Yes, these are some of my same conclusions regarding this. I also found these remarks in the Letter to the Bishops noteworthy:
But I am nonetheless saddened that the instrumental use of Missale Romanum of 1962 is often characterized by a rejection not only of the liturgical reform, but of the Vatican Council II itself, claiming, with unfounded and unsustainable assertions, that it betrayed the Tradition and the “true Church”.
The path of the Church must be seen within the dynamic of Tradition “which originates from the Apostles and progresses in the Church with the assistance of the Holy Spirit” (DV 8). A recent stage of this dynamic was constituted by Vatican Council II where the Catholic episcopate came together to listen and to discern the path for the Church indicated by the Holy Spirit.
To doubt the Council is to doubt the intentions of those very Fathers who exercised their collegial power in a solemn manner cuм Petro et sub Petro in an ecuмenical council,[14] and, in the final analysis, to doubt the Holy Spirit himself who guides the Church.
See, this last statement is not formally incorrect. To claim that these people are the legitimate hierarchy and at the same time are destroying Tradition and the Church, that is in fact to deny that the Holy Spirit guides the Church.
There's only one logical answer: We do not doubt that the Holy Spirit guides the Church. We doubt whether you ARE the Church.
