From reading the document on NCT, especially the section on the Law, it seems that NCT says the Decalogue and God's moral law is obsolete and done away with. I know the wording is ambiguous and I also agree that it is possible to honestly look at the moral teachings just of Christ and those found in the Epistles and fully cover any moral obligation to holy living. You could do that. But the fact that Lutheran theologians were arguing with Puritan reformers long ago about how calls to repentance based on failure of obedience to God's moral laws were not technically part of the gospel - and the fact that a few years ago there was a move in reformed circles to do away with all these "imperatives" and disconnect attempting to follow them with sanctification; well, I can see how a Reformed Baptist preacher might be a little skeptical of NCT and especially of where it might go. This is especially true when you see that Dr. Moo's modified Lutheran theology is considered by the NCT folks as a good explanation of NCT.
I didn't mean to get off topic but what I'm trying to say is that you may not appreciate just how much the NCT folks really do want to break from any connection to the Old Testament laws. I think they mean it when they say it.
Not off topic at all, brother. I think we need to look at this more carefully (both your concerns and NCT.
Ont thing I need to point out is that these are frameworks. Just like there are different views within Covenant Theology and Dispensationalism, there are disagreement within NCT. All I can do is point out what the NCT states.
Douglas Moo and John Piper are used of examples of NCT. I agree there. But mostly in certain points (NCT leanings). Piper, for example, said he is closest to NCT but does not place himself exactly there.
My issue with your post here is there is an error in your reading.
You indicate NCT, especially the section on the Law, seems that NCT says the Decalogue and God's moral law is obsolete and done away with.
The reason you read NCT in that way is because Covenant Theology equates God's Moral law with the Old Covenant Law. But they is wrong because NCT does not.
NCT equates God's moral law with God's own nature. The link I provided explained it well. The moral commandments of the Old Covenant apply because they are universal, but the Old Covenant ended with the New Covenant.
NCT holds that the Old Covenant Law did not become void but is fulfilled in Christ. The New Covenant established the Old Covenant Law.
Another way to look at this is the Old Covenant Law foreshadowed the fuller expression of God's moral law in Christ Himself.
None of the moral commandments are obsolete. They were carried over (NOT from the Old Covenant to the Law of Christ but from the Law of Christ to the Old Covenant).
I do understand just how much a break NCT folks considers to have occurred between the Old Covenant and the New Covenant. I am a NCT folk. We do believe the Old Covenant Law was "nailed to the tree". BUT not God's moral law. That is based in the Law of Christ and merely expressed to an extent in the Old Covenant Law.
I apologize for not pointing out that distinction earlier. Your misunderstood is definitely logical as you and I look at God's moral law from different standpoints.
