Cyril, Patriarch of Alexandria
On this day we commemorate Saint Cyril's falling asleep. On January 18 we commemorate the occasion of the Saint's restoration to his see in Alexandria after he had suffered a brief exile because of the machinations of the Nestorians. Shortly thereafter the Third Ecumenical Council was convoked in Ephesus and the blasphemous doctrine of Nestorius was condemned. See January 18 for Saint Cyril's life and works.
Apolytikion of Cyril, Abp. Of Alexandria in the Plagal of the Fourth Tone
You are a guide of Orthodoxy, a teacher of piety and modesty, a luminary of the world, the God inspired pride of monastics. O wise Cyril, you have enlightened everyone by your teachings. You are the harp of the Spirit. Intercede to Christ our God for the salvation of our souls.
Kontakion of Cyril, Abp. Of Alexandria in the Fourth Tone
Thou with the power of Christ Saviour's divine words didst rend asunder all the webs of the heresies and didst enrich the Church by cutting down the tares of profane Nestorius, O our blest Father Cyril; wherefore, in Christ's presence now with the choirs of the Angels thou intercedest fervently with Him to grant forgiveness of failings to all of us.
