I'm sorry..."not as many sins" where, and as where? I don't quite get that part of your comment.
Mark 7:1-13. You get exactly the same teaching, to exactly the same people.
Good, I'm glad.I read Romans 3 and I must have misunderstood, as Romans 2 is clear to me.
Romans 3 is about everybody. Romans 2 is about Jewish people thinking they are better than others, simply because they had the Law of Moses. Paul's argument is essentially this: who is a worse person -- the person who doesn't know the Law, but behaves herself anyway, or the person who has the Law, and doesn't follow it? So he says that the Gentiles, who did not have the Law, are better than Jews who had it and didn't keep it.
And it makes a kind of common sense one can easily understand.
Imagine you're driving through a small village, where the speed limit is 50km/hr (or mph, if you prefer). But you get caught doing 65. The cop pulls you over.
In one scenario, you say, "Sorry, officer...I did not know the speed limit in the village was 50."
In the other, you say, "Sure I knew the speed limit was 50, officer; but who cares? I like to go 65."
Which one might be most likely to escape the ticket: the one who did not know the law, or the one who did?
In the same way, a Jew who has the Law is not, for that reason, better than a Gentile; if the doesn't obey it, she's worse. Because at least the Gentile can honestly say, "I didn't know." The Jewish person, by her own testimony as a "child of the Law," cannot excuse herself that way. She has to admit she knew what the Law required, but disobeyed it anyway.
