No one prior to Luther attempted to reduce the Christian Canon, once it was settled in Carthage in early 5 c. The fact that the deuterocanon was not formally recognized until Trent is equally true for any other book, Genesis to Apocalypse. Show me a Christian Bible prior to Trent that did not contain the Deuterocanon, or stop insinuating anything was added by Trent. The lies and half-truths spread by Protestants about the history of the Church are in themselves enough to condemn their entire enterprise to Hell, and you have been corrected enough times to know better.
The Church does not teach that "we receive grace by works". We teach what the scripture say, that we are judged by our works and that we are commanded to do works of charity. We don't disagree that the works are outcome of faith and are enabled by grace.
Likewise, the Church does not teach anything contrary to the fact that "scripture [is a] verification of their ideas". That is not the error of Luther's. I told you very specifically what is: the notion that the subset of the scripture that he likes is sufficient and can be understood outside of the entire Tradition, written and unwritten.
Regarding grace, I explained what is the error: that grace does not regenerate constantly and often gradually in one's lifetime. When pressed to the corner, Protestants usually find a formilation that is vague enough to dance away from Luther's dungheap. That is good that they feel compelled to obfuscate; but the dungheap theory of man is still an error.
I didn't say someone tried to reduce the Canon. I said there were disputes on it.

No, I'm simply correcting the historical distortions that comes from the other side. An excellent article I would refer people to is A Brief Introduction to the Canon and Ancient Versions of Scripture by Michael Marlowe. I would especially call attention to the excellent graph here showing the disputed books of the New Testament. I would also call the readers attention to the following article on the Apocrapha
