The Popes Against Modern Errors

In 1789, the French Revolution took place and launched a host of religious, political, and social errors that the Popes for over 160 years wrote and legislated against. Yet most of these errors have today filtered down to the common man... with the result that most people now take for granted many fundamental assumptions that are positively false! But almost from the beginning of these errors, the Popes spoke out as with one voice, inveighing against them.
