Jesus' authority as only human
This is not a common Christian belief, most churches believe in the Trinity. Adoptionism - This movement believed that Jesus was born human and was later adopted by God at Baptism
Arianism - The idea that Jesus is not divine. Jesus was created by God to fill a role and the title 'Son of God' was an honour given by God.
The Cathars - Taught that matter was too corrupt for God to become the incarnate - Jesus Christ could not be God in human form
Unitarianism - a deistic understanding of God - once creation was complete God ceased to exist - Jesus was a prophet
