I did, and it was very interesting and reasonable sounding post. Had it been to me I would have had a few comments/questions:
The problem with this interpretation [that Jesus had half-siblings] is that, according to Scripture, some of the people listed as his brothers appear to not have had the same Mother as Jesus.
And along the same lines:
Another problem with this theory [of multiple Christs with God and Mary as "parents"] is that the Mother of two of these brothers is still alive at the time of the Crucifixion, which would mean that Joseph either divorced Mary later on, was actually a divorcee at the time of his espousal to Mary, or that Joesph was married to more than one woman. Those are all problematic contingencies if we attempt to force them upon Scripture.
I am unfamiliar with these scriptures and would very much like to know what they are. Is one of them from a later statement : "Elsewhere, however, we learn that Joses and James actually had a different mother. (Mr 15:40, Mr 15:47.) If so, is it really clear that all these passages are talking about the exact same people? We've already seen how many "Marys" there are, and how many there were named James. Plus, even in Mark 15:41 it says there were many other women there.
Another interpretation is that these "brothers" were cousins of some sort or other. (First cousin, second cousin, third cousin two times removed....) It's not an unreasonable argument, in that Scripture often mentions brothers and sisters when it is in fact seems to be talking about some other relationship. There are many examples of this, ...
I agree there are examples of this, and examples of "brother" being used in purely the spiritual sense. To this day we refer to "our brothers and sisters in Christ". But especially in Mt. 13:55, et seq., that identifies Mary by name and Joseph by profession, and then lists brothers by name (and unnamed sisters), it just seems the flow of the sentence is meant to mean biological half-brothers. The people couldn't have known the truth about the Virgin birth, so it would have been normal for them to think of regular bio-brothers, since they identified in the same sentence what they thought to be both his bio-parents.
"So the soldiers did this. But standing by the cross of Jesus were his mother, and his mother's sister, Mary the wife of Clopas, and Mary Magdalene. (John 19:25)
Now, we can see that there were a lot of Marys at the foot of the Cross with Jesus when he was dying. The Scripture I would like to call your attention to, however, is "standing by the cross of Jesus were his mother, and his mother's sister, Mary...." Now, if we take this translation in an entirely literal sense, Mary has a sister named Mary. ... Perhaps a more plausible reading of this verse is to say that the language used in this Scripture did not distinguish between sister and cousin or other relative, even though our language forces us to translate in such a way as use a word that either conveys one class of relationship or the other.
My simple little interpretation of this would be that the verse speaks of four people: (1) Mary mother of Jesus, (2) her sister who is unnamed, (3) Mary the wife of Clopas, and (4) Mary Magdalene.
