I have been using the Teaching Company and their Great Courses for several years now. Most of them are very good. But when it comes to the Christian Faith and the Catholic Church I dare you to find one that is truly Christian or Catholic.
Now they have a competitor: Catholic Courses. Joseph Pearce is a friend of mine and he is behind this effort. I hope good Catholic jump on board and support this orthodox endevour.
