The most powerful alliance was that with the papal court at Rome. Here Lanfranc could serve his adopted country to good effect. Hildebrand's power was making itself felt more and more, and it was he who most ardently desired and fostered the claim of the Church to a mastery of all the crowns of Christendom. "The decree went forth, which declared Harold to be a usurper and William to be the lawful claimant of the English crown. It would even seem that it declared the English king and all his followers to be cut off from the communion of the faithful. William was sent forth as an avenger to chastise the wrong and perjury of his faithless vassal. But he was also sent forth as a missionary, to guide the erring English into the true path, to teach them due obedience to Christ's vicar, and to secure a more punctual payment of the temporal dues of his apostle. The cause of the invasion was blessed, and precious gifts were sent as the visible exponents of the blessing. A costly ring was sent, containing a relic, holier, it may be, than any on which Harold had sworn—a hair of the prince of the apostles. And with the ring came a consecrated banner."[10] These were, after all, more formidable weapons than the Norman arrows. They inspired [Pg287] not only courage, but a sense of duty and of righteous service of God. Alas for poor humanity that lends itself so readily to wrongdoing, and even hopes to win heaven by making this earth a place of bloodshed and treachery. Now, William had something besides English lands and high places for knight and priest alike on conquered soil—he could give security and eminence in the world to come. Heaven itself had been promised by its chief representative on earth to those who would fight for the Duke of Normandy against England. Hildebrand had made a last appeal to the holy assembly of cardinals when he told the story of the profaned relics and Harold's broken oath, and had urged the willing fathers of the church to consider how pious and benevolent it would be to Christianize the barbarous and heathen Saxons. Nobody took pains to remember that the priesthood of England owned a third of the English lands, and ruled them with a rod of iron. So long as England would not bend the knee to Rome, what did all that matter?
