I was excited to see Episode 42: Cleon Skousen’s talk called “The Meaning of the Atonement.” One of my companions on the mission had a cassette tape of it. It’s pretty interesting. (Admittedly, it seems to be doctrinal speculation to an extent, but it’s still really cool.) He sincerely tells about some cool moments from his mission as a young man too. He’s a great speaker.
