Thomas Aquinas, on 1Cor 11:5

“But every woman praying or prophesying with her head not covered, disgraceth her head: for it is all one as if she were shaven.”

“Then when he says, but every woman, he gives an admonition as it applies to women, saying: But any woman who prays or prophesies with her head unveiled (which is unbecoming, considering her condition) disgraces her head, i.e., does something unsuitable in regard to covering her hair. But against this is the Apostle's statement in 1 Tim (2:12): "I permit no woman to teach in church." How, then, does it befit a woman to pray or prophesy in public prayer or in doctrine. The answer is that this must understood of prayers and readings which women say in their own groups. Then when he says, it is the same as if, he proves the above admonition. First, he induces a proof; secondly, he submits judgment of the proof to his hearers (v. 13). In regard to the first he does two things: first, he induces a proof; secondly, he excludes an objection (v. 11). In regard to the first he presents three proofs: the first is taken by a comparison to human nature; the second by a comparison to God (v. 7); the third by a comparison to angels (v. 10b). In regard to the first it should be noted that nature, which provides the other animals with aids sufficient for life, offers them to man imperfectly, so that through reason, art and use, man with his hands provides those things for himself, as it gave bulls horns for defense; whereas men prepare for themselves arms for defense by reason's direction of the hands. Hence it is that art imitates nature and produces things which nature cannot make. Thus, for the covering of the head, nature gave man hair. But because this covering is not sufficient, man through art prepares for himself another covering. The same explanation is true in regard to the natural covering and the artificial. But it is natural for a woman to have long hair. For she has a natural disposition to this, and further a definite inclination is present in women to take care of their hair. For this is true in the majority of cases that women take more pains with their hair than men. Therefore, it seems to be a condition suitable to women that they use an artificial covering for the head more than men. In regard to this he does three things: first, he mentions the suitability of a natural and artificial covering, saying: It has been stated that a woman not covering her head dishonors her head, for it is the same, namely, the same thing to be deprived of an artificial covering, as if she were bald, i.e., as if she were deprived of the natural covering of hair, which is predicted as punishment for certain people: "The Lord will smite with a scab the heads of the daughters of Zion and the Lord will lay bare their secret parts" (Is 3:17).”
