But your argument makes no sense. Initially you asserted that, if there is interest in the TLM, a parishoner need only to ask and it will be supplied. Now you are saying that, in order to ask, there need first to be a “stable community.” If people don’t know about the TLM in the first place (which, I hope we can agree that many don’t), then they will never have the opportunity to be exposed to it unless these “stable communities” start appearing out of the ether to request TLMs.
Let me be more specific: a group of people should ask. It is unrealistic to think that a pastor is going to change a schedule of Masses for one person. And you seem to think that if people are exposed to it, they’re going to be enthused. I don’t think they will be. Like At Trent’s poll, I’m sure people would say, “Sure, I’ll go.” Then they’d go, realize it’s in Latin, realize that they cannot hear the priest for significant portions of the Mass, etc. I believe for the most part, they’re going to say, "Oh, well, I guess that was nice…but I like the Mass in my language and I like to be able to hear it."
Let me give you two first-hand accounts of my attempts to request a TLM. Both occurred some time after Summorum Pontificum. The first was at a Catholic University that I won’t name out of charity. It is enough to say that it is highly regarded as “orthodox” within the Catholic world. A large group of students, interested in access to the TLM, compiled a petition to request (in accordance with Summorum Pontificum) for a TLM to be said on campus. The petition received a few hundred signatures. The request was denied twice. After I graduated, I was informed that, after some further argument over the matter, the school had decided to provide a shuttle so that students could attend the TLM in the local city. Now, I honestly do not know, but I read somewhere that institutions and orders were not bound by SP. Perhaps it was Br.JREducation, but I’m not certain.
The second occurred at a much larger Catholic school with similar results (petition denied with several hundred signatures). Both schools offered several Masses on Sunday both in the morning and the afternoon. See above.
