Why is it so important to Catholics to think that Mary was always a virgin, that she never had sex with Joseph and that Jesus didn’t have any brothers or sisters?
Is there something wrong with the sexual relationship between a husband and wife?
No, not at all! It's a wonderful thing, given us by God! But the womb where Jesus was concieved by the Power of the Holy Spirit, was a place meant for Jesus alone.
God bless you, Metmom, and thank you for asking.
