Hilary, who they claim fell short of Ambrose's administrative excellence but demonstrated greater theological ability. He succeeded as a theologian despite his juridical training and his comparatively late handling of biblical and doctrinal subjects. Ambrose's intense episcopal consciousness furthered the growing doctrine of the Church and its sacerdotal ministry, while the prevalent asceticism of the day, continuing the Stoic and Ciceronian training of his youth, enabled him to promulgate a lofty standard of Christian ethics. Thus we have the De officiis ministrorum, De viduis, De virginitate and De paenitentia. Ambrose displayed a kind of liturgical flexibility that kept in mind that liturgy was a tool to serve people in worshiping God, and ought not to become a rigid entity that is invariable from place to place. His advice to Augustine of Hippo on this point was to follow local liturgical custom. "When I am at Rome, I fast on a Saturday; when I am at Milan, I do not. Follow the custom of the church where you are." Thus Ambrose refused to be drawn into a false conflict over which particular local church had the "right" liturgical form where there was no substantial problem. His advice has remained in the English language as the saying, "When in Rome, do as the Romans do." One interpretation of Ambrose's writings is that he was a Christian universalist. It has been noted that Ambrose's theology was significantly influenced by that of Origen and Didymus the Blind, two other early Christian universalists. One quotation cited in favor of this belief is: One could interpret this passage as being another example of the mainstream Christian belief in a general resurrection (that both those in Heaven and in Hell undergo a bodily resurrection), or an allusion to purgatory (that some destined for Heaven must first undergo a phase of purification). Several other works by Ambrose clearly teach the mainstream view of salvation. For example: "The Jews feared to believe in manhood taken up into God, and therefore have lost the grace of redemption, because they reject that on which salvation depends." Giving to the poor In De Officiis, the most influential of his surviving works, and one of the most important texts of patristic literature, he reveals his views connecting justice and generosity by asserting these practices are of mutual benefit to the participants. Ambrose draws heavily on Cicero and the biblical book of Genesis for
