Have you read Peter Masters' expose of the New Calvinism in his article, The Merger of Calvinism with Worldliness? Masters points out that leaders of the movement are good speakers but they overlook the problems of worldliness and a lack of personal consecration.
Whatever their strengths and achievements (and some of them are brilliant men by any human standard), or whatever their theoretical Calvinism, the poor stand of these preachers on these crucial issues will only encourage a fatally flawed version of Calvinism that will lead people to be increasingly wedded to the world, and to a self-seeking lifestyle. Truly proclaimed, the sovereignty of God must include consecration, reverence, sincere obedience to his will, and separation from the world. You cannot have Puritan soteriology without Puritan sanctification.
You will have to read the short article and decide for yourself. But I think you will agree that these are valid concerns. Good doctrine should never be mixed with compromise or worldliness.
