Anyone have any insight into this? Perhaps there are some threads on the subject on this forum that you could point me to? (I remember seeing one recently either on this site or on another, but now I can't find it). Thanks!

Hmmm, yes there are a few threads on this subject here on the board. To find them click on "Search" on the Menu Bar. Then simply type in "New Calvinism" (including quotes). You should get 10 items in the results.
Now, as to 'insights'... There are a few here, including myself, who have serious mixed feelings about this "New Calvinism" movement. First of all, it is NOT promoting "Calvinism" in its totality, i.e., a world and life view. It has a very narrow focus on soteriology (doctrine of salvation), aka: "The Five Points of Calvinism". Consequently, the APPLICATION of all of Scripture to ALL of life is woefully lacking. For example, the Regulative Principle of Worship is ignored and in many cases violated. The first, second and third Commandments are in many instances ignored and/or violated. Then there is this matter of 'worldliness', i.e., an assimilation of media which is dishonoring to God, e.g., music, movies, theater, graphic arts, etc.
This is admittedly a 'hot' topic and one which has and will continue to divide denominations, churches and fellowship. However, I am of the opinion that this is inevitable and avoidable. What we do NOT need today is a truncated or dumbed-down Calvinism. The Reformed Faith cannot be bartered away for the sake of attracting alleged adherents. Ignoring history will produce negative and devastating results in the visible church.
