Ambrose is ranked with the great Western Christian leaders of the time: Augustine, St. [[Jerome]], St. [[Gregory the Great]], and St. Hilary of Poitiers. Ambrose was most known for his administrative talents, given his education and early experience before becoming a bishop. Yet, like Hilary he was an Alexandrian and was in the forefront in the doctrinal issues of the day, particularly those concerning Arianism. His sermons were famous and were influential in the conversion of Augustine. His endeavors in [[hymnography|hymn writing]] became models of hymns of dignified simplicity for future times. Ambrose is credited with introducing [[antiphonal chant]]ing wherein one choir alternates with another. Of particular note is that Ambrose baptized Augustine, his celebrated convert.
