Ecclesiastical administrative accomplishments.
An imperial court frequently sat in Milan. In confrontations with this court, Ambrose showed a directness that combined the republican ideal of the prerogatives of a Roman senator with a sinister vein of demagoguery. In 384 he secured the rejection of an appeal for tolerance by pagan members of the Roman senate, whose spokesman, Quintus Aurelius Symmachus, was his relative (Letters 17, 18). In 385–386 he refused to surrender a church for the use of Arian heretics. In 388 he rebuked the emperor Theodosius for having punished a bishop who had burnt a Jewish synagogue. In 390 he imposed public penance on Theodosius for having punished a riot in Thessalonica by a massacre of its citizens. These unprecedented interventions were palliated by Ambrose’s loyalty and resourcefulness as a diplomat, notably in 383 and 386 by his official visits to the usurper Maximus at Trier. In his letters and in his funeral orations on the emperors Valentinian II and Theodosius—De obitu Valentiniani consolatio (392) and De obitu Theodosii (395)—Ambrose established the medieval concept of a Christian emperor as a dutiful son of the church “serving under orders from Christ,” and so subject to the advice and strictures of his bishop.
