XIX. 1. or as but an imperfect idea, let us now note how clearly the divine Scriptures explain a thing about which we see the philosophers held so many involved and perplexing ideas. For the Scriptures state that nothing is good but what is virtuous, and declare that virtue is blessed in every circumstance, and that it is never enhanced by either corporal or other external good fortune, nor is it weakened by adversity. No state is so blessed as that wherein one is free from sin, is filled with innocence, and is fully supplied with the grace of God. For it is written: “Blessed is the man that hath not walked in the counsel of the ungodly, and hath not stood in the way of sinners, and hath not sat in the seat of pestilence, but in the law of the Lord was his delight.” Ps. i. 1, 2. And again: “Blessed are the undefiled in the way, who walk in the law of the Lord.” Ps. cxix. 1.
