Saint Ambrose of Milan: The Reluctant Bishop and Doctor of the Church — Life, Teachings, and Prayers
Share
Introduction: Who Was Saint Ambrose of Milan?
Saint Ambrose of Milan is one of the four original Doctors of the Western Church — alongside Saints Jerome, Augustine, and Gregory the Great — and one of the most remarkable bishops in the history of Christianity. He was a Roman imperial governor who had never been baptized when the people of Milan acclaimed him as their bishop by popular demand, and who went from catechumen to bishop in eight days. He became one of the greatest preachers, theologians, and church musicians of the ancient world, the man who baptized Saint Augustine of Hippo, and the bishop who dared to excommunicate the Emperor Theodosius the Great for a massacre of civilians — and who made the Emperor do public penance before readmitting him to Communion. He is venerated in both the Orthodox and Catholic traditions as a Father and Doctor of the Church.
Early Life and Imperial Career
Aurelius Ambrosius was born around 339 AD in Augusta Treverorum (present-day Trier, Germany), the son of the Praetorian Prefect of Gaul — one of the highest officials in the Western Roman Empire. He was raised in Rome, received an excellent classical education in rhetoric and law, and rose quickly through the imperial administration. Around 372 AD, the Emperor Valentinian I appointed him as governor of Liguria and Emilia, with his seat in Milan — then the effective capital of the Western Roman Empire.
Ambrose was a capable and respected governor, known for his fairness and his administrative skill. He was a Christian by upbringing and sympathy, but had not yet been baptized — a common practice in the ancient world, where many Christians delayed baptism until late in life. He was about to have that choice made for him.
Election as Bishop
Acclaimed by the People
In 374 AD, the Bishop of Milan died, and the city was immediately plunged into conflict between the Orthodox and Arian factions, each determined to elect one of their own as bishop. Ambrose went to the cathedral to keep order as governor. According to the ancient accounts, a child's voice cried out from the crowd: "Ambrose for bishop!" — and the entire assembly, Orthodox and Arian alike, took up the cry. The man who had come to prevent a riot found himself unanimously elected bishop by acclamation.
Ambrose was horrified. He tried everything to escape the appointment — he fled the city, he had criminals flogged in public to make himself seem unworthy, he even attempted to live openly with women to disqualify himself. None of it worked. The Emperor confirmed the election, and Ambrose submitted. He was baptized, ordained through all the clerical ranks in rapid succession, and consecrated bishop — all within eight days.
Episcopal Ministry
Defender of Orthodoxy
Ambrose immediately gave away his personal fortune to the poor and to the Church and threw himself into the study of theology with the same energy he had brought to his legal career. He became one of the most formidable defenders of Nicene Orthodoxy against Arianism, resisting repeated attempts by the Empress Justina — who favored the Arians — to seize basilicas in Milan for Arian worship. When imperial troops surrounded one of his churches to take it by force, Ambrose and his congregation occupied it and sang hymns continuously until the troops withdrew. It was during this standoff that he introduced antiphonal hymn-singing to the Western Church — a practice that spread throughout Christendom and earned him the title of father of Western church music.
The Excommunication of Theodosius
The most dramatic episode of Ambrose's episcopate was his confrontation with the Emperor Theodosius the Great after the Massacre of Thessaloniki in 390 AD. Theodosius had ordered the massacre of thousands of civilians in Thessaloniki in retaliation for a riot — a decision he made in anger and later deeply regretted. Ambrose wrote him a private letter refusing to celebrate the Eucharist in his presence until he had done public penance. Theodosius submitted. He appeared at the cathedral in Milan stripped of his imperial insignia, prostrated himself before the congregation, and confessed his sin publicly. Ambrose readmitted him to Communion. The episode established for all time the principle that the Church's moral authority stands above the power of the state — even the Roman Emperor must answer to God.
The Baptism of Augustine
Among the many souls Ambrose brought to the faith, none was more consequential than Augustine of Hippo — the greatest theologian in the history of the Western Church. Augustine arrived in Milan as a professor of rhetoric, skeptical and restless. He began attending Ambrose's sermons out of professional interest in his oratorical technique — and found himself drawn irresistibly into the faith. Ambrose baptized Augustine at the Easter Vigil of 387 AD. The fruit of that baptism changed the course of Western Christianity.
Theological and Musical Legacy
Ambrose's theological writings — on the Holy Spirit, on the Virgin Mary, on the sacraments, and on the Christian life — are among the most important of the patristic era. His hymns, written in a simple four-line meter that could be sung by congregations, introduced a new form of liturgical poetry to the Western Church. The "Ambrosian" style of hymnody shaped Western church music for centuries, and several of his hymns are still sung today. The Ambrosian Rite — a distinct liturgical tradition used in the Archdiocese of Milan to this day — bears his name.
Repose
Saint Ambrose reposed in the Lord on April 4, 397 AD, at approximately 57 years of age. He died on Holy Saturday, having celebrated the liturgies of Holy Week for the last time. He was buried beneath the altar of the Basilica of Sant'Ambrogio in Milan — the church he had built — where his relics rest to this day alongside those of the martyrs Gervasius and Protasius, whose bodies he had miraculously discovered.

Prayers to Saint Ambrose
Troparion (Tone 4)
O holy hierarch Ambrose, thou wast chosen by God from the ranks of the imperial governors to shepherd His flock in Milan. Thou didst defend the Orthodox faith against heresy, rebuke the powerful without fear, and fill the Church with the beauty of thy hymns. Intercede with Christ our God that He may grant us courage, wisdom, and salvation.
Prayer for Courage to Speak the Truth
O holy hierarch Ambrose of Milan, Doctor of the Church and fearless shepherd: you who made an emperor do penance, who occupied your own church rather than surrender it to heresy, and who were called to the episcopate before you were even baptized — intercede for me before the throne of God. Grant me a share of your courage to speak the truth without fear of consequences, your wisdom to know when to speak and when to be silent, and your humility to submit to God's call even when it leads where I would not choose to go. Help me to use whatever gifts and position I have been given entirely in the service of God and His Church. O holy Ambrose, pray to God for us. Amen.
