Originally, Jesus was considered to be a man, who is the son of God. However centuries later a council decreed the idea of the trinity saying Jesus was God- or at least God in human form.....which makes no sense, since Jesus prays to God; why would God pray to himself?
If you look at the Jesus myth you see it has elements to other sun deities throughout ancient pagan countries. The death and resurection is symbolic of the sun going down and rising each day. Also of the suns apparent demise in winter (or at least weakening) and return to strength in the summer.
There is also the more symbolic attribution pertinent to the male reproductive force, but this forum is not a suitable outlet for that information.
Either way, in my opinion, to deny the existence of the deity Jesus i.e. another name for a sun deity, is just the same as denying the existence of Apollo, Ra, or the myths of Osiris and Horus.
Depending on your personal beliefs, I would argue they are all different perceived expressions of the same force; all with their own different mythologies attached to them.
