The De officiis of Ambrose of Milan (c. 339-397) is one of the most important texts of Latin Patristic literature. Modelled on the De Officiis of Cicero, it sets out Ambrose's ethical vision for his clergy, synthesizing ancient Stoic assumptions on virtue and expediency with Biblical patterns of humility, charity, and self-denial to present a paradigm of a church hierarchy capable of making the right impact on its social world. Ambrose aspires to demonstrate that the age of profound principles is now available.This new edition constitutes the first Modern English translation of Ambrose's Latin. The Text and Translation in Volume 1 are accompanied by a detailed Commentary (Volume 2) that concentrates on Ambrose's debts to Cicero and his attempts to renovate his philosophical inheritance. An extensive Introduction analyses his ethical ideals and sets them in their social context.
