When I found out that BBC (my church) had listed themselves on Podcast Alley, I started looking around in their "Religion/Inspiration" section. It's a whole mishmash of Catholic, Protestant, unchurched, Jewish, music, sermons, readings... there's a little bit of everything there. I picked a few of the music feeds, but didn't find much else that I liked. I already hear the BBC sermons each week, so I wanted to find a different broadcast of Bible teaching. Too many of the feeds available are "Christian" teaching that barely mentions the Bible.. or it goes the other route, and simply reads from the Bible with no interpretation or teaching.
After searching for a while, I found something called "The Bible Broadcast". I can't recommend it highly enough if you're looking for Bible teaching like I was. "Preacher Tony" preaches "the Bible, the whole Bible, and nothing but the Bible" - using other Biblical passages to help his listeners understand whatever passage he's teaching on. His southern accent sounds hokey to me, but his message is worthwhile.
