If I wrote a novel about a real person and portrayed that person as a pedophile (which he was not), and covered my slander up under the guise of my story was just fiction, would that be OK?
Is the subject an historical person, or a presently extant person?
In the latter case, there may be a viable claim for libel, although the notoriety of the subject may negate the claim. In the former case, not a chance. (Although I will note that pedophilia, as wonderfully inflammatory as it is, has anything to do with the book under discussion.)
I know, I know. Jesus is a presently extant real person, as you and I both believe, but in the eyes of the law, that is a religious inclination that cannot be imposed on others or enforced by means of sanction. Properly so, in my view.
obfuscation: to make something obscure or unclear, especially by making it unnecessarily complicated - or - about as convoluted as any post here
