Moreover, he directed his attention—as Hormisdas had done before him—to the struggle which was never at rest between the Greek and Roman churches. The Patriarch of Constantinople was determined to assert his own superior claims to the veneration of the faithful. Hormisdas had avowed—but never vindicated—the supremacy of the Pope. But his title of _Papa_ was the result of mere adulation and never of general consent. And the patriarch happened to be at this time the strong-willed John the Faster—an austere and pugnacious man. It was natural therefore that he should claim the title of Universal Bishop, and it was equally natural that Gregory, without demanding anything especial for himself, should resist John. In this controversy—and in those others where his works bear testimony to his literary and political skill—we see Gregory at his best. He is not deficient in satire; occasionally he indulges in playful humor; but he never forgets principle nor flinches from the prosecution of his cause. It cannot be said of him that he proposes to overrule the civil authorities, but he unquestionably tells them some exceedingly plain truths. To the Emperor Maurice he wrote remonstrating against his refusal to allow a soldier to become a monk: “To this by me, the last of His servants and yours, will Christ reply, ‘From a notary I made thee a count of the body-guard; from a count of the body-guard I made thee a Caesar; from a Caesar I made thee an emperor; nay, more, I have made thee also a father of emperors; I have committed My priests into thy hand; and dost thou withdraw thy soldiers from My service?’ Answer thy servant, most pious lord, I pray thee, and say how thou wilt reply to thy Lord in the judgment, when He comes and thus speaks.” In this style he alternately appealed and remonstrated in his dealing with the powers that be. To John the Faster, however, he administered gall and honey—sometimes separately and sometimes mixed together. “Your holy Fraternity,” he says, on one occasion, “has replied to me, as appears from the signature of the letter, that you were ignorant of what I had written about. At which reply I was mightily astonished, pondering with myself in silence, if what you say is true, what can be worse than that such things should be done against God’s servants and he who is over them should be ignorant?” Two monks had in fact been beaten with cudgels for heresy and finally resorted to Rome in defiance of John, where Gregory pardoned and restored them. The Pope continues: “But, if your holiness did know both what subject I wrote about and what had been done, either against John, the Presbyter, or against Athanasius, monk of Isauria and a presbyter, and have written to me, ‘I know not,’ what can I reply to this, since Scripture says, ‘The mouth that lies slays the soul?’ I ask, most holy brother, has all that great abstinence of yours come to this, that you would, by denial, conceal from your brother what you know to have been done?”
