Thomas Aquinas, on 1Cor 11:4

“Every man praying or prophesying with his head covered, disgraceth his head.”

“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.”
