I. The disorderly appointments of bishops which have been made in the province are reprehensible.
Inasmuch as the frequent accounts of those who visited us made mention of certain unlawful practices among you with regard to the ordination of priests, the demands of religion required that we should strive to arrive at the exact state of the case in accordance with that solicitude which by the Divine command we bestow on the whole Church: and so we delegated the charge of this to our brother and fellow priest, Potentius, who was setting out from us: and who, according to what we wrote and addressed to you by him, was to make inquiry as to the facts about the bishops whose election was said to be faulty, and to report everything faithfully to us.
Wherefore, because the same Potentius has most fully disclosed all to our knowledge, and has by his truthful account made clear to us, under what and what manner of governors some of Christ's congregations are placed in certain parts of the province of (Mauritania) Cæsariensis, we have found it necessary to open out the grief wherewith our hearts are vexed for the dangers of the Lord's flocks, by sending this letter also to you beloved: for we are surprised that either the over-bearing conduct of intriguers or the rioting of the people had so much weight with you in a time of disorder, that the chief pastorate and governance of the Church was handed over to the unworthiest persons, and such as were farthest removed from the priestly standard.
This is not to consult but harm the peoples' interests: and not to enforce discipline but to increase differences. For the integrity of the rulers is the safeguard of those who are under them: and where there is complete obedience, there the form of doctrine is sound. But an appointment which has either been made by sedition or seized by intrigue, even though it offend not in morals or in practice, is nevertheless pernicious from the mere example of its beginning: and it is hard for things to be carried to a good issue which were started with a bad beginning.
