For when Gentiles, who do not have the law, by nature do what the law requires, they are a law to themselves, even though they do not have the law.
Romans 2:14

Was Paul saying that Gentile converts to Christianity don't need to keep the Law of Moses because they have their own, separate law? Not quite. He was saying that even those Gentiles who have never heard of Moses will still be judged according to what they do understand of the Law, even if they don't know that's what it is.
