One of my favorite Catholic podcasts is the one put out by St. Irenaeus Ministries that concentrates on scripture and theology.
Today they had a bonus in their feed.
In this recording from the 2011 Rochester NY Chesterton Conference, Hilaire Belloc (played by Kevin O’Brien) takes a sweeping overview of Christian history with a look at what he conceptualized as the five major heresies.
There is also an introduction by Joseph Pearce in this episode and Kevin O’Brien as Belloc is simply great and this performance makes up most of this audio.
