whatever you are, no matter your trad designation, hoard all your pre-vatican II resources. All the books, everything. I fear that the novus ordo may attempt to edit the church's deposit into something else right out of the stalinist school of falsification. You can only prove error if you have the past in hand, in those texts or even digital copies. You can prove error by saying "tolle, lege" but only if the editions are valid.
