4.  Next comes Apollinarius, who is no less a cause of sorrow to the Churches.  With his facility of writing, and a tongue ready to argue on any subject, he has filled the world with his works, in disregard of the advice of him who said, “Beware of making many books.” Ecc. xii. 12, LXX.  cf. Ep. ccxliv. p. 286.  In their multitude there are certainly many errors.  How is it possible to avoid sin in a multitude of words? cf. Prov. x. 19.  And the theological works of Apollinarius are founded on Scriptural proof, but are based on a human origin.  He has written about the resurrection, from a mythical, or rather Jewish, point of view; urging that we shall return again to the worship of the Law, be circumcised, keep the Sabbath, abstain from meats, offer sacrifices to God, worship in the Temple at Jerusalem, and be altogether turned from Christians into Jews.  What could be more ridiculous?  Or, rather, what could be more contrary to the doctrines of the Gospel?  Then, further, he has made such confusion among the brethren about the incarnation, that few of his readers preserve the old mark of true religion; but the more part, in their eagerness for novelty, have been diverted into investigations and quarrelsome discussions of his unprofitable treatises.
