What, then, will they have the law to be? They will not call it evil, but just; distinguishing what is good from what is just. But the Lord, when He enjoins us to dread evil, does not exchange one evil for another, but abolishes what is opposite by its opposite. Now evil is the opposite of good, as what is just is of what is unjust. If, then, that absence of fear, which the fear of the Lord produces, is called the beginning of what is good,[1] fear is a good thing. And the fear which proceeds from the law is not only just, but good, as it takes away evil. But introducing absence of fear by means of fear, it does not produce apathy by means of mental perturbation, but moderation of feeling by discipline. When, then, we hear, "Honour the Lord, and be strong: but fear not another besides Him,"[2] we understand it to be meant fearing to sin, and following the commandments given by God, which is the honour that cometh from God. For the fear of God is Δεός [in Greek]. But if fear is perturbation of mind, as some will have it that fear is perturbation of mind, yet all fear is not perturbation. Superstition is indeed perturbation of mind; being the fear of demons, that produce and are subject to the excitement of passion. On the other hand, consequently, the fear of God, who is not subject to perturbation, is free of perturbation. For it is not God, but falling away from God, that the man is terrified for. And he who fears this—that is, falling into evils—fears and dreads those evils. And he who fears a fall, wishes himself to be free of corruption and perturbation. "The wise man, fearing, avoids evil: but the foolish, trusting, mixes himself with it," says the Scripture; and again it says, "In the fear of the Lord is the hope of strength."[3]
