What difficulties did St Ambrose face?

St. Ambrose faced significant challenges during his tenure as Bishop of Milan, including conflicts with Arianism, which was a major theological controversy of the time. He also encountered political tension with the Roman emperors, particularly with Theodosius I, regarding church-state relations and the enforcement of Christian orthodoxy. Additionally, Ambrose had to navigate the complexities of a diverse and often divided Christian community, advocating for the rights of the Church against secular authority while promoting unity among believers.
