Cyril of Alexandria : The wise and eloquent people among the pagans are full of admiration for a well-turned phrase. One of their main preoccupations is with elegance of expression. They are filled with the greatest enthusiasm for good style and take great pride in verbal dexterity. The base material of their poets is merely lies fashioned in rhythms and meters for grace and harmony, but for truth they have little if any regard. I would say that they are sick from the lack of any true or proper notion of the nature and reality of God.… And God said of them through the voice of Isaiah, "Know that their hearts are dust and that they have erred." … As for the inventors of impure heresies, those profaners and apostates who have opened their mouths against the divine glory, "those who have uttered perverted things," we could accuse them of having slipped in their madness as low as the foolish pagans; perhaps they have slipped even lower, for it would have been better never to have known the way of sacred truth than once to have known it, to have turned away from the sacred commandment that was handed on to them. — ON THE UNITY OF CHRIST Jerome : Whatever is said about idols can also be applied to the leaders of heresies, who create images of their doctrines and lies with cunning hearts and worship things that they know are made by themselves. And their own error is not enough for them, unless they deceive even the simplest of their followers with their worship. Those who think that gain is godliness and devour the homes of widows (I Tim. VI), taking advantage of the ignorance of the common people, in this way, with dialectic art, as if with an axe and drill, they shape their own god, and they forge with a hammer, and they gild with the elegance of rhetorical language: of whom their god is their belly, and their glory is in their shame (Philipp. III). — Commentary on Isaiah
