Stephen Prothero, author of God is not One, and a professor in the Department of Religion at Boston University, offers a twelve minute audio introduction to each of the world's major religions.
The series is called World Religions 101 and was produced in 2014 with Interfaith Voices and host, Maureen Fiedler.
Prothero outlines the the central problem each religion defines and the solution it offers. For example, he notes that exile is the problem in Judaism and argues that the solution is return "through storytelling and the law."
These clips are ideal for students either as an introduction to each religion or as a review of each religion.
