That the Latins are heretics there is no need of our producing any proof for the present. The very fact that we have entertained so much hatred and aversion against them for so many centuries is a plain proof that we loathe them as heretics, in the same way, that is to say, as we do Arians, or Sabellians, or Spirit denying and Spirit-defying Macedoniacs. . . . Enough was said concerning them by St. Mark of Ephesus in Florence (at the twenty-fifth general assembly), who spoke frankly as follows: We have split ourselves off from the Latins for no other reason than the fact that they are not only schismatics but also heretics.” Wherefore we must not even think of uniting with them.
