Augustin was not a man to keep quiet, nor yet to spend his strength in small local quarrels. He saw big; he did not imprison himself within the limits of his diocese. He knew that Numidia and a good part of Africa were in the hands of the Donatists; that they had a rival primate to the Catholic primate at Carthage; that they had even sent a Pope of their community to Rome. In a word, they were in the majority. Everywhere a dissenting Church rose above the orthodox Church, when it did not succeed in stifling it altogether. At all costs the progress of this sect must be stopped. In Augustin's eyes there was no more urgent work. For him and his flock it was a question of insuring their lives, since they were attacked even in their fields and houses. From the moment he first came to Hippo, as a simple priest, he had thrown himself intrepidly into this struggle. He never ceased till Donatism was conquered and trampled underfoot. To establish peace and Catholic unity everywhere was the great labour of his episcopate. Who, then, were these terrible Donatists whom we have been continually striking against since the beginning of this history? It would soon be a century since they had been disturbing and desolating Africa. Just after the great persecution of Diocletian, the sect was born, and it increased with amazing rapidity. During this persecution, evidence had not been wanting of the moral slackness in the African Church. A large number of lay people apostatized, and a good number of bishops and priests handed over to the pagan authorities, besides the devotional objects, the Scriptures and the muniments of their communities. In Numidia, and especially at Constantine, scandalous scenes took place. The cowardice of the clergy was lamentable. Public opinion branded with the names of _traditors_, or traitors, those who had weakened and given over the sacred books to the pagans. The danger once over, the Numidians, whose behaviour had been so little brilliant, determined to redeem themselves by audacity, and to prove with superb impudence that they had been braver than the others. So they set themselves to shout _traditor_ against whoever displeased them, and particularly against those of Carthage and the Proconsulate. At bottom it was the old rivalry between the two Africas, East and West.
