AMBROSE of MILAN, born to a Christian family in Trier, St. Ambrose was the son of the Praetorian Prefect of Gaul. He followed his father in an administrative career culminating in his appointment as governor of Aemilia-Liguria, with his seat at Milan. Upon the repose of the Arian Bishop of Milan, Auxeminus (374), St. Ambrose was chosen bishop by acclimation, even though he was still a catechumen. Initially he refused, but final accepted, and was baptised, and ordained. St. Ambrose gained fame as a preacher, a passionate defender of orthodoxy against Arianism, and was an important figure in the conversion of St. Augustine (28th August). He is credited with introducing a great deal of Eastern theology to the West, and encouraging monasticism. St. Ambrose introduced antiphonal singing, into the Western Church, was instrumental in making hymns an integral part of the Western Liturgy, and is believed to be the author of the Te Deum.
Troparion of St. Ambrose of Milan Tone IV
In truth you were revealed to your flock as a rule of faith,
an image of humility and a teacher of abstinence;
your humility exalted you;
your poverty enriched you.
Hierarch Father Ambrose,
entreat Christ our God
that our souls may be saved.
Kontakion of St. Ambrose of Milan Tone III
You shone forth with divine doctrine eclipsing the deception of Arius,
shepherd and initiate of the mysteries, Ambrose.
you worked miracles through the power of the Spirit,
healing various passions;
righteous father, entreat Christ our God to grant us His great mercy.
