On my last vacation (back in February) I listen to the first ten episodes of a Church History Series by Fr. Michael Witt Assoc. Professor of Church History at Kenrick-Glennon Seminary in St. Louis. The whole series has over 40 hours of listening where he systematically goes through Church History in a very conversational manner. The talks are entertaining and memorable and given by a priest who clearly loves the Church. They can found here:
To get to the talks click on the upper left square. The talks are then listed on the left hand side of the screen and if you click on the talk you are given the the notes and the audio begins. You can right click on the sound horn and select the option “Save Link as” to download the talk to your computer. The talks are in mp3 format.
