1 Corinthians 11:6

"But if a woman is not veiled, let her also be shorn: but if it be a shame for a woman to be shorn or shaven, let her be veiled." Thus, in the beginning he simply requires that the head be not bare: but as he proceeds he intimates both the continuance of the rule, saying, "for it is one and the same thing as if she were shaven," and the keeping of it with all care and diligence. For he said not merely covered, but "covered over," meaning that she be carefully wrapped up on every side. And by reducing it to an absurdity, he appeals to their shame, saying by way of severe reprimand, "but if she be not covered, let her also be shorn." As if he had said, "If thou cast away the covering appointed by the law of God, cast away likewise that appointed by nature." But if any say, "Nay, how can this be a shame to the woman, if she mount up to the glory of the man?" we might make this answer; "She doth not mount up, but rather falls from her own proper honor." Since not to abide within our own limits and the laws ordained of God, but to go beyond, is not an addition but a diminution. For as he that desireth other men's goods and seizeth what is not his own, hath not gained any thing more, but is diminished, having lost even that which he had, (which kind of thing also happened in paradise:) so likewise the woman acquireth not the man's dignity, but loseth even the woman's decency which she had. And not from hence only is her shame and reproach, but also on account of her covetousness. Having taken then what was confessedly shameful, and having said, "but if it be a shame for a woman to be shorn or shaven," he states in what follows his own conclusion, saying, "let her be covered." And he said not, "let her have long hair," but, "let her be covered," ordaining both these to be one, and establishing them both ways, from what was customary and from their contraries: in that he both affirms the covering and the hair to be one, and also that she again who is shaven is the same with her whose head is bare. "For it is one and the same thing," saith he, "as if she were shaven." But if any say, "And how is it one, if this woman have the covering of nature, but the other who is shaven have not even this?" we answer, that as far as her will goes, she threw that off likewise by having the head bare. And if it be not bare of tresses, that is nature's doing, not her own. So that as she who is shaven hath her head bare, so this woman in like manner. For this cause He left it to nature to provide her with a covering, that even of it she might learn this lesson and veil herself.
