This is a major biography on one of the most famous Fathers of the early Church. Ambrose of Milan was an energetic defender of the faith who was not afraid to oppose the Roman Emperor when such was called for. But Ambrose, in this biography of Pasini, comes across above all as a Bishop and paster who knew how to enliven his community with imaginative preaching, solid catechesis, sacred liturgies, and a dedication to works of justice animated by charity. The author makes extensive use of ancient testimonies about Ambrose and the writings and other materials handed down to us by Ambrose himself enabling the reader to better penetrate the inner mind and heart of Ambrose.
