Discretion But..

Letter 1,82 - to Hilary, notary of Africa. August 591.

"Felicissimus and Vincent, deacons of the church of Lamigenum, presenting a petition that can be seen below, suggested that they had suffered a serious injustice at the hands of Argentius, bishop of the same city. In return for bribes, they said, Donastists had been put above them in their churches, and they recalled that among other wrongdoings, the bishop had committed another, serious crime, which it would be wrong to mention.
For the reason we thought that with the letter bearing this instruction, we should enjoin your Experience to commit the aforesaid bishop to a suitable pledge without delay.
Through your initiative a council should be formed according to the local custom and, with a thorough investigation, all things should be looked into, in line with the text of the petition presented, according to canon law and before both parties Whatever is decided by their judgement should be carried out in every detail, with you seeing it through."
