14 To these also it was not sufficient that they had withdrawn from the Gospel, that they had taken away from the lapsed the hope of satisfaction and repentance, that they had taken away those involved in frauds or stained with adulteries, or polluted with the deadly contagion of sacrifices, lest they should entreat God, or make confession of their crimes in the Church, from all feeling and fruit of repentance; that they had set up outside for themselves— outside the Church, and opposed to the Church, a conventicle of their abandoned faction, when there had flowed together a band of creatures with evil consciences, and unwilling to entreat and to satisfy God.
After such things as these, moreover, they still dare— a false bishop having been appointed for them by, heretics— to set sail and to bear letters from schismatic and profane persons to the throne of Peter, and to the chief church whence priestly unity takes its source; and not to consider that these were the Romans whose faith was praised in the preaching of the apostle, to whom faithlessness could have no access. But what was the reason of their coming and announcing the making of the pseudo-bishop in opposition to the bishops?
For either they are pleased with what they have done, and persist in their wickedness; or, if they are displeased and retreat, they know whither they may return. For, as it has been decreed by all of us — and is equally fair and just— that the case of every one should be heard there where the crime has been committed; and a portion of the flock has been assigned to each individual pastor, which he is to rule and govern, having to give account of his doing to the Lord; it certainly behooves those over whom we are placed not to run about nor to break up the harmonious agreement of the bishops with their crafty and deceitful rashness, but there to plead their cause, where they may be able to have both accusers and witnesses of their crime; unless perchance the authority of the bishops constituted in Africa seems to a few desperate and abandoned men to be too little, who have already judged concerning them, and have lately condemned, by the gravity of their judgment, their conscience bound in many bonds of sins.
Already their case has been examined, already sentence concerning them has been pronounced; nor is it fitting for the dignity of priests to be blamed for the levity of a changeable and inconstant mind, when the Lord teaches and says, “Let your communication be, Yea, yea; Nay, nay.”
