I don't care what any confession says because if I want that I would be RC or EO. I find this article and few others about Law in the Bible and up to now I haven t found any proper response. It seems to me that division of the Law comes from tradition and not by the clear study of the scripture. BTW there are a lot of church fathers that don't support that division.
I could respond and very easily show to you that 10 commandments were not known before Sinai and that that Law was given only to Israel. In NT Jesus improve that Law and we have now Christ law!
I put this article because I was looking for proper answer on this claims. I really don t know what to think about this article but as time pass and I don't find any proper response I am tending to think that maybe writer of that article is right.
I hope that this is clear!
