@Waton, I wasn't suggesting for a moment that there are geniuses of religion, just that religion was not Newton's specialism, being more akin to a hobby, like his interest in alchemy. He had cracked gravity, so he gave Biblical prophecy and making gold from base metal the object of his brilliant mind as well.
It would though be interesting to consider what a genius of religion would look like!
The candidate would have to be able to pull out of thin air ideas which have no evidential basis but have an aura of the sacred about them and then by using these, manipulate the minds and hearts of his audience to financially reward him for his unsupportable promises and deceptions. TV evangelists perhaps?
We could put forward Fred Franz, not motivated by wealth but for the whole of his long lifetime he communicated his utter conviction of Biblical certainty yet proved eventually to be totally wrong. How many did he influence: say twenty million JWs over sixty years? Genius? More of a fixated, narcissistic fanatic I think.
