Irmos: Thou hast come, O my Lord, as a light into the world: a holy light turning from the darkness of ignorance those who hymn Thee with faith.
Theotokion: He Who wrought all things in wisdom through His will, desiring to renew man, O Virgin, made His abode in thy womb.
Having attained a mind resplendent with immaterial light, O blessed Ambrose, thou hast emitted rays of healing and miracles.
Thou didst raise thyself up as a sacred dwelling place of the Spirit, O divinely inspired Ambrose, and didst raze the temples of idolatry.
Emperors were put to shame by thee, shining with the effulgence of the greatest of virtues, and their restrictions did not cause thy tongue to falter.
