St. Benedict helped save Christian culture. Alasdair MacIntyre, at the end of his 1981 book After Virtue writes:
A crucial turning point in that earlier history occurred when men and women of good will turned aside from the task of shoring up the Roman imperium and ceased to identify the continuation of civility and moral community with the maintenance of that imperium. What they set themselves to achieve instead . . . was the construction of new forms of community within which the moral life could be sustained so that both morality and civility might survive the coming ages of barbarism and darkness. If my account of our moral condition is correct, we ought also to conclude that for some time now we too have reached that turning point. . . . This time, however, the barbarians are not waiting beyond the frontiers; they have already been governing us for quite some time. And it is our lack of consciousness of this that constitutes part of our predicament. We are waiting not for a Godot, but for another — doubtless quite different — St. Benedict.
Read Fulgens Radiatur. Part of those "new forms of community" must be the reunion of Christians, in the face of surrounding darkness and decay.
