Review Questions

• How did Cyril of Alexandria influence the outcome of the Council of Ephesus?
  • Cyril of Alexandria was a key figure at the Council of Ephesus, where he championed the view that Jesus was one person with two natures—divine and human. His theological writings laid out arguments against Nestorianism, which proposed a separation between these natures. Cyril's strong stance led to the council declaring Nestorius’s teachings as heretical, ultimately affirming Mary's title as Theotokos and solidifying Cyril's influence on Christological debates.

  • Cyril's opposition to Nestorianism was rooted in his belief that separating Christ’s divine and human natures undermined the core tenets of Christian faith. He argued that if Christ were divided into two distinct persons, it would affect the understanding of salvation and redemption. This led to significant doctrinal developments in affirming the unity of Christ’s nature, which became critical for later councils and theological discussions within Christianity.
