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!) NOTE: Do you like this podcast?
