With the recent publication of the Doctrinal Statement of Bishop Fellay, sent to Cardinal Levada on April 15, 2012, several observations have been made but there is something that looks like it is going unnoticed: that is the reference Bishop Fellay makes to the profession of faith of 1989. Indeed, he cites in a note, on paragraph 2 of its statement, as a document that would be the way to accept the teachings of the Magisterium of the Church. Here is a passage of that profession of faith: "I adhere with a religious obedience of will and faith to doctrines that, either the Roman Pontiff or the college of bishops, speak when they exercise the authentic magisterium, even if they don't have the intention to proclaim a definitive act. " Note that this profession of faith is preceded by an introductory text that explains the meaning to be given to such a profession. However, this introduction reads: "It seemed essential to prepare adapted texts, in order to make them updated with regard to your style and your content and put in accordance with the teachings of Vatican II and the documents from the same." [ 2]
And now let us hear Archbishop Lefebvre, with his piercing eyes, giving us a proper appreciation of this document by Cardinal Ratzinger:
"The mistakes of the Council and its reforms remain the official norm consecrated by the profession of faith of Cardinal Ratzinger in March 1989" (Mgr Lefebvre, Itinéraire spirituel, p. 10-11) 
"The new profession of faith which was written by Cardinal Ratzinger contains explicit acceptance of the Council and its consequences. It was the Council and its aftermath that destroyed the Holy Mass, which destroyed our Faith, destroyed the Catechisms and the kingdom of Our Lord Jesus Christ in civil societies. How can we accept it? (...) It is necessary to keep the Catholic Faith, protect it by all means "(Mgr Lefebvre, Paris, le 23 septembre 1979) 
"This is to put us in a contradiction, because while Rome gives the Fraternity of St. Peter, for example, or the Abbey of Barroux and other groups permission to celebrate the Traditional Mass, at the same time they call the new priests to sign a profession of faith in which you must admit the spirit of the Council. It is a contradiction: the spirit of the Council is expressed in the new mass. How do you want to keep the Traditional Mass accepting the spirit that destroys this very same traditional Mass? You put yourself in a complete contradiction. One day, little by little, will be required of those to whom was granted the Mass of St. Pius V, the Mass of all time, it will be required that they also accept the new mass. And it will be said that it is simply that they conform to what they signed, for they have signed because they accept the spirit of the Council and the reforms of the Council. You can not put yourself in such a contradiction, in an aberrant illogic. It's an uncomfortable situation entirely. That's the difficult of these groups who signed it and who currently find themselves in a kind of deadlock. "(Homily, Friedrichshafen, April 29, 1990, quoted in La messe of toujours, p. 428)
What I like especially is to underline the extent to which Bishop Fellay came to cave in order to achieve its objective: the regularilization of Society of St. Pius X
With or without agreement with Rome, the evil is already at the head of Bishop Fellay. And his position is increasingly contaminating the minds of those who trust him.
Our vows that everyone open their eyes, do not be fooled and join those who resist him in the face (cf. Gal. 2, 11-14): ut fideles inveniantur.
 J’adhère aussi avec une obéissance religieuse de la volonté et de la foi aux doctrines que, soit le pontife Romain, soit le collège des évêques, prononcent quand ils exercent le magistère authentique, même s’ils n’ont pas l’intention de les proclamer dans un acte définitif.
 Il est apparu donc indispensable de préparer des textes adaptés pour les mettre à jour en ce qui concerne leur style et leur contenu et les mettre plus en phase avec les enseignements de Vatican II et des documents qui en étaient issus.
 Les erreurs du Concile et ses réformes demeurent la norme officielle consacrée par la profession de foi du Cardinal Ratzinger de mars 1989.
 La nouvelle profession de foi qui a été rédigée par le cardinal Ratzinger contient explicitement l’acceptation du Concile et de ses conséquences. C’est le Concile et ses conséquences qui ont détruit la Sainte Messe, qui ont détruit notre Foi, qui ont détruit les catéchismes et le règne de Notre Seigneur Jésus-Christ dans les Sociétés civiles. Comment pouvons-nous l’accepter ! […] Il nous faut garder la Foi catholique, la protéger par tous les moyens.
