Irmos: Seated in glory upon the throne of the Godhead, Jesus most divine hath come on a light cloud, and with His incorrupt arm hath saved those who cry: Glory to Thy power, O Christ!
Thou, O wise father, didst preach the one beginningless Essence in three Hypostases, Each with its own properties, separate yet indivisible, unified yet not commingled, one in will and divinity.
Theotokion: Thou art become more comely than all the magnificence of the angels, O Maiden, in that thou hast given birth unto their Creator and Lord, Who was incarnate of thine all-pure blood and delivereth all who glorify Him.
Possessed of chaste thought and a mind most chaste, O most blessed father, thou didst not admit any change or confusion of the two immutably united natures in the one, only-begotten Christ.
Divinely illumined by the enlightenment of the Spirit, thou didst set at nought the wicked insanity of Nestorius, who with his will and reason preached the fusion into one nature of the two natures of Christ.
With the fire of thy teachings, O divinely wise and venerable father, thou didst utterly consume Pyrrhus, who denied that in Christ there are two volitions which are of themselves of different essences, and likewise that there are two energies.
