The dispensed priest was excluded from the exercise of sacred ministry (the emergencies of canons 976 and 986 § 2 being excluded), of discharging the extraordinary ministry of distributing Holy Communion, giving a homily or performing a “directive office” in the pastoral field. He was forbidden from functioning in seminaries, or other institutions of higher studies which depend on ecclesiastical authority. In the case of institutions of higher studies which did not depend on an ecclesiastical authority, he was not to teach any discipline either properly theological or closely connected with it.
Now in the case of institutions of lesser studies which depend on ecclesiastical authority, such as a parish program might involve, he was prevented from directing or teaching, “unless the ordinary, according to his prudent judgement and with scandal removed, should judge to decide otherwise with regard to the role of teaching.”
Part of another rescript provided for this relevant ban and also mentions a typical restriction on residence and liturgical functions:
“5. e) in institutions of lesser studies which depend upon ecclesiastical authority, he cannot discharge a directive function or the office of teaching a properly theological discipline. A dispensed priest is bound by the same law in teaching religion in institutions of this type which do not depend upon ecclesiastical authority. f) by this very fact, a priest dispensed from priestly celibacy and, all the more, one who joined in marriage must not live in places where his previous condition is known, nor can he function anywhere in the service of a lector or acolyte or for the distribution of eucharistic communion.”
But then it continued: “6. The Ordinary of the diocese of the petitioner’s domicile or the place where he is staying, on the basis of his prudent judgment and properly informed conscience, after having heard any interested parties and given consideration to the circumstances, can dispense from some or all of the clauses given above under letters e and f.”
Rescripts for dispensed deacons normally do not mention restrictions on residence or liturgical functions. Finally, remember that laicization as well as penal dismissal sever the bonds of incardination, that is, the legal and spiritual attachment to a diocese or religious institute or personal prelature. It thus falls on the ordinary of the petitioner’s residence to determine, if the rescript gives him that power, whether or not he will dispense from those certain restrictions above.
But when laicization has been imposed or dismissal from the clerical state has been imposed there will probably be greater restrictions. The rescript of dismissal I consulted allowed the ordinary to dispense from the restriction on residence, provided no scandal would arise (and here that’s a judgment call the bishop has to make even though later events might cause second guessing). However, it did not provide for the ordinary to dispense from the prohibitions as in “5. e)” above.
All of that having been said, one would have to consult an individual rescript for details.
But it would be possible, and would seem likely, in MaryAgnes’ case of a dispensed priest teaching Bible Study, that the diocesan bishop in which a properly laicized priest lives has sized up the situation and permitted him to teach. Remember that this man did go through the proper channels and is in the good graces of the Church. We don’t know the circumstances of his laicization and don’t have the right to know them. He does have a right to protect his privacy and to a good reputation.
In the case at hand about the unlaicized priest, the bishop of the diocese in which the man is conducting these functions should be approached.
