I am not criticising Pope Paul VI as a person, but I don’t think it is unfair, or uncharitable, or disrepectful to say that he made some mistakes. The Novus Ordo Mass, on the whole was a mistake.
What should have happened, and would surely have been beneficial, are the changes the council visualised and set out in the document. That document was the synthesis and summation of the liturgical movement.
What I object to, is people saying that the Novus Ordo Mass was a direct result of the council, or is faithful to the council. To answer the OP question: in my opinion, the NO was a direct betrayal of the vision of the liturgical movement and council fathers. I know perfectly well it did not HAVE to relate at all to SC, but it surely should have done.
Paul VI signed on the dotted line - that means the document has his authority, and he certainly had the right to promulgate it. It does not mean that it is perfect, or immunises it from criticism, or the fact that it was an unwise decision.
