I don't see how a transgression can exist without some kind of law. By law I mean the Bible, because I think the bible teaches God's law (correct me if you don't agree about that otherwise we could go around in circles )
It cannot be true that the Bible is the only law. The reason being is if it were so it would cause class distinction. Those with the law (Bible) and those without it. Those understanding it and those not understanding it.
To believe it is law is also elevating Israel above mankind because without Israel there would be no Bible.
The Bible and Israel are helpers, not law. (Lawyers LOL)
