1 Corinthians 11:4

Every man praying or prophesying. — The reference here is to public prayer and teaching (the word “prophesying” is used in its less restricted sense). The Apostle probably does not allude to any case in Corinth where a man had actually taken part in a religious meeting with covered head. The Greek practice was for men to have their heads uncovered when joining in religious ceremonies (Grotius in loc.). To this practice St. Paul would incline, as being the national custom of the country, and as also being typical of the distinction between the sexes which he has just laid down. The Apostle’s teaching on this subject is a remarkable illustration of how completely he had overcome his old Jewish prejudice, and how the whole of his nature had become leavened with the freedom of the gospel — for it was the custom amongst the Jews for the man to pray with covered head, and the face veiled with the Tallith, as an expression of his unworthiness to speak face to face with God. It was a profound insight into human nature which enabled the Apostle to realise how an external symbol would infallibly tend to modify doctrine, and how thus the perpetuating of such a custom in the Christian Church might have hindered the full recognition of the great truth of the personal and direct communication of every individual soul with the Father.

Dishonoureth his head. — He dishonours his own head inasmuch as it is the part of his body from which Christ has taken His title as “Head of the Body,” the Church — and thus he dishonours his Spiritual Head. even Christ.
