Gregory VII. also took the field against the dissolute and prodigal king of France, Philip I., and threatened him, because of simony, with interdict and deposition. His success here, however, was comparatively small. Philip avowedly submitted to the papal decree, but did not in the least alter his conduct, and Gregory felt that it was not prudent to push matters to an extremity. He showed himself more indulgent toward the powerful William the Conqueror of England, although this prince ruled the church of his dominions with an iron hand, pronounced all church property to be freehold, and was scarcely less guilty of simony than the kings of Germany and France. Yet the pope himself, who hoped to secure the aid of his arms against Henry IV., and sought therefore to dazzle him with the prospect of the imperial throne, winked at his delinquencies, and loaded him with expressions of his good-will. The primate of England, too, the powerful Conqueror’s right-hand supporter, Lanfranc of Canterbury, who bore a grudge against Gregory because of his patronage of the heretic Berengarius [Berengar] (§ 101, 2), showed no special zeal for the reforms advocated by the pope. At a synod held at Winchester in A.D. 1076, the law of celibacy was enforced, with this limitation, however, that those of the secular clergy who were already married should not be required to put away their wives, but no further marriages among them were to be permitted.[275] § 96.9. =The Central Idea in Gregory’s Policy= was the establishment of a universal theocracy, with the pope as its one visible head, the representative of Christ upon earth, who as such stands over the powers of the world. Alongside of it, indeed, the royal authority was to stand independently as one ordained of God, but it was to confine itself strictly to temporal affairs, and to be directed by the pope in regard to whatever might be partly within and partly without these lines. All states bearing the Christian name were to be bound together as members of one body in the great papal theocracy which had superior to it only God and His law. The princes must receive consecration and Divine sanction from the spiritual power; they are “by the grace of God,” not immediately, however, but only mediately, the church as the middle term stands between them and God. The pope is their arbiter and highest liege lord, whose decisions they are under obligation unconditionally to obey. Royalty stands related to the papacy as the moon to the sun, from which she receives her light and warmth. The church, which lends to the power of the world her Divine authority, can also withdraw it again when it is being misused. When this is done, the obligation of subjects to obey also ceases. Gregory began this gigantic work, not so much to raise himself personally to the utmost pinnacle of power, but rather to save the church from destruction.
