my opinion is religions are based on interpretation. No 2 faiths in the same religion are EXACTLY the same(like snow flakes), because they are all based on personal interpretation. meaning, it is subjective, unless you have an exact clone which is highly unlikely. Each sentence in the bible or koran ect... will have a slightly different meaning to each person who reads it, even if it is a minute difference. one word can have many meanings and tones. put these words together and that further diversifies the possible interpretations of just one sentence. then, put together a whole book and you have over a billion possibilities. example: you can have 'person A', who hangs on every single word of their book and in their own eyes, they are a strict devout religious person with a strong faith. but, 'person B' can go through the exact same process and come to a different conclusion. they may perceive their own interpretation be even more strict and have a "stronger" faith. therefore, in their own eyes, 'person A' is a sinner. just look at the wide range of people who worship the koran for example. some focus on peace, some focus on hate and violence and some are everywhere in between. however, many claim that they are right and the other group is misguided. This conflict is found in all religions. (I'm not just singling out Muslims). who is to say they are holier-than-thou? my point is its all based on personal interpretation.
