According to Osho, he is neither against God nor Jesus Christ; opposition requires an existent God. His finding, after searching within and without, is that God does not exist—so there’s nothing to oppose. He rejects both theist and atheist fanaticism and counsels the Buddha’s middle path: drop polarizing beliefs, rely on direct experience, and transcend the mind’s extremes.
He isn’t against God or Jesus; he says God isn’t there to fight about, so stop choosing sides and trust your own experience instead of extreme beliefs.
