Was Jesus Christ invented by the Council of Nicea?
What evidence is there that a cult existed that venerated Jesus of Nazareth as the son of God prior to the Council of Nicea? By evidence I mean in the scientific sense, not the historical sense. Copies of supposed earlier works do not count, we all know that "the victor writes the history books". References to a Jesus cult or a Christ cult do not count, there seem to have been numerous mystery cults around in the first and second centuries. I was reading of an ancient church being excavated in Nazareth that had a mosaic inscription which might be "evidence" if it can be positively dated. There should be ceremonial implements or grave inscriptions that can be dated pre-Nicea. I am not an historian so I really do not know if this evidence exists or not.
If Jesus is an invented figure it seems that we can trace the story back to Emperor Justinian and Eusibius. The Roman Empire was very sophisticated about religion by this time and certainly had the means, methods and motivation to invent a state religion. Evidence of a thriving cult that worshipped Jesus of Nazareth as Christ prior to the Council of Nicea would prove this Hypothesis incorrect.
Nothing does not exist.
