Oh there are LOADS of answers to that. One is no because the BVM stayed a BVM all her life. Another is yes because it would have been unusual, therefore documented if he hadn't...I think that James the Disciple may be someone who is cited as a possible sibling. Assuming you believe the bible, Jesus led a dangerous life so it wouldn't have been surprising if the identity of any siblings was disguised or suppressed for their safety...also and more controversially the identity of his wife ;-)
i believe not. ive never read a bit in the bible that says that Jesus hass siblings. bt Mary only had one child, JESUS, which was a gift from GOD. Because mary was n sdill is a virgin.
mmm I understand that one explanation of the virgin birth is a mix up in the greek translation..the word translated as "virgin" actually means "young woman"
Just as brothers and sisters can mean siblings, so also can they refer to a group of people bonded by a mutual affinity, e.g. monks, nuns, Freemasons &c so the Bible isn't really a help on this score.
well, maybe, mike, but if you say 'his mother's Mary and his brother's James', as per Matt 13:55, it's stretching it a bit to suppose the first name is intended to be literal and the second one metaphorical.
