About this episode

The episode explores the Catholic understanding of how doctrine develops, emphasizing its roots and examples.

The Acorn and the Oak: Development of Doctrine, Part 1. In this first part of our conversation with Cory, we explore the beautiful Catholic understanding of how doctrine develops. Far from “making things up” or changing with the culture, the Church deepens her grasp of the unchanging deposit of faith handed on by the apostles. Greg and Cory unpack Saint John Henry Newman’s classic idea, trace its roots to the early Church, and walk through clear, non-controversial examples like the Trinity, Christ’s two natures, sacramental theology, and the Marian dogmas. Using the acorn-to-oak image and Newman’s seven notes, they show how the faith stays the same while growing richer and more articulate over time. Perfect for Protestants wondering about “Catholic additions” and anyone wanting to understand how the Church avoids both fundamentalism and fluidity.
