1 Corinthians 11:5 (alternate reading because of the heads of verse 3) But every woman that prayeth or prophesieth with her man/husband uncovered dishonoureth her man/husband: for that is even all one as if she were shaven. This idea of the woman uncovering her man/husband is as described, the same as if she was shaved. If a woman was caught in adultery or pros***ution, her head, body part was shaved. This was to identify her, to her shame, that she was an adulteress or a pros***ute. Having her head, body part shaved would leave her man/husband uncovered and open to the shame of being married to an adulteress or a pros***ute.
1 Corinthians 11:6 is speaking of a woman not being covered and departs from verse 3 because verse 3 does not mention a woman as a head or if she should be covered or uncovered. Verse 6 does relate to verse 5 as it is a continuation of the explanation of how a woman uncovers her head, man/husband. If a woman doesn’t wear a vail then let her be shorn. If she wants to go without a vail she can also be shorn. The problem only arises if to be shaved or shorn is a shame such as identifying as an adulteress or a pros***ute. If it is a shame then let her wear a vail.
1 Corinthians 11:7 (alternate reading because of the heads of verse 3) For a man indeed ought not to cover Christ, forasmuch as Christ is the image and glory of God: (See Hebrews 1:3) but the woman is the glory of the man. The man’s head, Christ, is not covered because Christ is the image and glory of God. The man/husband should be covered by the woman because she is the glory of the man.
The rest of the verses that you have listed are speaking of the nature of men and women in order to show the reason for the woman to cover her head, man/husband. As I see it and hopefully explained, there is no reason to think that this has anything to do with the length of a man or woman’s hair.
I do hope that I am not wearing you out on this subject.
