Whether human virtue is a good habit?

❌ Objection 1 : It would seem that it is not essential to virtue that it should be a good habit. For sin is always taken in a bad sense. But there is a virtue even of sin; according to 1 Cor. 15:56: "The virtue [Douay: 'strength'] of sin is the Law." Therefore virtue is not always a good habit.

❌ Objection 2 : Further, Virtue corresponds to power. But power is not only referred to good, but also to evil: according to Is. 5: "Woe to you that are mighty to drink wine, and stout men at drunkenness." Therefore virtue also is referred to good and evil.

❌ Objection 3 : Further, according to the Apostle (2 Cor. 12:9): "Virtue [Douay: 'power'] is made perfect in infirmity." But infirmity is an evil. Therefore virtue is referred not only to good, but also to evil.
