Licentiousness contends with chastity, righteousness with injustice, arrogance with modesty, and, in general, everything considered contrary with its opposite. By his own example Moses teaches us to stand on the side of virtue, as on the side of a fellow countryman. He teaches us to destroy the adversary who rises against it. For the victory of virtue becomes the ruin and disappearance of idolatry. In the same way, injustice is destroyed by righteousness, and arrogance is slain by modesty. But there is also in us a struggle between those of the same race. We would not have dogmas invented by evil heresies if a structure of erroneous reasonings did not contend against sounder reasonings. If we are weak and unable to strengthen the right side, because evil has prevailed by its devices and the authority of truth has been overthrown, then we must flee away as quickly as possible. The example of Moses proposes this flight toward the better and higher teaching concerning the mysteries. And if it is again necessary to dwell with a foreigner, that is, if we are compelled to turn to pagan philosophy, we may do this only after driving away the evil shepherds. They unlawfully use the well. That is, we must first expose false teachers in their evil use of external learning. Thus we shall live by ourselves, not getting involved in the quarrel and not acting as mediators in it. We shall dwell among those of one mind, whose will agrees with ours, together with our own flock. And all the movements of our soul will follow the guiding Word, like sheep following a shepherd.
