Are Catholics going to hell?

Yeah that's idolatry alright. But, If you switch to another religion won't some other religion (Islam perhaps) also claim you are going to hell because you don't believe what they believe? I think god is smart enough to know whether or not you belong in heaven. Don't you think so? I wouldn't listen to other humans telling you they know gods will or what god wants, that is for you to decide. I think you know what god wants of you. Maintain faith in your personal relationship with god.
