You must explain where you get these special glasses that enable you to tell from this verse that James, Joses, Jude, and Simon were all sons of the same Mary that bore the Lord, because that verse pretty clearly says nothing of the sort.
What on Earth else could it mean?
The speaker, In addressing the issue, of what is so important or special about Jesus....
first says....he's just a carpenter ,He's Mary's son,
and he's the brother of James,Joses,Juda,& Simon and at least 2 sisters. (Thats at least six siblings.)
However I have never seen mention in the scriptures while speaking of the nativity story, that it mentions anything about Joseph and Mary trekking across the desert to the Bethlehem version of the Motel 6 looking for accomadations for the 2 of them plus six other kids. Perhaps Thats because they werent born yet? But in the Bible it does say that Jesus was Mary's firstborn son.
They are going to Bethlehem for a census , they are married, but Joseph isnt going to count "his other kids" from his supposed first marriage in the census?
In Mark 6:3 Starting with the mother they then name the rest of the family of Jesus that all of these people present can identify with.
At face value, any one without an agenda would say that the speaker just named off members of the same family.
But if you put on the special glasses, suddenly these words take on an entirely different meaning and you have a first century Brady Bunch with a widower and his sons and daughters marrying a perpetual virgin.
If we all agree that the Bible is the word of God and divinely inspired by the Holy Spirit, why would we think that we are supposed to take these words at anything other than face value?
