There is a good question lurking behind the confused, and wrong phrasing: the issue is to acquire a universal public philosophy that is intelligent about religion, but also secular.
Such a thing was born in the phase of the Enlightenment, of course, and even more to the point, in the phase of German Classical philosophy, whose great phase was, unfortunately, concluded with a second-rate Feuerbachian ending, which has produced a mainstream. The ‘new atheism’ is one such mongrel descendant.
The phrasing of this article’s title shows the problem: the provincial character of ‘Christian’ culture, and the need to pass beyond that. But the results can be worse, as we can see.
It seems like an easy task, but all parties most sadly are fumbling the ball, and the downhill cultural slide in all directions is sad to watch.
