In 45 mins Brant Pitre gets to the heart of the Faith & Works question. Step by step, he respectfully contrasts the Catholic's and Protestant approach to this question. He also does it in a way, which you can see what trying to live and grow as a Catholic Christian actually means.
I also purchased the (2 x 1hr audio files) "What Must I do to be Saved" mp3. This first hour focuses on interesting current developments, in Protestant thinking in this field. The 2nd hour really drills down on the Catholic approach. As a layman, first listening to "Faith & Works" meant I could get the most out of the more detailed "What Must I do...", especially the 2nd part about the Catholic approach.
I would highly recommend both of these presentations. As is typical with Brant Pitre, each time I listen (& re-listen) to his lectures, there are numerous a-ha moments, when difficult and subtle arguments, just start making sense. Thank you
