John Piper has some responsibility for in his Gaffin lecture he gives 13 points regarding something called ‘New Calvinism’ or ‘the new Calvinism’ some of which it is said to share with Old Calvinism and all of which he offers as ‘features’ and not as defining properties. That’s not a lot of help. The language-game of denominational religion. It ought to remind us of the words of Bishop Berkeley, ‘They first raise a dust, and then complain they cannot see’. Though in this case ‘and then assert they can see’. (Not so much 'Tulip' as 'Chrysanthemum'.) But there are more varieties still: 'Rabbi' Duncan reminds us of 'high' Calvinism, and by implication of a 'low' variety. And William G. T. Shedd refers to Calvinism 'pure' and 'mixed'. Oh, and hyper-Calvinism. Old, new, high, low, pure, mixed and hyper. And more, no doubt.
