I really don't think he has ever read the bible completely.. anyone who has delved into Christian teachings at all.. would not say that Jesus ... King of the Jews.. was only a derogatory sign posted on the cross.
it really shows a complete lack of familiarity with the Jesus story altogether. I mean really, christian 5 year olds know better, Jesus born king of the jews is the basis of so many Christian movies and kiddie Jesus cartoons.. if he could miss that it really shows a complete aversion to christian teaching because.. it's impossible to miss that...
and the fact that he EVEN attempts to say that Jesus came to teach and preach to the romans.. well.. I have no idea where he has been studying but it isn't in a christian church and it isn't the bible I have been reading.
theres a lot of it around i mentioned above.. people who desire, more than anything, salvation (whatever they imagine that is), but refuse to give up the rich man's goods... so they invent their own salvation and their own Jesus... there's a lot of it around.
