The Person of Christ: Chalcedon and Its Critics
Two natures or one incarnate nature? How the traditions read the mystery of Christ.
Christians of every tradition confess that Jesus of Nazareth is both fully God and fully human. The hard question is not whether this is true but how it can be stated without dissolving into nonsense. If the divine Word and a human life are simply added together, the result looks like two persons sharing a name. If they are blended, the result is a third thing that is neither truly God nor truly man, and the gospel's claim that God himself entered our condition collapses. The early church spent more than a century — and four ecumenical councils — searching for language precise enough to guard the reality without explaining away the mystery.
By the end of this lesson
- Define the key terms physis (nature) and hypostasis (person) and explain why the whole controversy turns on how many of each belongs to Christ.
- State the Chalcedonian Definition (one person in two natures, without confusion, change, division, or separation) and the Miaphysite formula (one incarnate nature of God the Word) and attribute each to its tradition fairly.
- Trace the historical sequence from Ephesus (431) through Chalcedon (451) and explain why each side feared the other's preferred heresy (Nestorianism and Eutychianism).
- Distinguish a genuine difference in concept from a difference in vocabulary, using the late-twentieth-century joint declarations as a case study.
- Connect the doctrine of Christ's person to the gospel's claims about salvation and pastoral comfort.
