Oster's religious context fully explains both male and female head covering issues in Corinth

Oster's insight explains: (1) why some men in Corinth were covering heads in worship (Roman pagan practice), (2) why Paul opposes this for men (preserve gender meaning over Roman ritual), (3) why some women were uncovering (rich women's trend). The hair-up view cannot stand because the historical background of men using cloth coverings in worship makes it impossible that Paul is talking about cloth for men but hair for women when using the same terms. Oster's work has been very well received across scholarship, even by Roman historians.
