Juízes 15

Juízes 15:4-5

Let us avoid, then, brothers, let us avoid the pestilential deceits of the insidious foxes [heretics]. Let us avoid the deadly frauds of wicked persons lest, like the foxes which that famous strong man Samson once sent into the Philistines' fields, bearing torches on their tails that burned up everything with their flames, the foxes of perverse teachings in like manner either get hold of the fruits of our fields by deceitful traps or consume them by burning flames. Let us, therefore, as we read, be simple and clever—that is to say, simple as doves and clever as serpents, so that the cleverness of the serpents might protect the simplicity of the doves. — SERMON 41.5
