Only once you officially and honestly believe in the religion do you start to abide by things such as the hatred of gays, the disagreement with cloning and euthanasia.
Nearly every single religion to this day has been translated and re-translated and over time has lost and gained new meanings. So the original religion may be completely gone and replaced with a new one. Maybe thats why there are so many contradictions.
Christianity contradicts itself in many places for example, in Hebrew 11:6: And without faith it is impossible to please God, because anyone who comes to Him must believe that He exists and that He rewards those who earnestly seek Him. And then in Exodus 23:8 it says You shall not take a bribe, for a bribe blinds the clear-sighted and subverts the cause of the just.
In exodus 15:26 God said, If thou wilt give ear to his commandments, and keep all his statutes, I will put none of these diseases upon thee, which I have brought upon the Egyptians.
So he's pretty much saying that if u dont believe in him, your either going to go to hell or get a terrible disease. But if you do believe in him he will reward you.
A Religion is, a specific fundamental set of beliefs and practices generally agreed upon by a number of persons or sects, this is a brilliant idea; if everyone followed it the world would be at peace, much similar to communism. It works only in theory.
For example, Christianity's original basis, the Ten Commandments do not steal, do not commit adultery, do not murder, do not have any other gods ETC is very similar to the Jewsdo not steal... Do not commit adultery, dont murder, and dont have any other gods yeah similar Now...
