@Gator-FBC,
The only things I know of (and I'm no theologist) is the idea of converting others (ie causing apostasy, as opposed to experiencing it).
Interestingly in the Abrahamic religions the later the religion started the more forgiving it is of it's predecessors. So Christians use the history of the jews as part 1 of the bible (the old testament) and the Koran recognises christianity and judaism as 'divinely revealed' religions.
