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.

In Episode 3 of the series Mary in the Dock: Ordinary or Extraordinary?, host Greg Smith puts the Catholic doctrine of Mary as the New Eve on trial. Protestants often object that it’s typology overreach with no explicit New Testament warrant, risks elevating Mary at Christ’s expense, and developed too late under possible pagan influence. Greg gives the strongest objections a full, fair hearing, then delivers a robust Catholic defense rooted in Genesis 3:15 (the protoevangelium of total enmity between the woman and the serpent), the Annunciation in Luke 1 (Mary’s fiat of obedience undoing Eve’s disobedience), and the clear teaching of the early Church Fathers like Justin Martyr and Irenaeus writing already in the second century. Far from competing with Christ, the New Eve doctrine is thoroughly Christocentric—it magnifies the redemption won by the New Adam and sets the stage for every other Marian teaching. Listeners serve as the jury in this conversational courtroom discussion that asks the key question: is Mary simply an ordinary woman God used for a moment, or the extraordinary New Eve the Church has proclaimed since the apostolic age? Perfect for curious non-Catholics, Protestant pastors investigating Catholicism, and cradle Catholics deepening their faith.

In Episode 2 of the series Mary in the Dock: Ordinary or Extraordinary?, host Greg Smith puts the Catholic doctrine of Mary as Mother of God (Theotokos) on trial. Many modern evangelicals recoil at the title, calling it blasphemous or idolatrous and unknowingly echoing the ancient Nestorian heresy that split Christ in two. Greg gives the strongest Protestant objections a full, fair hearing — the lack of an explicit Bible verse, the risk of deifying Mary, and the historical cautions from Calvin — then delivers a robust Catholic defense rooted in Luke 1:43 (“mother of my Lord”), the Council of Ephesus (431 AD), and the affirmations of classical Reformers like Luther (“she is rightly called… the Mother of God”), Zwingli, and the Anglican Articles. Far from Marian excess, the doctrine safeguards the full reality of the Incarnation and the infinite value of Christ’s atonement. Listeners serve as the jury in this conversational yet intellectually sharp courtroom discussion that asks the key question: is Mary simply an ordinary woman God used for a moment, or the extraordinary God-bearer the Church has proclaimed for two thousand years? Perfect for curious non-Catholics, Protestant pastors investigating Catholicism, and cradle Catholics deepening their faith.
