In his dealings with the Donatists, St. Augustine was at first absolutely tolerant, as he had been with the Manicheans. He thought he could rely upon their good faith, and conquer their prejudices by an honest discussion. "We have no intention," he writes to a Donatist bishop, "of forcing men to enter our communion against their will. I am desirous that the State cease its bitter persecution, but you in turn ought to cease terrorizing us by your band of Circumcelliones. . . . Let us discuss our differences from the standpoint of reason and the sacred Scriptures."[1]
In one of his works, now lost, _Contra partem Donati_, he maintains that it is wrong for the State to force schismatics to come back to the Church.[1] At the most, he was ready to admit the justice of the law of Theodosius, which imposed a fine of ten gold pieces upon those schismatics who had committed open acts of violence. But no man was to be punished by the state for private heretical opinions.[2]
The imperial laws were carried out in some cities of North Africa, because many of St. Augustine's colleagues did not share his views. Many Donatists were brought back to the fold by these vigorous measures. St. Augustine, seeing that in some cases the use of force proved more beneficial than his policy of absolute toleration, changed his views, and formulated his theory of moderate persecution: _temperata severitas_.[1]
Heretics and schismatics, he maintained, were to be regarded as sheep who had gone astray. It is the shepherd's duty to run after them, and bring them back to the fold by using, if occasion require it, the whip and the goad.[1] There is no need of using cruel tortures like the rack, the iron pincers, or sending them to the stake; flogging is sufficient. Besides his mode of punishment is not at all cruel, for it is used by schoolmasters, parents, and even by bishops while presiding as judges in their tribunals.[2]
In his opinion, the severest penalty that ought to be inflicted upon the Donatists is exile for their bishops and priests, and fines for their followers. He strongly denounced the death penalty as contrary to Christian charity.[1]
Both the imperial officers and the Donatists themselves objected to this theory.
