Ravenna, the seat of the Eastern Exarch, who is generally hostile to Gregory, occasions some of his least saintly letters. He hears that Archbishop John wears his pallium on forbidden occasions, and he reproves John with an air of unquestioned authority.[87] John partly disputes the facts, and partly pleads special privileges of Ravenna, but Gregory finds no trace of such privileges and orders him to conform.[88] Then he hears that John and the fine folk of the court are poking fun at him, and his honest anger overflows[89]: "Thank God the Lombards are between me and the city of Ravenna, or I might have had to show how strict I can be." John dies, and we see that the clergy of Ravenna must submit the names of two candidates to Gregory. He rejects the Exarch's man, and chooses an old fellow-monk and friend, Marinianus. But the new Archbishop is forced to maintain the defence of the supposed privileges of Ravenna, and the dispute seems to reach no conclusion during the life of Gregory.
In the isolated peninsula of Istria, the spirit of independence has gone the length of flat defiance, or schism, because the Papacy has acquiesced in the endorsement by the Eastern bishops of the Three Chapters: three chapters of a certain decree of Justinian. The schism is of long standing, and when Gregory is made bishop he sends a troop of soldiers to the patriarch of Aquileia, commanding that prelate and his chief supporters to appear at Rome forthwith, "according to the orders of the most Christian and most Serene lord of all." The use of the Emperor's name seems to have been, to put it politely, not strictly accurate, for when Bishop Severus appealed to Maurice, the Emperor curtly ordered Gregory to desist. We have another indication of the mediæval aspect of Gregory's ideas when, in the following year, he refused to contribute to the relief-fund for the victims of a great fire at Aquileia. His monies were "not for the enemies of the Church," he said. He went on to weaken the schism by other means, partly by bribes, and when Maurice died in 602 and a friendly Exarch was appointed, he at once urged physical force.[90] "The defence of the soul is more precious in the sight of God than the defence of the body," he enacted. He was legislating for the Middle Ages.
