or shaven, let her be covered. For a man indeed ought not to cover his head (Christ), forasmuch as he is the image and glory of God: but the woman is the glory of the man."
While this text can be confusing at first, when looked at in context, it isn't. To define the head of the man and the head of the woman, look at verse 3. While there are comparisons to a woman with a shaved head, that appears to be a metaphor for something greater.
1 Corinthians 11:14-16 "Doth not even nature itself teach you, that, if a man have long hair, it is a shame unto him? But if a woman have long hair, it is a glory to her: for her hair is given her for a covering. But if any man seem to be contentious, we have no such custom, neither the churches of God."
Why would Paul say such things regarding the length of hair? Given the context of the chapter, it appears that something more important is being taught. Here man should have his head uncovered while praying/prophesying, and should not have long hair. A woman should have her head covered while praying/prophesying, and should have long hair. It appears that the length of hair is a representation of the the position of man/woman in relation to God.
1. God
2. Christ
3. Man
4. Woman
Interesting subject when looked at in-depth.
