Though it may be useful to distinguish between the 'party line' of religious doctrine (the official church doctrine / dogma) and the church members particular beliefs that may or may not diverge from the party line.

The majority (though not all) of the worlds major religions have a party line whereby that religions conception of spirituality is the ONE TRUE conception of spirituality as was given to people by way of DIRECT REVELATION FROM GOD.

While individual members of a particular religion might diverge from the party line I think that it is important to note that that is indeed the main party line of the majority of the worlds major religions.

The idea that a particular religion has access to the ONE TRUE conception of spirituality directly conflicts with the idea that there are MANY EQUALLY VALID conceptions of spirituality.

Either there is one true conception (which is an intolerant view) or there are many equally valid conceptions (which is a tolerant view). Both views can't be true, however. Indeed... One way to understand the later view is as a denial of the former....
