"The claim of the partisans of progressivism that the future belongs to them is totally unwarranted. It represents only an act of faith supported neither by science, philosophy, history, or revelation. It would be absurd and futile and a betrayal of Her mission for the Church to attempt to adapt Herself to the modern age, to the "future". As Pope John XXIII has said: The Church must give Her imprint to the nations and historical epochs, and not the reverse."
-- Dietrich Von Hildebrand (Trojan Horse in the City of God)
For the Purification of the Church from all Error
Dissipate, we humbly beseech Thee, O Lord Jesus Christ, throughout Thy whole Church every self-willed opinion which tends by subversion of the faith to counteract the truth; that as Thou art acknowledged in heaven and in earth to be the one and only God, so Thy people, gathered from all nations, may with visible communion glorify Thee in the unity of the faith handed down from the beginning, Who livest and reignest with the Father and the Holy Ghost, one God, world without end. Amen
