The unnaturalness of natural theology: the witness of Rodney Holder's Karl Barth

Compared to the colourful polemics of previous centuries one could be forgiven for reading much recent theology as a little anaemic and even lifeless, perhaps an eminently bourgeois game involving intellectual posturing. What such a polemical mood lacks in modesty, however (and in itself this is no insignificant loss but one characterising something amiss at both the scholarly and the theological levels), it gains in passionate commitment to a task. In other words, there is something worth arguing about, and therefore arguments and perspectives matter in some way or other. Why they matter is itself a significant question, and various ideology critics indicate that more is going on than might at first meet the eye. What is happening when Karl Barth announces a plague on the houses of the natural theologians, and accuses the analogia entis of being 'the invention of the anti-Christ'?
