12 You, Venerable Brethren, We earnestly exhort to embrace with paternal charity erring priests immediately they sincerely repent, and not to refuse to call them again, under your direction, to their priestly duties, when they have been duly proved worthy. But should they, which may God forbid, reject your exhortations and persevere in their contumacy, it will be Our care to see that they are severely dealt with. Study to lead back to the right path the faithful of Christ who are now laboring under a delusion that may be pardoned; and foster in your dioceses those practices of piety, recently or long since approved in numerous documents issued by the Apostolic See, and do this with all the more alacrity now when by the blessing of God priests among you are enabled to exercise their ministry and the faithful to emulate the example of piety of their fathers.
