My beloved daughter gave me her old iPod when she got a new one. I can’t work to music, so I’ve been using it only when I exercise — but that’s meant a daily lecture on the Fathers. And so far I haven’t paid a penny. I burned through the Louth lectures right away. Then, on iTunes, I found free downloads by John Cavadini, Robert Louis Wilken, Jaroslav Pelikan, John Peter Kenney, and many others. I loaded up, and I haven’t heard even half of the material I found. If you have an iTunes account, it’s really worth your while to go searching after terms like “patristics,” “Christian history,” and “Augustine.”
