The Church's teaching authority cannot be frozen in the year 1962 - this must be quite clear to the Society. But some of those who put themselves forward as great defenders of the Council also need to be reminded that Vatican II embraces the entire doctrinal history of the Church. Anyone who wishes to be obedient to the Council has to accept the faith professed over the centuries, and cannot sever the roots from which the tree draws its life.
Amy Welborn at her new home, Via Media, comments (emphases mine):
And this is what Benedict is saying. He's asking those of us tempted to want to "sing a new church" into being and to cling to a particular interpretation of Vatican II to think a little bit more deeply and seriously. Yes, the SSPX is going to have to accept what the Council and post-Conciliar Popes have taught about various issues, including ecumenism.
But doesn't that mean the rest of us are obliged to accept Trent?
Like many of her posts, it is wide ranging and thought provoking, so see the whole thing.
