1 Corinthians 11:15

But if a woman have long hair it is a glory to her. To let the hair grow long is contrary to what becomes man, is the mark of a weak and effeminate mind, unless it is done because of ill-health or intense cold. Hence S. Augustine reproves some monks who wore their hair down to their shoulders, to gain the appearance and reputation of holiness (de 0p. Monach.). Again, it seems fitting for a man to pray with uncovered head, for a woman with covered, as the Apostle has proved here. The woman ought, therefore, to let her hair grow long, but not the man, for her hair was given her for her covering.

Take note, however, that it is not absolutely enjoined, either by natural, Divine, or ecclesiastical law, that a woman should let her hair grow long and man should not. Hence, as was said in the notes to ver. 6, religious women cut off their hair. On the other hand, the men of some tribes, like the Gauls, used to let their hair grow long for an ornament. Hence we get the name of Gallia Comata. Homer, too, frequently speaks of the "long-haired Achæans." The Romans, also, in ancient times, grew their hair long, and did not apply the scissors till the time of Scipio Africanus. Pliny says (lib. vii. c. 59) that the first barbers came into Italy from Sicily, A.U.C. 454. Lycurgus also enacted that the Lacedæmonians should retain their hair. S. Paul, therefore, is not laying down any rule, but merely points to the teaching of nature, that it is fitting for a woman, when she goes out in public, to go with bonnet and veil, but not for a man. Still, he here adopts the decency taught by nature, and wishes the Corinthians to observe it as if it were a precept, hence he adds
