Sure I can, because it is a knowledge possessed by the Church, which is not expressed in the scripture.
Then it's meaningless.
If it's not in Scripture, it's not infallible. It's merely the opinion of men.
I really don't care much what a bunch of corrupt, immoral, charlatans who claimed some sort of special spiritual insight due to the positions they awarded themselves thought.
The actions and behavior of the Catholic church for the majority of its history shows a dearth of spiritual insight and leading.
They ought to just hang a sign above the door of the Vatican that says *Ichabod*. There is no godliness there.
When they can get their act together and start acting like the Christ they claim to represent, then they'll gain some credibility and might have something worth saying and listening to.
But until they clean house and do it publicly and decisively, they have nothing to say.
