An energetic defender of the faith, he was not afraid to oppose the Roman Emperor when such was called for. But Ambrose, in this biography by noted scholar Cesare Pasini, comes across above all as a Bishop. The reader will find here a pastor who knew how to enliven his community with his imaginative preaching and solid catechists, with the celebrations surrounding the sacramental rites, with his dedicated work for justice profoundly animated by charity, and with a sense of equilibrium in his judgments based on ethics and Christian spirituality. Often this biography cites from the ancient testimonies which history has left us about Ambrose himself. In this way the reader can better penetrate the soul of the soul of the protagonist, enjoying the captivating words of the Bishop himself. This work of Pasini makes a serious contribution to our understanding of this highly acclaimed and most beloved patron saint of the Milanese Church.
