What? I don't see the threat to Mary's life or limb that is apparently visible to others. If the other brothers did not believe in Jesus as Messiah, so what? Would they have locked Mary in a cage and forbid her to believe what she wanted? Would that have changed her beliefs or role?
Wasn't it better for her to be with believers ?
Presumably. If such actual unbelieving blood children of Mary actually existed, which of course is our point that they did not.
