Do you guys think it would be possible for Jesus to have had brothers and sisters? Afterall, isn't it in Mark 4 that his brothers and sisters are mentioned?

Imagine being a brother of Christ....what would it be like to live in your older brother's shadow?

Mary: "You know what James? Why can't you be more like Jesus"

Anyway....so seriously. What do you guys think about Jesus having syblings. Would the the fact that Mary wouldn't be a Virgin anymore matter?

I don't see why not? I would hope that Mary and Joseph did have children after Jesus.

Half brothers and sisters

Exactly half brothers and sisters and remember that Mary and Joseph had an angel come to them and explain ... they knew who and what Christ was (the only-begotten Son of God). They knew He was true man yet true God.
I wish to thank everyone for making this such a respectful and interesting conversation. I am enjoying it so much.

For 700 years earlier ISAIAH HAD TOLD THAT THE CHRIST WAS COMING, it was well known among the Hebrews.
Therefore the LORD HIMSELF shall give you a sign--Behold a virgin shall conceive and bear a son and shall call his name IMMANUEL

Great points you bring up Saved2.
