Born around 340 AD, he initially pursued a career in law and politics. However, after a significant event where he intervened in a conflict between Arian and Orthodox Christians, he was hailed by the people and subsequently became the bishop of Milan. This marked the start of his influential role in the Church, where he became a staunch defender of Christianity against paganism and Arianism. Ambrose was also a prolific writer and is credited with several works that contributed to Christian theology. His sermons and letters addressed various theological issues, emphasizing the importance of virtuous living and the moral responsibilities of Christians.

His efforts not only established him as a spiritual leader but also as a key figure in the development of Western Christianity.

He asserted the independence of the Church from secular authorities, famously confronting Emperor Theodosius I over the massacre at Thessalonica.
