In the Church there is no law or jurisdiction which can impose on a Christian a diminution of his faith. All the faithful can and should resist whatever interferes with their faith, supported by the catechism of their childhood. If they are faced with an order putting their faith in danger of corruption, there is an overriding duty to disobey.
It is because we judge that our faith is endangered by the post-conciliar reforms and tendencies, that we have the duty to disobey and keep the Tradition. Let us add this, that the greatest service we can render to the Church and to the successor of Peter is to reject the reformed and liberal Church. Jesus Christ, Son of God made man, is neither liberal nor reformable. On two occasions I have heard emissaries of the Holy See say to me: “The social Kingdom of Our Lord is no longer possible in our times and we must ultimately accept the plurality of religions.” This is exactly what they have said to me.
Well, I am not of that religion. I do not accept that new religion. It is a liberal, modernist religion which has its worship, its priests, its faith, its catechism, its ecumenical Bible translated jointly by Catholics, Jews, Protestants and Anglicans, all things to all men, pleasing everybody by frequently sacrificing the interpretation of the Magisterium. We do not accept this ecumenical Bible. There is the Bible of God; it is His Word which we have not the right to mix with the words of men.
"So let us be confident, let us not be unprepared, let us not be outflanked, let us be wise, vigilant, fighting against those who are trying to tear the faith out of our souls and morality out of our hearts, so that we may remain Catholics, remain united to the Blessed Virgin Mary, remain united to the Roman Catholic Church, remain faithful children of the Church."- Archbp. Lefebvre 1980
