The Council of Ephesus, the third ecumenical council, begins, dealing with Nestorianism.
In 431 AD, the Council of Ephesus convenes to resolve the Nestorian controversy and define Christological doctrine.
On June 22, 431 AD, bishops from across the Christian world assembled in Ephesus for the third ecumenical council.
The primary debate centered on Nestorianism and the relationship between Christ's divine and human natures.
Led by Cyril of Alexandria, the council condemned Nestorius and affirmed Mary as 'God-bearer'.
The rulings shaped orthodox Christian theology and led to enduring schisms within the church.
Its legacy endures in ongoing Christological discussions and the authority of ecumenical councils.
