"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."
-- Benedict XVI
