Professor Gabriel Le Bras, a great pioneer in the field of historical sociology, has spoken of the early medieval Church in a bizarre but effective metaphor as ‘a dismembered body striving to reunite itself’. The essential task of the hierarchy within each national Church was one of coordination—by means of law, doctrine, and the standardization of worship. In the fragmented world of the barbarian kingdoms, the distinctive feature of each episcopate was its ideology of cohesion, the more ardently propounded when social crisis was particularly acute, as in the seventh-century Visigothic kingdom, or the war-torn West Francia of the 830s and 840s. This ideology was, moreover, often intimately associated with movements of monastic reform. Its influence penetrated down into the rural base of society through episcopal visitations, preaching, and provincial councils. To trace all the elements in these complex processes of interaction and change would encompass that much-needed sociology of the early medieval Church which Max Weber did not live to write and no scholar has yet produced. In this paper, as its title implies, my very limited objective is to isolate and examine certain recurrent phenomena and to point to some hitherto unnoticed connections.
