Religion: Denominations Interpretations and Conviences (Geared towards the religious)

This thread is meant to discuss with religious individuals (the non-religious are not bared from the discussion FYi) their view on their own religion. There are many different denominations of each religion, Christianity alone has over 30,000, and although some have just hair split sized differences they're enough of a difference to receive some kind of label, so they have some significance. With that in mind there comes an issue of "who's right". People who interpret certain writings in X way say people interpreting it in Y way are wrong and vice versa. Most religious text use unfalsifiable claims to justify themselves and/or disprove others and there's a lot of missing writings as well (Jehova's wife for example) so what may and may not be right may not be accurately determine with current interpretation (an example being you're asked to interpret a poem, then later being told there's at least a quarter of the poem missing so it may mean your interpretation is false). As well there's an issue of "convenience", some people just choose what to believe regardless of any proof from their religious text to back up what they say is right (ever see the mental gymnastics of a christian conservative trying to interpret the lesson of a rich man having a harder time getting into heaven then a camel going through the eye of a needle... it's worthy of an Olympic gold medal). Even the extremist have some reinforcement to their actions which is certainly a lot more then what can be said of some people.

With all that in mind I'm curious as to what, besides faith (I'm not saying it's not an answer, but it's the obvious one and I'm kind of hoping to get a "real" explanation), makes your particular religion, denomination, and/or practices seem right.
