John Henry Newman's classic book, An Essay on the Development of Doctrine, shows how doctrine isn't stagnant but in fact develops over time, much like an acorn grows into a sprouting oak tree. In today's episode, we share the first half of a talk Bishop Barron gave on the book and its influence. (Pick up your Word on Fire Classics edition of Newman's Development of Doctrine, which includes an Introduction by Bishop Barron!)
