Keener: the reason for women's head covering is to avoid distracting worshippers

Keener says Paul's concern in verses 7-9 is about distractions in worship, not headship: 'because woman was taken from man, she reflects man's image and therefore she ought to cover that image in worship lest it distract observers from attention to God's image.' Mike notes the implication: men should be uncovered so people can look at men during worship, which Keener wouldn't endorse.
