Every woman. Did you read 1 Corinthians 11:5? the verse before the one you mentioned?
But every woman who prays or prophesies with her head uncovered dishonors her head--it is the same as having her head shaved.
For if a woman does not cover her head, she might as well have her hair cut off; but if it is a disgrace for a woman to have her hair cut off or her head shaved, then she should cover her head.
1 Corinthians 11: 5&6
You really don't know?
OK, Here goes me, a Muslim teaching a Christian, their holy book.... again. Sheesh.
"Mary Mother of Jesus" in Google Images lol That is a massive clue to you, Oh Natural Person.
Secondly, know this, that Semites of the Middle East, always had their women observe the veil, and even today the tradition is existent - yet here you are, claiming to know what this head covering is and attempting to deny it is a veil. When clearly, anything which covers the head is a veil.
For proof, go to a Church for once and ask to speak to a "nun" - they cover their head by the way... so do our Muslim women. While the practice among Christians is confined only to the Nunnery.
Is Covering the Hair a Religious Commandment for Christian Women?
There can be only one answer to this: yes, it is! Simply open the Bible to the First Epistle to the Corinthians, chapter 11. Read verses 3-10.
But I would have you know that the head of every man is Christ and the head of the woman is the man, and the head of Christ is God. Every man praying or prophesying with his head covered, disgraces his head. But every woman praying or prophesying with her head uncovered disgraces her head, for it is the same as if she were shaven. For if a woman is not covered, let her be shaven. But if it is a disgrace for a woman to have her hair cut off or her head shaved, let her cover her head. A man indeed ought not to cover his head, because he is the image and glory of God. But woman is the glory of man. For man was not created for woman, but woman for man. This is why the woman ought to have a sign of authority over her head, because of the angels.
