Saint Ambrose was born in France to wealthy Roman parents in 340 AD. When he was mature, and his father had passed away, he moved to Rome, where he finished his education, and became a governor. While still a catechumen (an unbaptized Christian), the bishop of Milan died, and he was chosen for the position. At the order of the emperor he was baptized and appointed as the new bishop, the office he would hold until his death.
Once he became a bishop, he gave away all his wealth and property for church use and to help the poor. He then took on a strict ascetic life and devoted himself to his work.
St. Ambrose's preaching quickly became famous and he attracted many people to his church. He is well-known for his writings in which he both explains and defends the true character of the Christian faith. He also wrote on the moral and education requirements of priests.

Saint , bishop of Milan from 374, wrote, composed, and imposed orthodoxy on the early Christian Church.
This ecclesiastical figure of the 4th century most influenced. He served as consular prefect of Liguria and Emilia, headquartered, before popular acclamation. Ambrose staunchly opposed Arianism, and people accused him of fostering persecutions of Jews and pagans.
Tradition credits Ambrose with promoting "antiphonal chant", a style in which one side of the choir responds alternately, as well as Veni redemptor gentium, a hymn of Advent.
Ambrose ranks of the four original doctors of the Church, and the patron. He notably influenced Saint Augustine of Hippo.
Big fan of St. Ambrose, has some phenomenal stuff on justification. He's not easy to classify in one camp or another on every matter, but I think I'd agree with him on baptism and justification. I disagree with him in other areas, but he's still worth reading there.
