Realy?..Surely when you tell stories about a man that can not possibly be true you have created a fictional character? Some schmuck might indeed have lived and have been called Jesus but as soon as you attribute qualities and a heritage to this man that can not possibly be true..it's fictional
..Santa on the other hand...well that's a different story
Fictional = did not exist.

It is highly likely that the son of a carpenter from Bethlehem became a preacher and was executed after being viewed as a threat to Roman rule/Jewish religious hierarchy.
