Peter did not forget that, during the late rebellion, the influence of the Church and that of all the leading ecclesiastics had been against him. This was necessarily the case; for, in a Church constituted as that of Russia then was, the powers and prerogatives of the priests rested, not on reason or right, but on ancient customs. The priests would therefore naturally be opposed to all changes--even improvements--in the usages and institutions of the realm, for fear that the system of reform, if once entered upon, might extend to and interfere with their ancient prerogatives and privileges. An established Church in any country, where, by means of the establishment, the priests or the ministers hold positions which secure to them the possession of wealth or power, is always opposed to every species of change. It hates even the very name of reform. Peter determined to bring the Russian Church more under his own control. Up to that time it had been, in a great measure, independent. The head of it was an ecclesiastic of great power and dignity, called the Patriarch. The jurisdiction of this patriarch extended over all the eastern portion of the Christian world, and his position and power were very similar to those of the Pope of Rome, who reigned over the whole western portion. Indeed, so exalted was the position and dignity of the patriarch, and so great was the veneration in which he was held by the people, that he was, as it were, the spiritual sovereign of the country, just as Peter was the civil and military sovereign; and on certain great religious ceremonies he even took precedence of the Czar himself, and actually received homage from him. At one of the great religious anniversaries, which was always celebrated with great pomp and parade, it was customary for the patriarch to ride through the street on horseback, with the Czar walking before him holding the bridle of the horse. The bridle used, on these occasions was very long, like a pair of reins, and was made of the richest material, and ornamented with golden embroidery. The Czar walked on in advance, with the loop of the bridle lying over his arm. Then came three or four great nobles of the court, who held up the reins behind the Czar, one of them taking hold close to the horse's head, so as to guide and control the movements of the animal. The patriarch, who, as is the custom with priests, was dressed in long robes, which prevented his mounting the horse in the usual manner, sat upon a square flat seat which was placed upon the horse's back by way of saddle, and rode in that manner, with his feet hanging down upon one side. Of course, his hands were at liberty, and with these he held a cross, which he displayed to the people as he rode along, and gave them his benediction.
