The monks of Cluny and others like them saw two groups that had to be "transformed" before all others: the soldiers and the clergy. In order to do this work properly, they needed a reformed Papacy on their side. Dr. John Rao shows how the Papacy, by the time of Pope Gregory VII, had been so transformed that it actually took charge of the whole movement of sanctifying society at large.
