Chapter 2.—The Fear of God is Man’s True Wisdom.

The true wisdom of man is piety. You find this in the book of holy Job. For we read there what wisdom itself has said to man: “Behold, the fear of the Lord [pietas], that is wisdom.” 1093 If you ask further what is meant in that place by pietas, the Greek calls it more definitely θεοσέβεια, that is, the worship of God. The Greeks sometimes call piety εὐσέβεια, which signifies right worship, though this, of course, refers specially to the worship of God. But when we are defining p. 238 in what man’s true wisdom consists, the most convenient word to use is that which distinctly expresses the fear of God. And can you, who are anxious that I should treat of great matters in few words, wish for a briefer form of expression? Or perhaps you are anxious that this expression should itself be briefly explained, and that I should unfold in a short discourse the proper mode of worshipping God?
