Peter Kreeft is an intelligent and engaging writer, and he points out some important truths. At the core of all religions are the common moral truths implanted in the human heart-and, despite the political incorrectness of saying so these days, we should insist on the fact that this does actually offer a common ground among the religions. (I would go further, and say that these common truths exist also in the hearts of those who call themselves atheists or agnostics, but that’s a discussion for another day.) I recommend Kreeft, and especially his fascinating dialogue Between Heaven and Hell.
