St. Ambrose was an archbishop of Milan and one of the most influential figures of the fourth century. He is one of the four original Doctors of the Church and Latin theologians. His writings had a direct influence on St. Augustine, and his intense ecclesiastical awareness expanded and reinforced the Church’s sacerdotal ministry and the high standards of Christian ethics. He furthered fourth-century Mariology, Christology, and soteriology, and allegedly ended Arianism in his diocese, Milan. These volumes of his collected and translated writings bring the intensity of his ancient rhetoric back to the present, allowing us an unusually full glimpse at the early church.
