I could respond with a lengthy thesis of my own, but I know in my heart, mind and soul what I believe to be the correct situation that exists today within the Roman Catholic Church.
The Church is indeed Roman, being located in Rome, but it is no longer catholic (small c) as liturgy and tenets appear to vary from parish to parish worldwide.
What Vatican II subsequently did, in effect, to the delight of the modernists and secular humanists was to create an entirely new religion based on mankind. I in total honesty believe that our Lord cannot be pleased with the outcome.
I join you in not being altogether pleased with Vatican II. But most of Vatican II was just moving the furniture around and starting to celebrate Mass in the local language. The criticisms are just quibbles.
For 2000 years the Catholic Church has always varied from country to country in non-essentials and surface appearances. In essentials it is unchanged and thank God for it and its lone stand against the extensive depravity of modernity. Most of the martyrs in this new Age of Martyrdom are Roman Catholics though the media insist on the generic term “Christians”.
The essential Mass is the same.
As Scott Hahn has clearly demonstrated in “Consuming the Word: The New Testament and The Eucharist in the Early Church” the “New Testament”is actually not part of a a book. The “New Testament” is the Catholic Mass.
The Mass is the opera, the Bible is just the libretto.
