This letter of Cyprian is a response to the letter sent by the presbyters of Rome to Carthage (probably mainly to the clergy) after the death of Bishop Fabian of Rome, in which they condemned the escape of Cyprian and presented the ideal of the clergy that remain with their flock during the persecutions (Letter 8 in the epistolary of Cyprian). Cyprian refers to his decision announced in Letters 15 [1084], 16 [1085], and 17 [1086].
The expression of the “vigour of the priesthood” (sacerdotii vigor) used here is unclear, it may refer either to the rashness of the action of the presbyters and deacons of Carthage, usurping the right to reconcile the penitents, or to the firm countermeasures taken by Cyprian.
