But this was not all. It is possible that in time the citizens, weary of their decadent rulers, might have come to accept without active discontent the rule of a gallant and chivalrous Christian knight such as Baldwin. But the Crusaders, and most of all the Pope, would not be content with this. If they were justified at all in the havoc they had made it was only because the Easterns were heretics and idolaters and schismatics. The Church of Constantinople was "rebellious and odious" to that of Rome. It must be brought to submission. So a century later the case is summed up, "God delivered the city into the hands of the Latins because the Greeks declared that the Holy Ghost proceeded only from the Father, and celebrated the mass with leavened bread." Such was the feeling,--though the expression of it is somewhat of an anachronism,--that animated now the leaders of the hosts, which, sated with their debauchery, began to feel something of an inevitable remorse. But Innocent III. was of too pure a soul to countenance the iniquity that had been committed. Among all the shameless hypocrisies of the time his words of denunciation ring out true. Even the union of the Churches on which he had set his heart seemed to him now to be impossible. "Disappointment, shame, and anxiety weaken us when we ask whether the Greek Church can enter into union with the Apostolic see when that Church had seen among the Latins only the works of darkness." Meanwhile the Venetians set canons in the Church of S. Sophia, and elected Morosini to be patriarch. It was an empty honour. In fifty-seven years a Greek again was seated on the throne of Justinian, and the Liturgy of S. Chrysostom was again sung in S. Sophia; but long before that revolts had made the Latin hold on the East more and more precarious, and the city more and more able to reassert its ancient independence. 4.
