Pope Emeritus Benedict XVI, as Cardinal Ratzinger, places Vatican II in its rightful place and wrote in The Ratzinger Report:
"I am convinced that the damage that we have incurred in these twenty years is due, not to the ‘true’ Council, but to the unleashing within the Church of latent polemical and centrifugal forces; and outside the Church it is due to the confrontation with a cultural revolution in the West: the success of the upper middle class, the new ‘tertiary bourgeoisie’, with its liberal-radical ideology of individualistic, rationalistic and hedonistic stamp. The cardinal exhorts all Catholics who wish to remain such “to return to the authentic texts of the original Vatican II.” The Ratzinger Report, Vittorio Messori, Ignatius, 1985, p 28-31].
“It must be stated that Vatican II is upheld by the same authority as Vatican I and the Council of Trent, namely, the Pope and the College of Bishops in communion with him, and that also with regard to its contents, Vatican II is in strictest continuity with both previous councils and incorporates their texts word for word in decisive points…” (The Ratzinger Report, p 28).
Cardinal Ratzinger expressed the required fidelity to Vatican II as: “to defend the true tradition of the Church today is to defend the Council…And this today of the Church is the documents of Vatican II, without reservations that amputate them and without arbitrariness that distorts them.” (The Ratzinger Report, Ignatius Press, 1985, p 31).
Fr William Most examined ten legitimate changes at Vatican II and found not one was a reverse of doctrine. All gave answers to previously debated points. Fr Most concludes: “It is obvious then that Vatican II did not create a revolution in theology. There are no reversals of teaching at all, and some…are only a little different or stronger than previous teachings, but all are in the same direction.” Catholic Apologetics Today: Answers To Modern Critics, Fr William G Most, TAN, 1986, p 200].
