Are we eternal brothers and sisters with a spiritual begetting from eternal parents as taught in The Church of Jesus Christ of Latter-Day Saints? Or are we simply creatures brought into existence out of nothingness by a single genderless deity at our mortal birth as taught by mainstream Christian scholars?
According to science we could be some kind of cosmic flash of organic chemistry? Aren't we though, and isn't science eternal truth? Doesn't God exist according to eternal truth? These are some of the choices or belief systems that exist.
Christian apologists have essentially changed the terminology of family relationships to not mean what they really are to us. In other words they call Jesus the son of God as the Bible teaches but their theological seminary teaching is that Jesus is a creature of the Holy Ghost. Because Jesus and the Father are the same godly being along with the Holy Ghost they don't have a real father-son relationship. This summarily describes the doctrine of the Trinity as taught by mainstream orthodoxy.
According to these scholars we as humans are inferior creatures but can be adopted into God's family by accepting the Bible, especially the New Testament and confessing that we accept Jesus. Those that don't are condemned. This is the only way according to Bible scholars that man can be a child of God.
