1 Corinthians 11 v 5-6


1 Corinthians 11:5-6 
(5)  But every woman that prayeth or prophesieth with her head uncovered dishonoureth her head: for that is even all one as if she were shaven. 
(6)  For if the woman be not covered, let her also be shorn: but if it be a shame for a woman to be shorn or shaven, let her be covered. 


11:5-6. It cannot be unequivocally asserted but the preponderance of evidence points toward the public head covering of women as a universal custom in the first century in both Jewish culture ([apocryphal] 3 Maccabees 4:6; Mishnah, Ketuboth 7. 6; Babylonian Talmud, Ketuboth 72a-b) and Greco-Roman culture (Plutarch Moralia 3. 232c; 4. 267b; Apuleius The Golden Ass 11. 10). The nature of the covering varied considerably (Ovid The Art of Love 3:135-65), but it was commonly a portion of the outer garment drawn up over the head like a hood. 

It seems that the Corinthian slogan, “everything is permissible,” had been applied to meetings of the church as well, and the Corinthian women had expressed that principle by throwing off their distinguishing dress. More importantly they seem to have rejected the concept of subordination within the church (and perhaps in society) and with it any cultural symbol (e.g., a head-covering) which might have been attached to it. According to Paul, for a woman to throw off the covering was an act not of liberation but of degradation. She might as well shave her head, a sign of disgrace (Aristophanes Thesmophoriazysae 837). In doing so, she dishonors herself and her spiritual head, the man.
