In this episode of the Denison Forum Podcast, Dr. Mark Turman is joined by Dr. Jim Denison and Dr. Ryan Denison for a thoughtful conversation on the history and diversity within the Christian faith. Together, they explore the key moments that shaped the church, including the Great Schism, the Protestant Reformation, and Vatican II. They also discuss the rise of non-denominational churches and what it looks like to find a faithful church home in today’s landscape.

This conversation offers both clarity and encouragement for Christians navigating differences in doctrine and tradition—and reminds us why unity in Christ still matters.
