In private correspondence, Moretben reminded me of a posting of his which, I realise, has been gnawing away at me for just under a year, and which was the source of an increasing concern: why should anything in the Church change?
I understand the need for aggiornamiento: the Church must always be able to proclaim the Faith in a way in which people of each Age can respond to; a nineteenth century priest reading out an eighteenth century court sermon of Bourdaloue to a bunch of working class men and women is, to say the least, inappropriate.
I understand the need for resourcissement: we can't understand the Tradition unless we constantly seek to understand where it has come from. Pius IX said "La tradizione sono io": "I am Tradition"; and he was completely and utterly wrong.
But (and here's a big but) why does either of these principles mean that, for example, the Easter Vigil has to take place at Midnight, when over the course of 1500 years the sense of the Church had gradually moved the time of the celebration?
These are deep waters, and I am not a confident swimmer: but if the Extraordinary Use is to be recognised again, and the anti-traditionalism of the post-Vatican II era is finally to be challenged; and if the 1965 revision of the Missal is to be ignored; and if the idea of "change by Papal Fiat" has gone away; why has the 1962 Missal been selected as a high water of orthodoxy?
