Summorum Pontificum released the Tridentine or Extraordinary Form so that ANY secular priest who belongs to a diocese can celebrate it. If a priest is a diocesan priest, then he is a secular priest. He does not need the permission of the bishop to celebrate the EF. But he must comply with any requirements that his bishop may have for the celebration. For example, if the bishop says that there must be a certain number of people, the priest must comply with that. That is not part of the Motu Propio… That is a diocesan decision. If he has to bump a regular mass from the schedule, he must check that out with the chancery. Mass schedules are usually under the jurisdiction of the local pastor. But the faithful can complain to the chancery if they are bumped, for the EF, precisely because Pope Benedict left that caveat in when he officially named it “extraordinary”. A principle of law is that whatever is extraordinary cannot replace the ordinary unless there is just cause. If you bump 500 people to put in a mass for 100 people, you have a problem and the bishop may not be too happy about it.
Another valid concern that does arise is the number of masses that a priest may say in one day. Normally, the priest should celebrate only one mass. Given the shortage, many priests celebrate two. Three requires permission of the bishop or the major superior, if the priest is a consecrated religious. If the priest is going to add a mass to the parish schedule, he has to ensure that the celebrant does not go over the allowed number of masses that he can celebrate in one day. He has to give preference to that which is ordinary, in this case the OF.
Once the hurdles of schedules and permissions are clear, the next hurdle is the most difficult. Summorum Pontificum gave secular priests permission to celebrate the EF, with specific directives, but it does not mandate it. A priest does not have to accept the request, even if 1,000 people show up at his front door. The law would dictate that he not be looked at as a bad guy because he does not want to celebrate the EF. It is his right to decline the invitation to do so. We’re not talking here about what is or is not more or less spiritual. That gets very subjective. We’re talking here about what is the right of the priest. Only a priest who is a member of a religious order can be mandated to celebrate either form. This is what Summorum Pontificum is referring to when it says “according to common law.”
If the priests in your parish belong to a religious or secular institute, they work in the diocese under a contract. They are not part of the diocese. You are, but they are not. What the bishop can demand of them depends on the contract between the diocese and the community. Regardless of what the bishop may want, once the contract is signed and the religious community is established in the diocese, the contract binds the bishop in perpetuity. He cannot change it unilaterally. That is called suppression. No bishop may suppress a religious once the authority has been granted and the conditions have been agreed upon. There has to be a mutual agreement between the bishop and the religious superior. There is rarely a religious superior who will deny permission to celebrate the EF, especially for the laity. But good manners require that the superior be consulted, even if we know that he’s going to give permission.
I don’t know if your parish priest is a religious, a society priest or a diocesan priest. If he is a diocesan priest, he can celebrate the mass, provided that he clear the hurdles that I mentioned above. If the celebration of the EF disturbs the routine and life of the parish, then he is going to face some difficulties.
Some pastors and religious superiors do allow a priest to come from another place to celebrate mass for a special population. This happens a lot when you have people of another language group or another rite. There is a regular visiting priest who comes every Sunday at a certain time for that population. This may be another avenue that you can pursue. Nevertheless, you have to make sure that you have the numbers before you make that request and you have the money to pay for this service. This may mean paying the priest a stipend and paying a little for AC/heating and so forth. It’s usually very little, just enough to cover the expense.
I would not use the argument of better theology at the EF. The fact is that the Holy Father himself does not believe this. This is an argument made by many people, but not supported by either the Holy Father or by the Vatican Curia. While everyone agrees that the EF is very rich, there is a general agreement that the poor theology of the OF is not because of the form, but because of the incorrect way in which the form is celebrated. This has validity. If you watch the EF on EWTN, at the National Shrine, at certain religious houses, certain parishes or even the Vatican, it is done in a manner that is theologically sound and faithful to the on-going theology of the mass. The richness of the EF is in its externals, not in the essential. The essential is not different between the two forms when done correctly.
The bishop does have control over the masses celebrated in his parishes. Summorum Pontificum gives secular priests permission to celebrat the EF without having to ask for permission. It does not give them permission to change diocesan or parish practices. Canon law must be followed. The bishop as the pastor of his diocese.
If you have enough people who want the EF and no priest in the parish can celebrate it or will celebrate it, you may want to ask the pastor if you can scout around for a priest to come over and do so. But keep in mind the rules. I hope this helps.
