This podcast by Dr. Michael Barber, Professor of Theology at John Paul the Great Catholic University in SanDiego, and Author at The Sacred Page, covers the Liturgical Roots of the bible, and by that I mean how the books of the bible were determined to be scripture by the early church in large part by whether or not the book could be read during Mass, or read in the liturgical worship of God.
Here is a two page bulleted synopsis of the radio show. (highly recommended for a brief of the show or to follow along with Dr. Barber as the show goes on.)
