Feast of St. Ambrose
Monday, December 7, 2026
The Feast of St. Ambrose, celebrated on December 7, honors Saint Ambrose (c. 339-397 AD), the Bishop of Milan and one of the four original Doctors of the Latin Church. Born into a Roman Christian family in Trier, present-day Germany, Ambrose was initially a provincial governor before being unexpectedly elected Bishop of Milan by popular acclaim while still a catechumen. As bishop, he became a towering figure of 4th-century Christianity, renowned for his theological writings, his eloquent preaching, and his steadfast opposition to Arianism. Ambrose is credited with developing the Ambrosian chant and the Ambrosian rite still used in the Archdiocese of Milan. He famously baptized Saint Augustine of Hippo and played a crucial role in the conversion of the Roman Empire. His feast day is celebrated with particular solemnity in Milan, of which he is the patron saint.
History
Ambrose was born around 339 in Trier to a Christian family of Roman nobility. Following his father's death, he moved to Rome where he studied law and rhetoric. In 370, he was appointed governor of Liguria and Emilia with his seat in Milan. When the Arian bishop of Milan died in 374, Ambrose intervened to maintain peace between Orthodox and Arian factions. During his speech, a child reportedly cried 'Ambrose for bishop,' and the crowd took it as divine will. Though only a catechumen, he was baptized and consecrated bishop within a week. Ambrose served as bishop for 23 years, during which he wrote extensively on theology and ethics, composed hymns, and wielded significant political influence, notably compelling Emperor Theodosius I to do public penance.
How It's Celebrated
The Feast of St. Ambrose is celebrated with particular grandeur in Milan, where a solemn pontifical Mass is held at the Basilica of Sant'Ambrogio, which houses the saint's relics. The Ambrosian rite, the traditional liturgical rite of Milan, is used for these services. Across Italy and Germany, churches named after St. Ambrose hold special masses, and the day is marked by processions featuring the Ambrosian chants he helped establish. In his birthplace of Trier, Germany, commemorations include ecumenical services and cultural events. The festival also includes the blessing of honey and beeswax candles, referencing the legend of bees settling on Ambrose's mouth as an infant without harming him.
