Titus 2:12

12Teaching us that, denying, ungodliness He now lays down the rule for regulating our life well, and how we ought to begin, namely, with renouncing our former life, of which he enumerates two parts, “ungodliness and worldly desires.” Under ungodliness, I include not only superstitions, in which they had gone astray, but irreligious contempt of God, such as reigns in men, till they have been enlightened in the knowledge of the truth. Although they have some profession of religion, yet they never fear and reverence God sincerely and honestly, but, on the contrary, have consciences that are useless, so that nothing is further from their thoughts than that they ought to serve God. (250)

By worldly desires (251) he means all the affections of the flesh; because we look at nothing but the world, till the Lord has drawn us to himself. Meditation on the heavenly life begins with regeneration. Before we have been regenerated, our desires lean towards the world, and rest on the world.

That we may live temperately, and righteously, and piously As he formerly mentioned those three, when he wished to give a comprehensive summary of Christian life, so he now makes it to consist of those three, “piety, righteousness, and temperance.” “Piety” is religion towards God. “Righteousness” has place among men. He who is endowed with both of these lacks nothing for perfect virtue; and, indeed, in the law of God there is absolute perfection, to which nothing whatever can be added. But as the exercises of godliness may be regarded as appendages to the first table, so “temperance,” which Paul mentions in this passage, aims at nothing else than keeping the law, and, as I said before about patience, (252) is added to the former as a seasoning. Nor does the Apostle contradict himself, when at one time he describes patience, and at another time temperance, as the perfection of a holy life; for they are not distinct virtues, since σωφροσύνη (here translated temperance) includes patience under it.

He adds, in this world, (253) because the Lord has appointed the present life for the trial of our faith. Although the fruit of good actions is not yet visible, yet the hope should be sufficient for stimulating us to doing well; and this is what he immediately adds, —
