"I celebrated Mass according to the new liturgical directives of 1965, but never according to the definitive ones of 1968, which bear the signature of Monsignor Bugnini. [...] The Faith is the teaching of the Church throughout the centuries, in accordance with the teaching of the Apostles. [...] I give you another definition, that contained in the anti-modernist oath of St. Pius X: the submission of the intellect and will to the Revelation of God, because God is the supreme authority and cannot err. Interviwer: And do you really think that Paul VI and John Paul II substantially changed this fundamental core of the Faith? Mgr. Lefebvre: I think they give another definition of the Faith. For them, Faith is a religious sentiment, an interior, subjective act. [...] The conscience is made to obey Revelation, not for itself. The problem is that for the last popes—speaking in Christian terms— the “subject” comes before the “object.” Whereas for the Tradition of the Church, the exact opposite is true: the object precedes the subject."
