If you are looking for an intriguing way to put an hour of your audial energies to good service, may I suggest a podcast from the CBC program “Ideas”–an interview with Catharine Pickstock and John Milbank. It serves as an excellent introduction to Radical Orthodoxy (and brings some of its more abrasive aspects to the surface). The interview is a few years old, but I didn’t find it till last week, perhaps you haven’t found it either.

Thanks for the link – have found it a very useful introduction!! (And it is good to actually hear people whose work you know SPEAK – makes them a lot more human…:-)
