Today we commemorate Cyril of Alexandria, Pastor and Confessor. Cyril became Archbishop of Alexandria in AD 412. A true defender of the faith and orthodoxy, Cyril produced a number of writings dealing with various theological matters. Cyril’s Christology had a significant impact on later theologians. Additionally, Cyril defended the truth that it is proper to call Mary the “Mother of God” or Theotokos, the ‘God-bearer’.
