My position is not speculative, as I have presented strong scriptural evidence that supports why Simon, Joseph, James, and Judas Thaddeus, are not Jesus's brothers, as in "a male born from the same womb" (see post #261). Until you prove otherwise, as it stands, your position remains pure speculation presented as fact.
do all theologians agree on the authority of Peter the apostles and their successors? Matt 16:18 18:18 who declare in Holy apostolic council that Mary is the mother of God, perpetual Virgin, immaculate conception?
