All too familiar. Someone announces they reject some or all of the Church's teachings, and then denounces contra opinions as "traditionalists", ossified, knuckle-draggers.

Certainly Q has its defenders. So does the notion that Christ did not rise from the dead.

As a Catholic I understand that the source of the canon, the Church, filters the cacophony of "scholarship" under the guidance of the Holy Spirit, just as it provided the canon itself.

Yes, that is the nature of modern scholarship, where getting published requires asserting 1+1=3. I am not at all "discomfited by it". On the other hand, I am considerably less gullible than some people.
