With these kind of statements, one wonders whether Bishop Williamson could subscribe to the solemn profession of faith issued by Pope St. Hormisdas and confirmed by the Fathers of Constantinople IV and Vatican I.
So the fathers of the fourth Council of Constantinople, following the footsteps of their predecessors, published this solemn profession of faith: "The first condition of salvation is to maintain the rule of the true faith. And since that saying of our lord Jesus Christ, You are Peter, and upon this rock I will build my Church, cannot fail of its effect, the words spoken are confirmed by their consequences. For in the Apostolic See the Catholic religion has always been preserved unblemished, and sacred doctrine been held in honor. Since it is our earnest desire to be in no way separated from this faith and doctrine, we hope that we may deserve to remain in that one communion which the Apostolic See preaches, for in it is the whole and true strength of the christian religion." (Pastor Aeternus, 4.2)
One recalls the words of Cardinal Hoyos to Bishop Fellay: "today I am convinced that there are those in your ranks who no longer have the true faith in the authentic Tradition of the Church".
Or the words of Cardinal Hoyos to Bishop Fellay to him and two of the other bishops after their initial meeting:
"I find no heretical doctrines nor schismatic attitudes among you."
So, which is it?
