Cyril of Alexandria
Patriarch of Alexandria, defender of Theotokos, and architect of the hypostatic union
Cyril of Alexandria was the titanic Christological theologian of the Early Church who defended Mary as Theotokos (God-bearer) against Nestorius, formulating the doctrine of the Hypostatic Union: God the Word united to Himself human flesh in one indivisible divine Person without confusion or separation.
Historical Context & Significance
Triumphing at the Council of Ephesus (431 AD) with his celebrated *Twelve Anathemas*, Cyril subsequently concluded the Formula of Reunion (433 AD) with John of Antioch, providing the theological bedrock upon which the Council of Chalcedon (451 AD) was built.
