What’s demeaning to women is that the virgin birth doctrine has its roots in the idea that sex is unclean, and women who have had sex are unclean.
Well I’m pregnant with number three so what does that make me lol!
The virgin birth doctrine relates to the need for Jesus to be sinless from the time of conception, otherwise His sacrifice would not have atoned for all sin. He was the perfect Lamb sacrificed for us. In Jewish thought, sin comes from the father, therefore not having a human father assured that Jesus was conceived without sin. Instead, His father was God the Father!
Talking about being "conceived without sin",another Catholic non-Scriptural dogma is that Mary herself was conceived without sin. Basically, it says that it was ok for God to become a man, live in our dirty world, go to the cross... but somehow it was not ok for him to be incarnated in the womb of a sinner. It figures!
