God is one: Traditional Christianity says that God is one, yet insists that there are three distinct Divine persons of Father, Son and Holy Spirit. When you have three persons who are all–knowing, all–powerful, and all–present it makes three Gods. New Christianity says that God is one (Mark 12:32, Isaiah 44:6, Zechariah 14:9). The one God (out of love and concern for the human race and the state of humanity at that time) took on a physical human conceived of the Divine and born of the virgin Mary. Within the human of Jesus was the Divine itself – His soul was divine. Throughout His lifetime Jesus gradually got rid of what was merely human and took on more and more of the Divine within Him until He made His human completely Divine. This means, God is one, within whom is the Divine Trinity, and He is the Lord God the Savior Jesus Christ (Matthew 28:18). Just as we all have a soul, a body, and the actions of our life (and are one person) so it is with God. The Father, Son and Holy Spirit are names given for the soul, body, and activity of the one God. One God, one divine person.
