I don’t see why this is such a difficult issue for anyone. SP is very clear. Any secular priest can celebrate the Extraordinary Form without asking for permission.
Priests who belong to religioius orders must get permission from their superiors, if the statutes of their order requires such permission. Otherwise, they too can celebrate the EF. Such was the case with the Franciscans. The statutes do require that any friar who is a priest must receive permission from the Major Superior to celebrate any sacrament. The statutes do not say EF or OF, because they were written before SP. The friars had to ask their Major Superior for permission. The permission is granted on an as needed basis. That’s their right and that of any religious community that has such statutes, according to SP.
The only issue that I can see would be if a priest is assigned to a parish, for the sake of logistics, it makes sense that he ask the pastor for a time slot to celebrate the EF. But that’s not the same as asking for permission to celebrate the EF.
SP has some weaknesses in the way that it is written, because it does not address every specific situation that can arise, such as whether or not one can have a parish where all the masses are EF. I’m assuming that these details will be worked out in time. A Motu Proprio is not intended to answer every detail, but to make a statement in broad terms and then work out the details as you go along.
In charity, we have to be careful not to impose the EF on an entire parish or to deny a parish that wants an EF mass and has someone who is willing to celebrate it. Both are extremes that are unjust.
All things regarding the spiritual welfare of people must be governed by charity. I know that in my community the decision was that the EF would not become the official form for community masses. However, any friar who asks for permission to celebrate or attend is granted that permission provided that the brothers in the community vote on it and the majority agree that it would be a good thing.
The logic here is that in a religious community you have to be careful of two things: 1) observe the statutes of the community unless they are changed by the proper ecclesial authority and the MP did not change the statutes of any religious community or demand that they do so; and 2) you must preserve the unity of the religious community If the community is governed by a Major Superior who must first consult with the community chapter, then that’s the proper way to go. Once he has the approval of the Chapter, the Major Superior is free to grant whatever permissions are authorized to him.
The only place where I can see that one woud have to get permission would be in a parish that is run by religious. The bishop cannot demand that they go over the statutes of their community or forbid that they follow them. This is already built into the contract when a religious community and a bishop agree to work together, such as giving them the administration of a parish.
Other than that, these rules do not apply to secular priests. All they have to do is get a time slot from their pastor, not permission to celebrate the EF. It would be unkind of a pastor to deny the priest a time slot, even if he just adds a mass at the end of the morning on Sunday or a second vigil mass on Saturday. If there are no takers for the mass, that’s no one’s fault and another story altogether. But I imagine that at first, even if it is just out of curiosity, there will be people who want to attend. That’s just my guess.
Another possible problem would be where the priest celebrates two masses in the OF. Usually, you need special permission to celebrate a third mass in either form. Two masses in one day is the usual limit. In large parishes with a small number of priests, it is very common to celebrate two masses in one day. Again, the issue is logistics, not whether the secular priest can celebrate the EF without permission. Of course he can, as long as he does not violate Church law by have three masses without the proper permission, in one day.
This issue witht the EF is now becoming childish. It has been authorized. It’s time that people get over it and follow the rules. If you can do it, go for it. If you can’t, then you can’t. Accept it.
