1 Corinthians 11:10
7 For a man should not have his head covered, since he is the image and glory of God. But the woman is the glory of the man. 8 For man did not come from woman, but woman from man. 9 Neither was man created for the sake of woman, but woman for man. 10 For this reason a woman should have a symbol of authority on her head, because of the angels. 11 In any case, in the Lord woman is not independent of man, nor is man independent of woman. 12 For just as woman came from man, so man comes through woman. But all things come from God.
Philo On Dreams 1.232
(1.231) And a proof of this may be found in the oracular answer given by God to the person who asked what name he had, "I am that I Am," that the questioner might know the existence of those things which it was not possible for man to conceive not being connected with God. (1.232) Accordingly, to the incorporeal souls which are occupied in his service, it is natural for him to appear as he is, conversing with them as a friend with his friends; but to those souls which are still in the body he must appear in the resemblance of the angels, though without changing his nature (for he is unchangeable), but merely implanting in those who behold him an idea of his having another form, so that they fancy that it is his image, not an imitation of him, but the very archetypal appearance itself. (1.233) There is then an old story much celebrated, that the Divinity, assuming the resemblance of men of different countries, goes round the different cities of men, searching out the deeds of iniquity and lawlessness; and perhaps, though the fable is not true, it is a suitable and profitable one.
Notes and References
"... Paul also gives another rationale for his admonition to the women - 'because of the angels.' Since the subtexts of this passage are the creation stories, the mysterious angels of verse 10 should probably be understood in connection with these stories. Paul's reference to angels may be to the cherubim who guarded Adam and Eve from approaching the tree of life (Genesis 3:24). Since the angels' former role of separating men and women from the tree of life (Genesis 3:24) is abrogated in this time when the end of the ages has come (1 Corinthians 10:11), they are now present at worship? Whether or not Paul considered that precisely the same angels who used to guard the tree of life were present at the worship, in light of the Jewish-Hellenistic orientation of his readers, Paul's appeal to the angels is a reminder of God as creator (Cher. 27-28) and of God's beneficent and revelatory presence with the worshipers? Philo considers that God cannot communicate directly as "friend with friends" with souls who are still in the body and so God gives "Himself the likeness of angels" (Somnium 1.232). Paul affirms that angels are present with women who are experiencing their salvation in gifted intimacy with God through prayer and prophecy ..."
