If the doctrines contained therein were not in evidence prior to 1992, then that would be a reasonable statement. There was dispute regarding the Biblical canon right up to the Council of Trent in the 16th century. Under dispute was the so-called Deuterocanon or Apocrypha. The Reformation rejected them as being inspired scripture and therefore part of the canon, however the Apocrypha continued to be included as good for edification but not for doctrine. That language is historic, going back to very early Christianity. It paraphrases whom?
There was no dispute in the Catholic Church. The canon was reaffirmed by Trent only because parts of it were disputed by Protestants.
In the same way, the number of Sacraments (seven) was reaffirmed by Trent. The list of seven was not invented by Trent.
This is a VERY common blunder made by anti-Catholic writers who know no history, but ransack reference books. They often do this: misidentifying some re-statement of a dogma as the moment when the dogma was “INVENTED.”
I have been seeing examples of this same blunder, over and over, for decades. Most anti-Catholic screeds have examples of it.
