Well, it's not ONLY non-Catholics you reference here, Metmom.
Without conducting "careful" research as to exactly when the term "Catholic Christians" came into vogue...but let's say it 'twas in the late 4th century... THEN we'd be talking about 1,150 years or so of "Catholics" who also didn't uphold the Apocrypha as "official" canonized "Scripture"...who then contemporary Catholics likewise need to condemn.
I stand corrected.
