1Cor 11:4

“Others, again (the Montanists), that they may set at nought the gift of the Spirit, which in the latter times has been, by the good pleasure of the Father, poured out upon the human race, do not admit that aspect [of the evangelical dispensation] presented by John's Gospel, in which the Lord promised that He would send the Paraclete; but set aside at once both the Gospel and the prophetic Spirit. Wretched men indeed! who wish to be pseudo-prophets, forsooth, but who set aside the gift of prophecy from the Church; acting like those (the Encratitae) who, on account of such as come in hypocrisy, hold themselves aloof from the communion of the brethren. We must conclude, moreover, that these men (the Montanists) can not admit the Apostle Paul either. For, in his Epistle to the Corinthians, he speaks expressly of prophetical gifts, and recognises men and women prophesying in the Church. Sinning, therefore, in all these particulars, against the Spirit of God, they fall into the irremissible sin.”

“What is "every woman, but woman of every age, of every rank, of every condition? By saying" every" he excepts nought of womanhood, just as he excepts nought of manhood either from not being covered; for just so he says, "Every man." As, then, in the masculine sex, under the name of" man" even the" youth" is forbidden to be veiled; so, too, in the feminine, under the name of "woman," even the "virgin" is bidden to be veiled. Equally in each sex let the younger age follow the discipline of the elder; or else let the male "virgins," too, be veiled, if the female virgins withal are not veiled, because they are not mentioned by name. Let "man" and "youth" be different, if "woman" and "virgin" are different. For indeed it is "on account of the angels" that he saith women must be veiled, because on account of "the daughters of men" angels revolted from God.”

“Thus much in answer to the heretics: but we must also orderly go over the whole passage. For perhaps some one might here have doubt also, questioning with himself, what sort of a crime it was for the woman to be uncovered, or the man covered? What sort of crime it is, learn now from hence. Symbols many and diverse have been given both to man and woman; to him of rule, to her of subjection: and among them this also, that she should be covered, while he hath his head bare. If now these be symbols, you see that both err when they disturb the proper order, and transgress the disposition of God, and their own proper limits, both the man falling into the woman's inferiority, and the woman rising up against the man by her outward habiliments. For if exchange of garments be not lawful, so that neither she should be clad with a cloak, nor he with a mantle or a veil: ("for the woman," saith He, "shall not wear that which pertaineth to a man, neither shall a man put on a woman's garments:") much more is it unseemly for these things to be interchanged. For the former indeed were ordained by men, even although God afterwards ratified them: but this by nature, I mean the being covered or uncovered. But when I say Nature, I mean God. For He it is Who created Nature. When therefore thou overturnest these boundaries, see how great injuries ensue. And tell me not this, that the error is but small. For first, it is great even of itself: being as it is disobedience. Next, though it were small, it became great because of the greatness of the things whereof it is a sign. However, that it is a great matter, is evident from its ministering so effectually to good order among mankind, the governor and the governed being regularly kept in their several places by it. So that he who transgresseth disturbs all things, and betrays the gifts of God, and casts to the ground the honor bestowed on him from above; not however the man only, but also the woman. For to her also it is the greatest of honors to preserve her own rank; as indeed of disgraces, the behavior of a rebel. Wherefore he laid it down concerning both, thus saying, "Every man praying or prophesying having his head covered, dishonoreth his head. But every woman praying or prophesying with her head unveiled. dishonoreth her head." For there were, as I said, both men who prophesied and women who had this gift at that time, as the daughters of Philip, as others before them and after them: concerning whom also the prophet spake of old: "your sons shall prophesy, and your daughters shall see visions." Well then: the man he compelleth not to be always uncovered, but only when he prays. "For every man," saith he, "praying or prophesying, having his head covered, dishonoreth his head." But the woman he commands to be at all times covered. Wherefore also having said, "Every woman that prayeth or prophesieth with her head unveiled, dishonoreth her head," he stayed not at this point only, but also proceeded to say, "for it is one and the same thing as if she were shaven." But if to be shaven is always dishonorable, it is plain too that being uncovered is always a reproach. And not even with this only was he content, but added again, saying, "The woman ought to have a sign of authority on her head, because of the angels." He signifies that not at the time of prayer only but also continually, she ought to be covered. But with regard to the man, it is no longer about covering but about wearing long hair, that he so forms his discourse. To be covered he then only forbids, when a man is praying; but the wearing long hair he discourages at all times. Wherefore, as touching the woman, he said, "But if she be not veiled, let her also be shorn;" so likewise touching the man, "If he have long hair, it is a dishonor unto him." He said not, "if he be covered" but, "if he have long hair." Wherefore also he said at the beginning, "Every man praying or prophesying, having any thing on his head, dishonoreth his head." He said not, "covered," but "having any thing on his head;" signifying that even though he pray with the head bare, yet if he have long hair, he is like to one covered. "For the hair," saith he, "is given for a covering."”

“He forbids the man to have a covered head not always, but only during prayer and prophecy. He also did not simply say: with a covered head, but: having upon the head (κατά κεφαλής ἔχων), in order to abolish the covering of the head not only with clothing, but also with hair. For he who has grown out his hair also has upon his head, namely, this hair. Why then does he dishonor his head? Because he has been appointed as ruler and authority, yet he makes himself a subordinate. For the covering of the head signifies the imposition of authority upon the head; the veil on the head takes the place of a ruler and serves as a sign of subjection. Or thus: he disgraces his head — Christ — by degrading himself and losing his freedom. For just as a puny body disgraces the head, so too he who was created by God as free and self-governing, yet degrades himself as a subordinate, disgraces Christ, who is his head, as of a body. It is worthy of investigation why the apostle presents this as a sin. To the man and the woman, to one as a sign of authority and to the other of subjection, much else has been given, and among other things, that the one should have an uncovered head and the other a covered one. How then is it not a sin to transgress the boundaries of nature, for the man to adorn himself with hair and for the woman not to cover herself? He uproots this practice as a sign of willfulness, which is exceedingly destructive in church affairs. For heresies too come from this — from the fact that each person oversteps the boundaries of what has been established.”

“Having set forth the doctrine, he adds the admonition, the reason for which is taken from the doctrine mentioned. In regard to this he does two things: first, he gives the admonition on the man's part; secondly, on the woman's (v. 5). First, therefore, he says: It has been stated that the head of the woman is the man, but any man praying or prophesying with his head covered dishonors his head. In regard to this it should be noted that any man assisting a judge should display a condition or dignity, and especially assisting God, Who is judge of all. Therefore, those who assist God should conduct themselves in the best behaved and suitable way, as it says in Ec (5:1): "Guard your steps, when you go to the house of God." Now man assists God in two ways: in one way by relating human things to God, and that is done by praying: "He will make supplication before the Most High; he will open his mouth in prayer, and make supplication for his sins" (Sir 39:5); in another way by bringing things down from God to men, and that is done by prophesying, according to Jl (2:28): "I will pour out my spirit on all flesh, and your sons and your daughters shall prophesy." Hence the Apostle is careful to say, man praying or prophesying. For in these two ways man assists God as Judge, or he assists the Lord. He is said to prophesy in two ways: in one way, inasmuch as man announces to others what has been divinely revealed to him, as it says in Lk (1:67): "And his father Zechariah was filled with the Holy Spirit and prophesied, saying: 'Blessed be the Lord, the God of Israel...'" A man prophesies in another way, inasmuch as he utters things which have been revealed to others; hence, those who read the prophecies or other sacred scriptures are said to be prophesying. It is taken in this sense below (14:4): "He who prophesies edifies the Church"; it is also taken in that sense here. But it pertains to man's dignity (as will be clear below) not to wear a covering on his head; consequently, he says that every man praying or prophesying with his head covered disgraces his head, i.e., does something unbecoming a man. For as in a body, beauty depends on due proportion of the members, on proper light and color, so in human acts beauty depends on due proportion of words or deeds, in which the light of reason shines forth. Hence in an opposite way ugliness is present when something is done against reason and due proportion is not observed in words and deeds. Hence it was said above (7:36): "If someone regards himself as base in regard to his virgin, because she is over age." The following objection is raised: For many with heads covered pray in church without any disgrace, as they wish to pray more secretly. The answer is that prayer is twofold: one is private and is offered to God in one's own person; the other is public and is offered to God in the person of the entire Church, as is clear from the prayers said in the church by priests. It is these latter prayers that the Apostle has in mind here. There is also an objection against a Gloss which states that prophesying is called unlocking the Scriptures. According to this, anyone who preaches prophesies. But bishops preach with their head covered with a miter. The answer is that one who preaches or teaches in the schools speaks from his own person. Hence even the Apostle (Rom 2:16) calls the gospel his own, namely, on account of the energy he used in preaching it. But one who recites Sacred Scripture in the church, for example, by reading a lesson or an epistle or a gospel, speaks from the person of the whole church. This is the kind of prophesying that the Apostle understands here. Then there is an objection about those who chant psalms in choir with their head covered. The answer is that psalms are not chanted as by one singly presenting himself to God, but as by the whole multitude.”
