I've been questioning this for quite some time. It all started when I had read that Jesus traces his lineage to king David not through his mother Mary, but through Joseph. But Joseph did not father Jesus.
I've also recently read an interesting article
HERE which seems to prove that king David and king Solomon were never real people and that the temple of king Solomon was mythical. The article goes into a lot of detail about Jehovah's origins, how Mount Zion isn't real and was a mystical mountain in the north pole. How Jews stole bits and pieces of other people's religious ideas to create Judaism. The article gives the etymological history of the word Zion, the name Yahwey, and even where the idea and concept of Satan came from. Are the things in that article true?
I don't know what to think or believe anymore. I'm wondering if the Cathars were right? They believed that the flesh was corrupt and that Jesus, being holy, was never a physical person, but a spiritual concept.
How can we prove to ourselves that Jesus was a historical person, of divine origin?
