I always assumed that when the Holy Spirit came upon Mary for the conception of Christ that it was a supernatural implantation that did not break the hymen. Then I realized that if it was not broken at conception, that meant Jesus had to break it with his head at his birth. Apart from the angels and shepherds coming to see the baby born, there is no indication in Scripture that his birth was out of the ordinary.
Years ago I read a marvelous book called,
Why the Hymen? by Sheila Cooley. In that book she explains that the breaking of the hymen was the blood covenant of a marriage. Cloths were laid under the bride on her honeymoon night to catch the blood to prove that she was a virgin. So the consummation of marriage was traditionally a blood covenant, assuming the bride was a virgin.
So the question crossed my mind while thinking about this, "If the head of the baby Jesus broke the hymen to come out, was that a blood covenant with Mary somehow?
I have no answer for this, so I am asking for everyone's thoughts on the topic. Thank you for your feedback.
Post Script.
It is apparent that people misunderstand my question. I am not asking what constitutes virginity in a woman, I asked the question if the hymen were broken by the head of Jesus did that constitute some kind of covenant with Mary?
I referred to Sheila Cooley's book, but it is clear that readers need more information. She draws upon the story of the covenant God makes with Abraham in Genesis 15:9 through :17 where Abraham cuts a heifer in half and the lamp of God passes through it. This is a blood covenant since the heifer had to be slaughtered. From this passage she draws the conclusion that blood spilled with the passing through the flesh is the covenant act. Therefore when a man marries a virgin and consummates the marriage on the honeymoon, the hymen breaks and spills blood while the act of intercourse is the passing of the flesh through the flesh.
If Mary's hymen was intact, and I believe it was since that is the medical definition of virginity, then it had to break when Jesus was born, hence my question.
