The context of the NT proves it.
What I posted disproves the catholic position. No two ways about it.
Joseph and Mary had sexual relations and had other children.
I'm not sure why that upsets catholics so much.
The angel told her, "Don't be afraid, Mary. You have found favor[a] with God.The angel told Mary that she would become pregnant. Why would Mary object, since she was engaged to be married? And what would being a virgin have to do with anything?
31 You will become pregnant, give birth to a son,
and name him Jesus.
32 He will be a great man
and will be called the Son of the Most High.
The Lord God will give him
the throne of his ancestor David.
33 Your son will be king of Jacob’s people forever,
and his kingdom will never end.â€
34 Mary asked the angel, "How can this be? I'm a virgin."
Look through the writings of the early Christians. This has always been interpreted as contradicting her vow of perpetual virginity. Even Luther believed that Mary was ever-virgin.
The angel also told Joseph to not be afraid to take Mary as his wife.
It would be a strange command indeed if she was really betrothed to the Holy Spirit and considered to be e spouse of the Holy Spirit.
Also to not fear to take her as his wife includes the implicite understanding of all that entailed.
Nowhere do we see Joseph being commanded or reminded to keep her a virgin after the birth of Jesus.
Additionally, Jesus is called the son of the carpenter by the people who knew Him.
I’m sure that when Mary turned up pregnant before the actual marriage ceremony, it caused quite the scandal. I can just imagine people’s reactions when she told them she was pregnant by the Holy Spirit. Sure she was. sure her child would be the Messiah. Great excuse Mary.... It happens all the time. Joseph didn’t believe her until the angel appeared to him in a dream and confirmed what she said. I doubt many other people did either.
