Explained in my post #26:
Ceremonial laws (which kept the Jews separate from the Gentiles) were abolished on the cross (Ephesians 2:15), including circumcision.
You are avoiding my question - you are not explaining how Ephesians 2:15 focuses on the ceremonial laws to the exclusion of other laws, like the 10 commandments. Yes, the "ceremonial laws" kept Jews separate from Gentiles, but
so did all the other elements of the Law of Moses, including teh 10.
The Decalogue was upheld (Romans 3:31) law
Romans 3:31 is not specific to the Decalogue - it refers to the entire Law of Moses. I agree that Romans 3:31 is a challenge for those of us who believe the Law of Moses (all of it, including the 10) is now retired. Here is my argument about Romans 3:31
Here is that famous
Romans 3:31 passage:
Do we then nullify the Law through faith? Far from it! On the contrary, we establish the Law.
On the surface, this seems like a ringing endorsement of the position that that Law, including the 10, remains in force.
But, of course, we also have this from the same letter:
But now we have been released from the Law, having died to that by which we were bound, so that we serve in newness of the Spirit and not in oldness of the letter.
Obviously, there appears to be a contradiction.
Now back to
Romans 3: Paul starts with a treatment of how both Jew and Gentile are sinners even though the Jew was entrusted with "the actual words of God". Next we get this critical transition:
But now apart from the Law the righteousness of God has been revealed,....
Paul is telling us about an unfolding story, and pointing out where we are in that story. And where are we? We are at the point where Jesus enters the story and justification by faith is made clear (as
opposed to justification by the Law).
This leads to the obvious question - was the Law a mistake?
Do we then nullify the Law through faith?
Answer: no, we "establish" the Law in the very specific sense that we affirm its fundamental goodness and proper role in the evolving redemption narrative even though the Law has fulfilled its role and can be retired.
This, I suggest, is a plausible way to understand
Romans 3:31.
