Mary did such a wonderful, brave and obedient thing, giving birth to the Savior, no doubt enduring gossip and talk. I don’t see why, after that, God would require her to marry some 90-year-old geezer and never have a normal marriage and more children. Having sons was so important to women in those days, too.
The only evidence that I will admit gives me pause is Jesus asking John to take care of His mother, rather than having one of His siblings do it. But I hope Joseph was way younger than 90, and I hope he and Mary were able to have a normal marriage. It doesn’t matter now, and it doesn’t affect anyone’s salvation, but I certainly think they both deserved it.
“The only evidence that I will admit gives me pause is Jesus asking John to take care of His mother, rather than having one of His siblings do it.”
That problem would still exist if the ‘brothers’ were step brothers or cousins. The nearest male kin would have been the normal choice.
“The only evidence that I will admit gives me pause is Jesus asking John to take care of His mother, rather than having one of His siblings do it.”
The Bible gives no evidence of any of His siblings believing in Him until after His death, resurrection and ascension. Given that John was the “beloved” disciple, he would be the logical choice in those circumstances.
