The variety of religious communities present in today’s western-European countries, and their subsequent political impact, urgently calls for a new model of articulation between church and state, religion and politics. This essay makes some suggestions for one such model based on Saint Augustine’s sermons and letters. In those writings, Augustine shows us the everyday political practices of his Christian community – practices based on which this article proposes a model where both the religious communities are entitled to be present in (...) the public arena, and the political authorities have the tools to assure peace and order. For that reason, revisiting Augustine’s work is crucial for a contemporary reflection on the relationship between state and church. Finally, this essay also systematizes the Augustinian distribution of political tasks between Monks, Christian laity, Christian magistrates, and Bishops. (shrink)
