Life

Aurelius Ambrosius was born around the year 340 in Trier to a family of senatorial rank; his father was praetorian prefect of Gaul, and his sister Marcellina was a consecrated virgin. Educated at Rome in rhetoric and law, he rose to become governor of the provinces of Liguria and Emilia, with his seat at Milan. When the bishop of Milan died around 374, the Arian and Nicene factions could not agree on a successor. A voice cried out in the church — tradition says it was a child's voice — calling for the unbaptized governor. The crowd took it up, and Ambrose was elected bishop by acclamation.

He was baptized, ordained through every grade of the clergy in rapid succession, and consecrated within eight days. He immediately gave away his personal wealth to the poor and his property to his sister, and devoted himself with an intensity born of necessity to theological study — reading Greek fluently, he made himself a faithful transmitter of Eastern theology, particularly the Alexandrian tradition, to the Latin West. He also introduced the singing of hymns in the antiphonal Eastern style into his congregation, becoming in the process the founder of hymnody in the Western Church.

His episcopate was marked by confrontations with imperial power. When the Empress Justina demanded basilicas in Milan for Arian worship, Ambrose and his congregation occupied the churches for weeks, singing through the nights the hymns he had composed for the occasion. When the Emperor Theodosius massacred thousands in Thessalonica in reprisal for a riot, Ambrose refused him communion until he had done public penance — and the most powerful man in the Roman world submitted. Above all he was the bishop who baptized Augustine at the Easter Vigil of 387, opening the eyes of that restless young rhetor to the depths of Scripture and setting in motion the theological legacy that would shape the next millennium. He reposed on April 4, 397. The Orthodox Church honors him on December 7, the feast of his episcopal consecration.
