Meanwhile a dispute on a question of church patronage arose between the primate and a tenant-in-chief of the Crown, named William of Eynesford. Thomas excommunicated his opponent without observing the custom which required him to give notice to the king before inflicting spiritual penalties on one of his tenants-in-chief.[80] Henry indignantly bade him withdraw the sentence; Thomas refused, saying “it was not for the king to dictate who should be bound or who loosed.”[81] The answer was indisputable in itself; but it pointed directly to the fatal subject on which the inevitable quarrel must turn: the relations and limits between the two powers of the keys and the sword.

Diceto explains, to guard the king against the risk of unwittingly associating with excommunicates. [81] Will. Fitz-Steph. as above. Almost from his accession Henry seems to have been in some degree contemplating and preparing for those great schemes of legal reform which were to be the lasting glory of his reign. His earliest efforts in this direction were merely tentative; the young king was at once too inexperienced and too hard pressed with urgent business of all kinds, at home and abroad, to have either capacity or opportunity for great experiments in legislation. Throughout the past nine years, however, the projects which floated before his mind’s eye had been gradually taking shape; and now that he was at last freed for a while from the entanglements of politics and war, the time had come when he might begin to devote himself to that branch of his kingly duties for which he probably had the strongest inclination, as he certainly had the highest natural genius. He had by this time gained enough insight into the nature and causes of existing abuses to venture upon dealing with them systematically and in detail, and he had determined to begin with a question which was allowed on all hands to be one of the utmost gravity: the repression of crime in the clergy.
