It was in 385 that the first instance was given of judicial capital punishment for heresy, and the horror which it excited shows that it was regarded everywhere as a hideous innovation. The Gnostic and Manichæan speculations of Priscillian were looked upon with the peculiar detestation which that group of heresies ever called forth; but when he was tried by the tyrant Maximus, at Trèves, with the use of torture, and was put to death with six of his disciples, while others were banished to a barbarous island beyond Britain, there was a most righteous burst of indignation. Of the two prosecuting bishops, Ithacius and Idacius, one was expelled from the episcopate and the other resigned. The saintly Martin of Tours, who had done all in his power to prevent the atrocity, refused to join in communion with them, or with any who communed with them. If he finally yielded, in order to save the lives of some men for whom he had come to Maximus to beg mercy, and also to prevent the tyrant from persecuting the Priscillianists of Spain (where, like the subsequent Cathari, they were detected by their pallor), yet, in spite of the consoling visit of an angel, he was overcome with grief at what he had done, and he found that he had lost for some time the power to expel devils and heal the sick.[188] If the Church thus still shrank from shedding blood, it had by this time reached the point of using all other means without scruple to enforce conformity. Early in the fifth century we find Chrysostom teaching that heresy must be suppressed, heretics silenced and prevented from ensnaring others, and their conventicles broken up, but that the death-penalty is unlawful. About the same time St. Augustin entreats the Prefect of Africa not to put any Donatists to death because, if he does so, no ecclesiastic can make complaint of them, for they will prefer to suffer death themselves rather than be the cause of it to others. Yet Augustin approved of the imperial laws which banished and fined them and deprived them of their churches and of testamentary power, and he consoled them by telling them that God did not wish them to perish in antagonism to Catholic unity. To constrain any one from evil to good, he argued, was not oppression, but charity; and when the unlucky schismatics urged that no one ought to be coerced in his faith, he freely admitted it as a general principle, but added that sin and infidelity must be punished.[189]
