An issue that has arisen with the speculation about the motu proprio is the question of "why does it matter whether the classical rite is more freely available? Does it really matter?"
Fr. Tim Finigan at the Hermeneutic of Continuity has three interesting posts up where he discusses his own vision in response to that question.
I think this question is indeed important. It is equally important for people to understand that focus upon this question, or even the classical liturgy, is not something which is (necessarily) intended as a forced amnesia with regard the Council, nor an immobilism. Rather, the question is very much tied to the question of properly implemented liturgical development.
My own hopes for the motu proprio are not simply tied to my love of the classical liturgy, but they are also tied to my hopes for the reform of the reform.
