Vatican II did a pretty good job of that by itself. Get rid of the liberalism of V2, bring back the Latin mass, and stop building modern design monstrosities for churches.
POPE BENEDICT BEGAN THE REFORM OF THE REFORM OF THE SACRED LITURGY after many so called experts of the Liturgy immediately after the Second Vatican Council shrewdly shifted the focus of the Liturgy to man instead of God. The First Commandment of God is: “You shall worship the Lord your God and Him only shall you serve” (CCC 2084; Ex 20:2-5; Deut 5:6-9). The Vatican’s chief exorcist, Father Gabriele Amorth, in an interview of 2001, said: “The Second Vatican Council asked that some texts be revised. Disobeying this command, they set about re-writing them completely with no thought for the danger of making things worse instead of better. So many rites came off badly from this mania to throw out the old and start from scratch, as if the Church to date had always conned us and as if only now the time had at last come of the great geniuses, the super theologians, the super-biblists and the super-liturgists who know what the right thing is for the Church. This is a lie: the last Council simply asked that the texts be revised, not destroyed.” (http://www.speroforum.com/site/article.asp?id=2879; http://www.vaticans.org/index.php?/archives/61-An-interview-with-the-Vaticans-chief-excorcist,-Father-Gabriele.html).
TO FIGHT IN A BATTLE, IS IT NOT PRUDENT AND NECESSARY TO KNOW NOT ONLY YOUR OWN WEAPONS, TACTICS AND STRATEGY BUT ALSO THE WEAPONS, TACTICS AND STRATEGY OF THE ENEMY? It was recounted to Pope John Paul II that the Vatican’s chief exorcist, Father Gabriele Amorth, “knows too many bishops who do not believe in the Devil”. The Pope replied bluntly: “ANYONE WHO DOES NOT BELIEVE IN THE DEVIL DOES NOT BELIEVE IN THE GOSPEL”. When asked “What do you see as Satan’s greatest success?”, Amorth replied: “The fact that he has managed to convince people that he does not exist. He has almost managed it, even within the Church. We have a clergy and an Episcopate who no longer believe in the Devil , in exorcism, in the exceptional evil the Devil can instill, or even in the power that Jesus bestowed to cast out demons. … And they no longer believe in the Devil. We have entire Episcopates trying to counter exorcism. We have countries completely devoid of exorcists, such as Germany, Austria, Switzerland, Spain and Portugal. This is a shameful shortfall.”; (http://www.speroforum.com/site/article.asp?id=2879; http://www.vaticans.org/index.php?/archives/61-An-interview-with-the-Vaticans-chief-excorcist,-Father-Gabriele.html).
