Did you know that in Roman Catholicism, they say that Mary ascended to heaven a virgin?
How come? When the Lord Jesus Christ had other brothers and sisters? One reading of the gospel of Matthew should show you that:
53 ¶ And it came to pass, that when Jesus had finished these parables, he departed thence.
54 And when he was come into his own country, he taught them in their synagogue, insomuch that they were astonished, and said, Whence hath this man this wisdom, and these mighty works?
55 Is not this the carpenter’s son? is not his mother called Mary? and his brethren, James, and Joses, and Simon, and Judas?
56 And his sisters, are they not all with us? Whence then hath this man all these things?
But what amazes me is that people blindly believe whatever crap comes out of there without even reading the scriptures for themselves.
