Your response says NOTHING.
Rather, your response in 172 ignores the very verses. You never address them at all. Do you deny that the Bible refers to the brothers of Christ?
Because you have been given one interpretation from an institution of man, and told that it is the only acceptable interpretation, you will accept it. That’s fine; that’s your faith. But the Gospels clearly refer to the brothers and sisters of Christ. Only in ignorance or deceit can someone state unequivocally that the Gospels do not at least suggest Christ may have had siblings.
