What is this doctrine?

The doctrine of the Fatherhood of God and the Universal Brotherhood of Man when applied incorrectly is dangerous. It assumes that God is the Father of all men, therefore making us all brothers and sisters in this one creator, regardless of your personal religion or beliefs (i.e. Universal Sonship). This defies scriptures such as John1:12, John 14:6. It denies the unique role of Jesus as the ONLY savior.
