12. Which are done by them in secret. This shews the advantage of reproving the ungodly. If they do but escape the eyes of men, there is no crime, however shocking to be mentioned, which they will not perpetrate. To use a common proverb, “Night has no shame.” What is the reason of this? Sunk in the darkness of ignorance, they neither see their own baseness, nor think that it is seen by God and by angels. But let the torch of God’s word be brought forward, and their eyes are opened. Then they begin to blush and be ashamed. By their advices and reproofs the saints enlighten blind unbelievers, and drag forth from their concealment to the light of day those who were sunk in ignorance.
When unbelievers keep the doors of their houses shut, and withdraw from the view of men, it is a shame even to speak of the baseness and wickedness with which they rush into all manner of licentiousness. Would they thus lay aside all shame, and give loose reins to their passions, if darkness did not give them courage, — if they did not entertain the hope that what is hidden will pass unpunished? But do you, by reproving them, bring forward the light, that they may be ashamed of their own baseness. Such shame, arising from an acknowledgment of baseness, is the first step to repentance.
“If there come in one that believeth not, or one unlearned, he is convinced of all, he is judged of all; and thus are the secrets of his heart made manifest; and so, falling down on his face, he worships God” (1 Corinthians 14:24.)
It may be thought that the word is used here in an unusual acceptation. Erasmus, by substituting another word for reprove, has destroyed the whole meaning; for Paul’s object is to shew that it will not be without advantage if the works of unbelievers are reproved.
