Sorry, but your concept of the purpose of theology is strange.  Theology is about how the human community thinks about God.  There is more than just one or two schools of  theology acceptable in the church, and theology has moved on since Thomas Aquinas. 

What are acceptable titles for God in one culture, are not in another.  It does NOT reflect God's love and salvation to people enslaved to refer to God as Master and Lord.   With so many children growing up in fatherless homes, and in homes where fathers have been abusive----there needs to be other ways to think of God.
