Oh, wait ...
You're openly protestant. (IIRC).
So ... that makes you at least intellectually honest ... unlike the malfeasant-in-office folks whose misbehaviour prompted the Cardinal to write the subject document.
In terms of public worship, the Church is emphatic that Cardinals not only do not have an exclusive, they have no more authority on most things than the average person in the pew. The liturgy is the public worship of the Church, and it is the duty of the ministers, be they Cardinals or simple priests, to do what the Church says is to be done when performing a particular liturgical acts (like saying Mass). Those who depart from what is given through the Church are by their actions claiming an authority to act for the body in a public way that they do not possess.
You're right.
Bugnini was only an Archbishop when he concocted the Novus Ordo.
