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, of 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 lay-lords. The former were under a regular discipline and subordination to the papal authority. The latter were under no regular discipline or subordination, but almost always equally jealous of one another, and of the king. Though the tenants and retainers of the clergy, therefore, had both together been less numerous than those of the great lay-lords, and their tenants were probably much less numerous, yet their union would have rendered them more formidable. The hospitality and charity of the clergy, too, not only gave them the command of a great temporal force, but increased very much the weight of their spiritual weapons. Those virtues procured them the highest respect and veneration among all the inferior ranks of people, of whom many were constantly, and almost all occasionally, fed by them. Everything belonging or related to so popular an order, its possessions, its privileges, its doctrines, necessarily appeared sacred in the eyes of the common people; and every violation of them, whether real or pretended, the highest act of sacrilegious wickedness and profaneness. In this state of things, if the sovereign frequently found it difficult to resist the confederacy of a few of the great nobility, we cannot wonder that he should find it still more so to resist the united force of the clergy of his own dominions, supported by that of the clergy of all the neighbouring dominions. In such circumstances, the wonder is, not that he was sometimes obliged to yield, but that he ever was able to resist.

The privileges of the clergy in those ancient times (which to us, who live in the present times, appear the most absurd), their total exemption from the secular jurisdiction, for example, or what in England was called the benefit of clergy, were the natural, or rather the necessary, consequences of this state of things. How dangerous must it have been for the sovereign to attempt to punish a clergyman for any crime whatever, if his order were disposed to protect him, and to represent either the proof as insufficient for convicting so holy a man, or the punishment as too severe to be inflicted upon one whose person had been rendered sacred by religion? The sovereign could, in such circumstances, do no better than leave him to be tried by the ecclesiastical courts, who, for the honour of their own order, were interested to restrain, as much as possible, every member of it from committing enormous crimes, or even from giving occasion to such gross scandal as might disgust the minds of the people.

In the state in which things were, through the greater part of Europe, during the tenth, eleventh, twelfth, and thirteenth centuries, and for some time both before and after that period, the constitution of the church of Rome may be considered as the most formidable combination that ever was formed against the authority and security of civil government, as well as against the liberty, reason, and happiness of mankind, which can flourish only where civil government is able to protect them. In that constitution, the grossest delusions of superstition were supported in such a manner by the private interests of so great a number of people, as put them out of all danger from any assault of human reason; because, though human reason might, perhaps, have been able to unveil, even to the eyes of the common people, some of the delusions of superstition, it could never have dissolved the ties of private interest. Had this constitution been attacked by no other enemies but the feeble efforts of human reason, it must have endured for ever. But that immense and well-built fabric, which all the wisdom and virtue of man could never have shaken, much less have overturned, was, by the natural course of things, first weakened, and afterwards in part destroyed; and is now likely, in the course of a few centuries more, perhaps, to crumble into ruins altogether.

The gradual improvements of arts, manufactures, and commerce, the same causes which destroyed the power of the great barons, destroyed, in the same manner, through the greater part of Europe, the whole temporal manufactures, and commerce, the clergy, like the great barons, found something for which they could exchange their rude produce, and thereby discovered the means of spending their whole revenues upon their own persons, without giving any considerable share of them to other people. Their charity became gradually less extensive, their hospitality less liberal, or less profuse. Their retainers became consequently less numerous, and, by degrees, dwindled away altogether. The clergy, too, like the great barons, wished to get a better rent from their landed estates, in order to spend it, in the same manner, upon the gratification of their own private vanity and folly. But this increase of rent could be got only by granting leases to their tenants, who thereby became, in a great measure, independent of them. The ties of interest, which bound the inferior ranks of people to the clergy, were in this manner gradually broken and dissolved. They were even broken and dissolved sooner than those which bound the same ranks of people to the great barons; because the benefices of the church being, the greater part of them, much smaller than the estates of the great barons, the possessor of each benefice was much sooner able to spend the whole of its revenue upon his own person. During the greater part of the fourteenth and fifteenth centuries, the power of the great barons was, through the greater part of Europe, in full vigour. But the temporal power of the clergy, the absolute command which they had once had over the great body of the people was very much decayed. The power of the church was, by that time, very nearly reduced, through the greater part of Europe, to what arose from their spiritual authority; and even that spiritual authority was much weakened, when it ceased to be supported by the charity and hospitality of the clergy. The inferior ranks of people no longer looked upon that order as they had done before; as the comforters of their distress, and the relievers of their indigence. On the contrary, they were provoked and disgusted by the vanity, luxury, and expense of the richer clergy, who appeared to spend upon their own pleasures what had always before been regarded as the patrimony of the poor.

In this situation of things, the sovereigns in the different states of Europe endeavoured to recover the influence which they had once had in the disposal of the great benefices of the church; by procuring to the deans and chapters of each diocese the restoration of their ancient right of electing the bishop; and to the monks of each abbacy that of electing the abbot. The re-establishing this ancient order was the object of several statutes enacted in England during the course of the fourteenth century, particularly of what is called the statute of provisors; and of the pragmatic sanction, established in France in the fifteenth century. In order to render the election valid, it was necessary that the sovereign should both consent to it before hand, and afterwards approve of the person elected; and though the election was still supposed to be free, he had, however all the indirect means which his situation necessarily afforded him, of influencing the clergy in his own dominions. Other regulations, of a similar tendency, were established in other parts of Europe. But the power of the pope, in the collation of the great benefices of the church, seems, before the reformation, to have been nowhere so effectually and so universally restrained as in France and England. The concordat afterwards, in the sixteenth century, gave to the kings of France the absolute right of presenting to all the great, or what are called the consistorial, benefices of the Gallican church.

Since the establishment of the pragmatic sanction and of the concordat, the clergy of France have in general shewn less respect to the decrees of the papal court, than the clergy of any other catholic country. In all the disputes which their sovereign has had with the pope, they have almost constantly taken part with the former. This independency of the clergy of France upon the court of Rome seems to be principally founded upon the pragmatic sanction and the concordat. In the earlier periods of the monarchy, the clergy of France appear to have been as much devoted to the pope as those of any other country. When Robert, the second prince of the Capetian race, was most unjustly excommunicated by the court of Rome, his own servants, it is said, threw the victuals which came from his table to the dogs, and refused to taste any thing themselves which had been polluted by the contact of a person in his situation. They were taught to do so, it may very safely be presumed, by the clergy of his own dominions.

The claim of collating to the great benefices of the church, a claim in defence of which the court of Rome had frequently shaken, and sometimes overturned, the thrones of some of the greatest sovereigns in Christendom, was in this manner either restrained or modified, or given up altogether, in many different parts of Europe, even before the time of the reformation. As the clergy had now less influence over the people, so the state had more influence over the clergy. The clergy, therefore, had both less power, and less inclination, to disturb the state.

The authority of the church of Rome was in this state of declension, when the disputes which gave birth to the reformation began in Germany, and soon spread themselves through every part of Europe. The new doctrines were everywhere received with a high degree of popular favour. They were propagated with all that enthusiastic zeal which commonly animates the spirit of party, when it attacks established authority. The teachers of those doctrines, though perhaps, in other respects, not more learned than many of the divines who defended the established church, seem in general to have been better acquainted with ecclesiastical history, and with the origin and progress of that system of opinions upon which the authority of the church was established; and they had thereby the advantage in almost every dispute. The austerity of their manners gave them authority with the common people, who contrasted the strict regularity of their conduct with the disorderly lives of the greater part of their own clergy. They possessed, too, in a much higher degree than their adversaries, all the arts of popularity and of gaining proselytes; arts which the lofty and dignified sons of the church had long neglected, as being to them in a great measure useless. The reason of the new doctrines recommended them to some, their novelty to many; the hatred and contempt of the established clergy to a still greater number: but the zealous, passionate, and fanatical, though frequently coarse and rustic eloquence, with which they were almost everywhere inculcated, recommended them to by far the greatest number.

The success of the new doctrines was almost everywhere so great, that the princes, who at that time happened to be on bad terms with the court of Rome, were, by means of them, easily enabled, in their own dominions, to overturn the church, which having lost the respect and veneration of the inferior ranks of people, could make scarce any resistance. The court of Rome had disobliged some of the smaller princes in the northern parts of Germany, whom it had probably considered as too insignificant to be worth the managing. They universally, therefore, established the reformation in their own dominions. The tyranny of Christiern II., and of Troll archbishop of Upsal, enabled Gustavus Vasa to expel them both from Sweden. The pope favoured the tyrant and the archbishop, and Gustavus Vasa found no difficulty in establishing the reformation in Sweden. Christiern II. was afterwards deposed from the throne of Denmark, where his conduct had rendered him as odious as in Sweden. The pope, however, was still disposed to favour him; and Frederic of Holstein, who had mounted the throne in his stead, revenged himself, by following the example of Gustavus Vasa. The magistrates of Berne and Zurich, who had no particular quarrel with the pope, established with great ease the reformation in their respective cantons, where just before some of the clergy had, by an imposture somewhat grosser than ordinary, rendered the whole order both odious and contemptible.
