With my iPod and my commute by train a couple of days a week, I've become a serious listener to podcasts.
One podcast I've really come to value is Pray-as-you-go, a ministry of the Jesuits in Britain. (Thanks to Teresa at Blog by-the-Sea for the reference.) Each Monday through Friday podcast contains some sacred music, a reading from the daily lectionary, some thoughts for meditation on the reading, and a second reading of the same lectionary passage. A sort of audio Lectio Divina. Quality stuff.
Also available via podcast is the ELCA's Grace Matters radio program, hosted by Peter Marty, son of distinguished Lutheran scholar Martin E. Marty. You've got to appreciate someone who can both interview Philip Yancey, evangelical author of What's So Amazing About Grace? and quote liberal theologian Marcus Borg. Worth listening to.
Just two examples. There's lots out there to keep your iPod busy.
