St. Ambrose (c. 340–397 AD) was the Bishop of Milan and a Doctor of the Church, known for his defense of Nicene Christianity against Arianism. Born into a prominent Roman family, he pursued a career in law and governance before his unexpected election as bishop, despite being unbaptized. A skilled theologian and eloquent orator, he influenced both church and state, famously calling Emperor Theodosius I to repentance after the massacre at Thessalonica. Ambrose’s hymns, writings, and pastoral work left a lasting legacy, including his role in the conversion and baptism of St. Augustine. His feast day is celebrated on December 7.
