01
A council shaped by theology and authority
Bishops gathered in Ephesus in 431 amid a dispute about how to speak of Christ’s person and Mary’s title. The proceedings involved theology, rival delegations, imperial authority and contested procedure; a tidy one-line summary hides that complexity.
02
Why Ephesus was an appropriate setting
The city had imperial infrastructure, a significant Christian community and a long sacred history. The Church of Mary near the harbor district is traditionally associated with the council and provides the strongest physical setting for discussing it.
03
Reading the site responsibly
Archaeology identifies the basilica’s phases and urban context, while surviving council documents preserve arguments and decisions. Visitors benefit when those forms of evidence are kept distinct and then brought into conversation.
