Use of the 1962 Missale Romanum has been growing since Summorum Pontificum went into effect. And growing steadily.
Here is some good news from Denmark:
Dear Father Z
I have great news from the cold north of Scandinavia. The Saint Charles Borromeo Group have finally brokered a deal with the Bishop of Copenhagen and the parish priest at Jesus Heart Church in Vesterbro(a Borough) every first and third sunday 6.00 pm/ 18.00.
After some unsuccessful results in the initial phase of trying to get a TLM mass at the Church, we went to the Bishop. But it took two months of negotiations. It has to be said that it is not the Parish Priest who celebrates the mass but the secondary priest. The Parish Priest and the Parish Council turned our group away, saying that they could not recognize us as a stable group. Even though our group have existed since 1997 and have been celebrating the TLM once a month in a secluded school chapel.
Note well: There were patient negotiations involved. They overcame resistance with patience and negotiation.
Going to priests and bishops and being nasty or pushy will not get you what you want.
Be careful and prudent.
