Epikoros

Okay kiddo, so you know how we have different religions and ways of thinking about the world? Well, in some religions, there are certain beliefs that are really important to follow. In Judaism, there is a word called epikoros that basically means someone who doesn't believe in those important beliefs. It's like if we were playing a game, and we all decided to follow the rules, but then one person just decided they didn't want to play by the rules anymore. They would be called an epikoros. In Judaism, being an epikoros is not a good thing because it means you're not following the beliefs that are really important. But it's okay if you have different beliefs as long as they don't go against the important ones. Does that make sense?
