Every man praying or prophesying, having his head covered, dishonoureth his head.
Praying - in public (1 Corinthians 11:17).
Prophesying - preaching in the Spirit (1 Corinthians 12:10).
Having - i:e., if he were to have-a supposed case, to illustrate the impropriety in the woman's case. The Greek custom was for men in worship to be uncovered; the Jews wore the Tallith, or veil, to show reverence and their sense of unworthiness in God's presence (Isaiah 6:2), excepting where (as in Corinth) the Greek custom prevailed. But this passage shows wearing the Tallith was introduced after apostolic times. The pagan covered themselves in sacrificing, not to be distracted by outward objects.
Dishonoureth his head - not "Christ" (1 Corinthians 11:3); but as "head" means before in this verse, He dlshonours his head (the principal member), he divests himself of his divinely-appointed dignity by wearing a covering-a mark of subjection, making him look downward instead of upwards to his spiritual Head, Christ. Why, then, ought not man to wear the covering in token of his subjection to Christ, as the woman wears it in token of her subjection to man? Because Christ is not seen, the man is, and visibly represents God (cf. 1 Corinthians 11:7).
