I did a bit of reading but wasn't really finding what I was looking for. In relationship to the Trinity, why would you say Jesus is called the Son, and not another name like the brother? Is it the conception by the Spirit and woman that determined the name Son from all eternity? Is it simply the roles that determine the titles? We have the Father, Son and Spirit. But if God chose to, couldn't He have used brother, brother, and Spirit, if He wanted those terms?
