''CLXXVII. Letter to Andreas, Bishop of Samosata.''

The illustrious Aristolaus has sent Magisterianus from Egypt with a letter of Cyril in which he anathematizes Arius, Eunomius, Apollinarius and all who assert Christ&#8217;s Godhead to be passible and maintain the confusion and commixture of the two natures. Hereat we rejoice, although he did withhold his consent from our statement. He requires further subscription to the condemnation which has been passed, and that the doctrine of the holy bishop Nestorius be anathematized. Your holiness well knows that if any one anathematizes, without distinction, the doctrine of that most holy and venerable bishop, it is just the same as though he seemed to anathematize true religion.

We must then if we are compelled anathematize those who call Christ mere man, or who divide our one Lord Jesus Christ into two sons and deny His divinity, etc.
