In the ancient constitution of the Christian church, the bishop of each diocese was elected by the joint votes of the clergy and of the people of the episcopal city. The people did not long retain their right of election; and while they did retain it, they almost always acted under the influence of the clergy, who in such spiritual matters appeared to be their natural guides. The clergy, however, soon grew weary of the trouble of managing them, and found it easier to elect their own bishops themselves. The abbot, in the same manner, was elected by the monks of the monastery, at least in the greater part of the abbacies. All the inferior ecclesiastical benefices comprehended within the diocese were collated by the bishop, who bestowed them upon such ecclesiastics as he thought proper. All church preferments were in this manner in the disposal of the church. The sovereign, though he might have some indirect influence in those elections, and though it was sometimes usual to ask both his consent to elect and his approbation of the election, yet had no direct or sufficient means of managing the clergy. The ambition of every clergyman naturally led him to pay court not so much to his sovereign as to his own order, from which only he could expect preferment.

Through the greater part of Europe the Pope gradually drew to himself first the collation of almost all bishoprics and abbacies, or of what were called Consistorial benefices, and afterwards, by various machinations and pretences, of the greater part of inferior benefices comprehended within each diocese; little more being left to the bishop than what was barely necessary to give him a decent authority with his own clergy. By this arrangement the condition of the sovereign was still worse than it had been before. The clergy of all the different countries of Europe were thus formed into a sort of spiritual army, dispersed in different quarters, indeed, but of which all the movements and operations could now be directed by one head, and conducted upon one uniform plan. The clergy of each particular country might be considered as a particular detachment of that army, or which the operations could easily be supported and seconded by all the other detachments quartered in the different countries round about. Each detachment was not only independent of the sovereign of the country in which it was quartered, and by which it was maintained, but dependent upon a foreign sovereign, who could at any time turn its arms against the sovereign of that particular country, and support them by the arms of all the other detachments.

Those arms were the most formidable that can well be imagined. In the ancient state of Europe, before the establishment of arts and manufactures, the wealth of the clergy gave them the same sort of influence over the common people which that of the great barons gave them over their respective vassals, tenants, and retainers. In the great landed estates which the mistaken piety both of princes and private persons had bestowed upon the church, jurisdictions were established of the same kind with those of the great barons, and for the same reason. In those great landed estates, the clergy, or their bailiffs, could easily keep the peace without the support or assistance either of the king or of any other person; and neither the king nor any other person could keep the peace there without the support and assistance of the clergy. The jurisdictions of the clergy, therefore, in their particular baronies or manors, were equally independent, and equally exclusive of the authority of the king's courts, as those of the great temporal lords. The tenants of the clergy were, like those of the great barons, almost all tenants at will, entirely dependent upon their immediate lords, and therefore liable to be called out at pleasure in order to fight in any quarrel in which the clergy might think proper to engage them. Over and above the rents of those estates, the clergy possessed in the tithes, a very large portion of the rents of all the other estates in every kingdom of Europe. The revenues arising from both those species of rents were, the greater part of them, paid in kind, in corn, wine, cattle poultry, etc. The quantity exceeded greatly what the clergy could themselves consume; and there were neither arts nor manufactures for the produce of which they could exchange the surplus. The clergy could derive advantage from this immense surplus in no other way than by employing it, as the great barons employed the like surplus of their revenues, in the most profuse hospitality, and in the most extensive charity. Both the hospitality and the charity of the ancient clergy, accordingly, are said to have been very great. They not only maintained almost the whole poor of every kingdom, but many knights and gentlemen had frequently no other means of subsistence than by travelling about from monastery to monastery, under pretence of devotion, but in reality to enjoy the hospitality of the clergy. The retainers of some particular prelates were often as numerous as those of the greatest lay-lords; and the retainers of all the clergy taken together were, perhaps, more numerous than those of all the lay-lords. There was always much more union among the clergy than among the
