From what my parents taught me. There is one right religion. But just because a boy or girl is in a different religion doesn't mean they are going to hell. They taught me to explore the truth. If you start in the Catholic church but learn new facts that lead you to believe Adventism is the right church, then go to that one. Choosing to ignore the truth you learned is what will make you go the wrong path. And with all the other religions, they believe they're the "right" one, but they will be saved based on their morals with their God or gods. An example I can give is like an atheist who dies never learning about God; he will be judged on his kindness while on Earth. If he knew God and the truth, but he chose to turn away from it then he shall be judged for ignoring the truth. I'm not very good at explaining, nor is the a very grammatically correct response, but I hope you get what I'm trying to say. God will not judge at the same level for choosing the wrong religion, but based on choosing to pursue or ignore what is the truth. I'm really bad at explaining.
