In the four last centuries of the Greek emperors, their friendly or hostile aspect towards the pope and the Latins may be observed as the thermometer of their prosperity or distress; as the scale of the rise and fall of the Barbarian dynasties. When the Turks of the house of Seljuk pervaded Asia, and threatened Constantinople, we have seen, at the council of Placentia, the suppliant ambassadors of Alexius imploring the protection of the common father of the Christians. No sooner had the arms of the French pilgrims removed the sultan from Nice to Iconium, than the Greek princes resumed, or avowed, their genuine hatred and contempt for the schismatics of the West, which precipitated the first downfall of their empire. The date of the Mogul invasion is marked in the soft and charitable language of John Vataces. After the recovery of Constantinople, the throne of the first PalÊologus was encompassed by foreign and domestic enemies; as long as the sword of Charles was suspended over his head, he basely courted the favor of the Roman pontiff; and sacrificed to the present danger his faith, his virtue, and the affection of his subjects. On the decease of Michael, the prince and people asserted the independence of their church, and the purity of their creed: the elder Andronicus neither feared nor loved the Latins; in his last distress, pride was the safeguard of superstition; nor could he decently retract in his age the firm and orthodox declarations of his youth. His grandson, the younger Andronicus, was less a slave in his temper and situation; and the conquest of Bithynia by the Turks admonished him to seek a temporal and spiritual alliance with the Western princes. After a separation and silence of fifty years, a secret agent, the monk Barlaam, was despatched to Pope Benedict the Twelfth; and his artful instructions appear to have been drawn by the master-hand of the great domestic. [1] "Most holy father," was he commissioned to say, "the emperor is not less desirous than yourself of a union between the two churches: but in this delicate transaction, he is obliged to respect his own dignity and the prejudices of his subjects. The ways of union are twofold; force and persuasion. Of force, the inefficacy has been already tried; since the Latins have subdued the empire, without subduing the minds, of the Greeks. The method of persuasion, though slow, is sure and permanent. A deputation of thirty or forty of our doctors would probably agree with those of the Vatican, in the love of truth and the unity of belief; but on their return, what would be the use, the recompense, of such an agreement? the scorn of their brethren, and the reproaches of a blind and obstinate nation. Yet that nation is accustomed to reverence the general councils, which have fixed the articles of our faith; and if they reprobate the decrees of Lyons, it is because the Eastern churches were neither heard nor represented in that arbitrary meeting.
