In this episode of the Theology for the People Podcast, I sit down with returning guest Shane to explore the Council of Chalcedon (AD 451), the fourth ecumenical council of the early church.
Recorded live in Colorado during an Expositors Collective training weekend, this conversation traces the events leading up to Chalcedon, its theological breakthroughs, and its messy aftermath.
From the fallout of the Council of Ephesus, to the clash between the Alexandrian and Antiochian schools of Christology, and the mess of Ephesus II, Shane breaks down the stakes: how do we understand the two natures of Christ—human and divine—in one person?
The episode also tackles the political power plays, the deposition of bishops, and the schisms that followed, including the rise of the Oriental Orthodox churches. Plus, hear why Shane sees Chalcedon as both a triumph and a tragedy—and what it still teaches us today.
