Joseph has been re-reading a book by Hilaire Belloc, called The Great Heresies, and he wanted to talk both about the book and the fact that Catholics belong to a substantial tradition and ascribe to a real body of teaching, to which we can be in alignment or out of alignment. And he's glad that that exists.
