I missed a lot this past week due to Hurricane Sandy. Nathan Bingham has posted free downloads to audio and video of R.C. Sproul's Luther and the Reformation. Thanks Nathan! I've probably mentioned this before, but I was more or less introduced to the importance of the Reformation through Dr. Sproul's materials many years ago now. I would assume such is the case for many folks that came out of broad Arminian evangelicalism into a confessional church.
Dr. Sproul is Reformed, but this doesn't mean my Lutheran and Roman Catholic friends wouldn't benefit from these free lectures. Even if you don't agree with Dr. Sproul on everything, learn how to sift. That is, interact with the materials by sifting the stuff out you think is helpful as opposed to the stuff you disagree with. I do this all the time with Reformation materials.
