Verified Facts
- He was elected Bishop of Milan by a rioting crowd while he was still a catechumen (unbaptized learner). He was baptized, ordained, and consecrated bishop all within one week—one of the most extraordinary career changes in history.
- After Emperor Theodosius massacred 7,000 civilians in Thessalonica in 390 CE, Ambrose publicly excommunicated him and refused him communion until he performed months of public penance. This was the first time a churchman had successfully asserted moral authority over a Roman Emperor.
- He was the direct catalyst for Augustine's conversion. Augustine came to Milan as a skeptical rhetoric professor and was gradually won over by Ambrose's allegorical preaching, which showed him that Christianity could be intellectually sophisticated.
- He introduced Eastern-style hymn singing to the Western church. Several hymns attributed to him (the "Ambrosian hymns") are still sung today, making him one of the founders of Western church music.
