This being the state of the case, no method of pacification was left but written controversy. Augustin shewed himself tireless at it. It was chiefly in these letters and treatises against the Donatists that he was not afraid to repeat himself. He knew that he was dealing with the deaf, and with the deaf who did not want to hear: he was obliged to raise his voice. With admirable self-denial he reiterated the same arguments a hundred times over, a hundred times took up the history of the quarrel from the beginning, spreading such a light over the quibbles and refinings of his contradictors, that it should have brought conviction to the bluntest minds. "No," he repeated, "Cæcilianus was not a _traditor_, nor Felix of Abthugni either who consecrated him bishop. The documents are there to prove this. And even supposing they were, can the fault of a single man be charged to the whole Church?... Then why do you baptize the Catholics under the pretence that their priests are _traditors_ and as such unworthy to administer the Sacraments? It is the sacrifice of Jesus Christ and not the virtue of the priest which renders baptism efficacious. If it were otherwise, what was the good of the Redemption? It is the fact that by the voluntary death of Christ, all men have been called to salvation. Salvation is not the privilege of Africans only. Being Catholic, the Church should take in the whole world...." In the long run, these continual repetitions end by seeming wearisome to modern readers: for us there arises out of all these discussions a dense and intolerable boredom. But let us remember that all this was singularly living for Augustin's cotemporaries, that these thankless developments were read with passion. And then, too, it was a question of the unity of the Church which involved, as we cannot too often repeat, the interest of the Empire and civilization. Against so persuasive a power the Donatists opposed a conspiracy of silence. Their bishops forbade the people to read what Augustin wrote. They did more--they concealed their own libels so that it was impossible to reply to them. But Augustin used all his skill to unearth them. He refuted them, and had his refutations recopied and posted on the walls of the basilicas. The copies circulated through the province and the whole Roman world. This would have had an excellent result if the quarrel had been entirely over questions of theory. But immense property interests came into it, and rancours and terrible hates. Augustin was forced to pass from verbal polemics to direct action--defensive action, at first, and then attack.
