Gal 1:18 Then after three years I went up to Jerusalem to see Peter, and abode with him fifteen days.
Gal 1:19 But other of the apostles saw I none, save James the Lord's brother.
You'll notice that Paul did not refer to Peter as the brother of the Lord...Only James is mentioned as the Lord's brother...
Talk about illogical thinking. The mothers of the two James are explicitly named. Neither of them is Mary, mother of our Lord. Talk about foul.
Your condescension does nothing to bolster your theory...The scripture is more than clear that Jesus had brothers and sisters...
*****You’ll notice that Paul did not refer to Peter as the brother of the Lord...Only James is mentioned as the Lord’s brother...*****
James was a first cousin of the Lord. Mary, his mother, wife of Clopas, was Mary’s sister as Scripture says. There was indeed a familial relationship with James that was not true with Peter.
