The more I read on this site, the more I see that ALL religions think their version of what is right and wrong is what matters. Some punish you now for disobedience to the church's rules and others supposedly give you your reward in the hereafter.
Some live their lives with more strictness. Others are more liberal.
Look at the Jewish faith. You've got from ultra Orthodox to extreme liberal. And the extremists say ONLY THEIR way is acceptable. Other factions aren't so particular. They are very much like Catholics, in reality.
