Hey, grandma....we always left our kids with the grandparents.
It's heresy to suggest he married another woman after Mary, isn't it? It'd bother both Protestants and Catholics. Protestants want MARY to have other kids. Catholics WANT Joseph to be celibate after meeting Mary. (Father of the Church and all that.)
If brothers are blood brothers, then there are only two choices: They had both parents in common or they had only one parent in common.
I understand that in the Nicean/Post-Nicean era that the discussion centered around Mary being "impregnated" by 2 different "husbands" when the 1st husband was still living. They believe it made her into a "loose woman."
How would you argue against Mary being "an adulteress?"
If His mother was so unimportant, as most Protestants would have us believe, and his brothers were so numerous then why would Jesus bother to say anything and why would it be in the Scriptures?
