“…Likewise, during the era of the Gregorian reforms in the late 11 th century, the key papalist claim that 'spiritual rule' must have primacy over or be acknowledged as higher than 'secular rule' would -viewed in terms of this conception -be acceptable if by 'spiritual rule' was meant 'sacred reign' or 'spiritual reign', for king and bishop are both subject in their respective realms to this 'reign from above' and both need to be informed, guided and enriched by the eternal font of righteousness. Alexander D'entreves contrasts the way in which Aquinas endeavored to reconcile the realms of nature and grace with the way in which Marsilius draws between them 'a clear-cut and impassable line of demarcation' 20 and David Henreckson is likewise convinced that Marsilius advanced 'the most pronounced argument for the divorce between politics and the supernatural', that he 'developed a concept of political authority which explicitly rejected any connection to the supernatural realm of grace', 21 that 'the priest should help his flock toward eternal salvation and not confuse them by meddling in earthly affairs' and that he embraced the voluntarism of his contemporary William of Ockham in claiming that 'will' is the essence of law. Secular rule, then, is in a special sense spiritual/sacred; as the ruling instrument (and relatively autonomous 'means') of the divine reign, it is intrinsically spiritual/sacred, or at least intrinsically oriented to the spiritual/sacred, so that to regard 'spiritual rule' and 'secular rule' as separate and distinct and in such a way that one might be deemed to be higher or lower than the other, is to separate the inseparable.…”
