When William's profaneness therefore returned to him with his health, he was soon engaged in controversies with this austere prelate. There was at that time a schism in the church between Urban and Clement, who both pretended to the papacy [i]; and Anselm, who, as Abbot of Bec, had already acknowledged the former, was determined, without the king's consent, to introduce his authority into England [k]. William, who, imitating his father's example, had prohibited his subjects from recognizing any pope whom he had not previously received, was enraged at this attempt; and summoned a synod at Rockingham, with an intention of deposing Anselm: but the prelate's suffragans declared, that without the papal authority, they knew of no expedient for inflicting that punishment on their primate [l]. The king was at last engaged by other motives to give the preference to Urban's title: Anselm received the pall from that pontiff; and matters seemed to be accommodated between the king and the primate [m], when the quarrel broke out afresh from a new cause. William had undertaken an expedition against Wales, and required the archbishop to furnish his quota of soldiers for that service; but Anselm, who regarded the demand as an oppression on the church, and yet durst not refuse compliance, sent them so miserably accoutred, that the king was extremely displeased, and threatened him with a prosecution [n]. Anselm, on the other hand, demanded positively that all the revenues of his see should be restored to him; appealed to Rome against the king's injustice [o]; and affairs came to such extremities, that the primate, finding it dangerous to remain in the kingdom, desired and obtained the king's permission to retire beyond sea. All his temporalities were seized [p]; but he was received with great respect by Urban, who considered him as a martyr in the cause of religion, and even menaced the king on account of his proceedings against the primate and the church, with the sentence of excommunication. Anselm assisted at the council of Bari, where, besides fixing the controversy between the Greek and Latin churches, concerning the procession of the Holy Ghost [q], the right of election to church preferments was declared to belong to the clergy alone, and spiritual censures were denounced against all ecclesiastics, who did homage to laymen for their sees or benefices, and against all laymen who exacted it [r]. The right of homage, by the feudal customs, was, that the vassal should throw himself on his knees, should put his joined hands between those of his superior, and should in that posture swear fealty to him [s]. But the council declared it execrable, that pure hands, which could create God, and could offer him up as a sacrifice for the salvation of mankind, should be put, after this humiliating manner, between profane hands, which, besides being inured to rapine and bloodshed, were employed day and night in impure purposes, and obscene contacts [t].
