His contests with the Church, concerning the right of investiture, were more obstinate and more dangerous. As this is an affair that troubled all Europe as well as England, and holds deservedly a principal place in the story of those times, it will not be impertinent to trace it up to its original. In the early times of Christianity, when religion was only drawn from its obscurity to be persecuted, when a bishop was only a candidate for martyrdom, neither the preferment, nor the right of bestowing it, were sought with great ambition. Bishops were then elected, and often against their desire, by their clergy and the people: the subordinate ecclesiastical districts were provided for in the same manner. After the Roman Empire became Christian, this usage, so generally established, still maintained its ground. However, in the principal cities, the Emperor frequently exercised the privilege of giving a sanction to the choice, and sometimes of appointing the bishop; though, for the most part, the popular election still prevailed. But when, the Barbarians, after destroying the Empire, had at length submitted their necks to the Gospel, their kings and great men, full of zeal and gratitude to their instructors, endowed the Church with large territories and great privileges. In this case it was but natural that they should be the patrons of those dignities and nominate to that power which arose from their own free bounty. Hence the bishoprics in the greatest part of Europe became in effect, whatever some few might have been in appearance, merely donative. And as the bishoprics formed so many seigniories, when the feudal establishment was completed, they partook of the feudal nature, so far as they were subjects capable of it; homage and fealty were required on the part of the spiritual vassal; the king, on his part, gave the bishop the investiture, or livery and seizin of his temporalities, by the delivery of a ring and staff. This was the original manner of granting feudal property, and something like it is still practised in our base-courts. Pope Adrian confirmed this privilege to Charlemagne by an express grant. The clergy of that time, ignorant, but inquisitive, were very ready at finding types and mysteries in every ceremony: they construed the staff into an emblem of the pastoral care, and the ring into a type of the bishop's allegorical marriage to his church, and therefore supposed them designed as emblems of a jurisdiction merely spiritual. The Papal pretensions increased with the general ignorance and superstition; and the better to support these pretensions, it was necessary at once to exalt the clergy extremely, and, by breaking off all ties between them and their natural sovereigns, to attach them wholly to the Roman see. In pursuance of this project, the Pope first strictly forbade the clergy to receive investitures from laymen, or to do them homage. A council held at Rome entirely condemned
