St. Ambrose was a bishop of Milan who became one of the most influential ecclesiastical figures of the 4th century. He was one of the four original doctors of the Church.

Ambrose was born around 339 in what is now France, the son of the Roman prefect of Gaul.  Following in his father’s footsteps, Ambrose embarked upon a career in law and politics and by 370 AD, he had become the Imperial governor ofNorthern Italy.  When the seat of Bishop of Milan became vacant in 374, the people demanded that Saint Ambrose be made their bishop.  The neighboring bishops and the Emperor convinced him to accept this call as the will of God, and so the catechumen Ambrose was baptized and ordained first deacon, then priest, then bishop, all in a single week!

This politician-turned churchman was profoundly aware of his lack of preparation for this great responsibility and so set himself immediately to prayer and the study of Scripture.  His deep spirituality and love of God’s Word married together with the oratorical skill acquired in law and politics made St. Ambrose one of the greatest preachers of the early church.

Around 385, an ambitious professor of public speaking named Augustine came to hear Saint Ambrose preach in order to study his technique, and in the process, was attracted to the Catholic faith.  In 386 Augustine was baptized by St. Ambrose and went on to become bishop of Hippo in North Africa.  Ambrose and his pupil, Augustine, together with St. Jerome and St. Gregory the Great, make up the four original Doctors of the Latin Church.  Saint Ambrose, the great bishop ofMilan, died on Holy Saturday (April 4) in the year 397 AD.  His feast day in the Roman calendar is December 7, the day he was ordained bishop.

From the Roman liturgy for the Feast of St. Ambrose: “Lord, you made Saint Ambrose an outstanding teacher of the Catholic faith and gave him the courage of an apostle.  Raise up in your Church more leaders after your own heart, to guide us with courage and wisdom.  We ask this through our Lord Jesus Christ, your Son, who lives and reigns with you and the Holy Spirit, one God forever and ever.  Amen.”

” No one heals himself by wounding another.”
