I agree. I think the problem with noting that the Law was a re-publication of the CoW is not that it cannot be understood in a proper sense but it can also lead to an improper understanding of the larger purpose of adding the Law. In Galatians 3, Paul asks an important question that I believe goes to the heart of the matter: If the Law is, indeed, a strict re-publication of the CoW then it would have to be said to be contrary to the promises of God. Paul notes that the Law is added within the structure of a CoG, given to those who were heirs to the promise and not to all men. This is bound to sound pejorative and I don't mean to be so but I think there is a sense in which it is the very error that Paul is railing against to view the Law as a "Do this and live", which is what the CoW is. That is to say that it is the Judaizers who have apprehended Moses as essentially saying "Do This and Live" when, in fact, Paul labors the point that if Moses was delivering this then he would be against the Abrahamic Promise and God Himself would have broken a Promise to Abraham. Thus, calling the Law a republication of the CoW goes too far. From a pedagogical standpoint, it communicates the wrong thing. Now, I realize that there is some subtlety here and that men need to be taken for what they're really communicating and not merely what the "headline" says. As far as it goes, I understand what some are saying by it and don't have a huge problem with it. But, as headlines go, the average man in the pew might miss the wider purpose of the Law if he merely views the Law as being contrary to the Promise when, in fact, Paul clearly states it is not contrary to the Promise but was given to fulfill the Promise. I obviously have respect for some Reformers in the past that used this language (though certainly not all did) but I think we can all agree how we've seen language mis-used in recent years and I really think it is not trivial where some have taken the republication of the CoW concept as something we ought to be concerned to qualify every time we use the term. My own view of this is that the Law was added for a gracious, pedagogical purpose where, even in the giving of the Law, the Gospel is telescoped. Certainly there were those that tried to interpret the Law as another CoW (i.e. the Pharisees) but we need to let God decide what the real purpose is and how the regenerate were to view the Law as preparing us longingly for the Messiah. It is the Gospel that the generation in the wilderness were said to reject. Finally, haven't we all seen those that take the explicit Gospel of the New Testament and turn it into a "republication of the CoW"? From the Be-Attitutdes to the Purpose Driven Life, the message of grace will always be twisted into a "Do This and Live". It's not the Law that kills but the sinful heart when it comes into contact with it (Romans 7:13-14). The CoG is ever twisted by the fallen soul unless God is gracious to grant life by it.
