I was in a similar situation although it was (some) choir members from our TLM who were helping out a pastor at a nearby parish to start a schola to chant Vespers (EF) once a month. The original plan was to have our singers be the "starter" for their schola. Well, several months went by and no singers from their parish ever materialized. We finally told the pastor that we couldn't support his parish indefinitely and eventually stopped going.
I talked this over with my pastor. It’s a real challenge getting some of these guys to take off the training wheels and ride. Also it’s a bit scary, as their formation is so sketchy you worry about the wacky things they might try, even with the best intentions.
IMO a big part of the problem is that younger pastors have not been formed in traditional liturgy, nor even in the use of Latin. It’s all a foreign country to them, which they have visited once or twice as sympathetic tourists. We laity for whom this has been our normal mode of worship for decades sometimes forget the disadvantage of most diocesan priests in this respect. They need just the right blend of encouragement and tough love.
A week ago I sent a tough love e-mail to the pastor I mentioned above, who’s been dragging his feet over getting up to speed. So far no response. It hurts, because my guys really really want to see the TLM flourish, and it kills us to say “no mas” (pun not intended, but what the heck). But I can’t ask lay men to serve at three or even four Masses on a Sunday because another pastor hasn’t been able to get commitments from his own folks. If those commitments are simply not to be had, he should celebrate alone and put the rest in God’s hands. Isn’t that how St. Jean Vianney did it?
If asked, I know just what I want to say to those priests who’re putting off the heavy lifting: “Father, souls are at stake. Every day is a gift — and eternity is forever.”
Happy New Year.
