I don't have a formed opinion about the bible but think on this:
All the sources that have done us doubt and have diferent perspectives about the book in occident are Teosophic, that's mean, the new age, and the root is Luciferianism.
So, we haven't a straight opinion about it, all the doubts comes from luciferianism who is Terribly partial against it and All of us have a opinion influenced by that in some way.
All the sources that says the bible isn't historical and Jehoshua'ha messaiah didn't exist are Teosophists, and None of the teosophic sources are profesional, are
all Amateur. Because is Proven that the book Is historic and Jehoshua'ha messaiah exist.
Am sorry, but that's the way it is. There are dozens of writers in the early times, both christians and enemies of christianity that confirm the figure of Jehoshua.
Read "Who's playing jesus games?" a book from Jonathan Grey, there he compiles the cientific evidence about it; its just overwhelming. Versus the amateur teosophists who's sources are omitions, semitruths, inventions, and phrases out of context and that's just the way it is.
Before investigate the subjet propely and investigated the New Age and the other part, the wingmakers/urantia movement (the 2 sides of the hegelianish creation of the new world order religion) Im actually believes in that, but the evidence against those movements are just to much so I Had to change my view.
In fact, a lot of people changes into actual christianity when they investigates the creation of the new age movement, what's is behind the "ascended masters", the cases of contactism and the truth about luciferianism who are a deceive-by-desing religion, and so on.
To think about.
