Please read the passage before reading the commentary.
The book of Wisdom is not considered part of the Bible by every Christian. The Jewish community Jerusalem did not accept it as biblical because of its language and origin. In the century before the Common Era and the birth of Christ, Greek-speaking pagans tried to take over the land of Judea. The book of Wisdom was originally written in Greek by Jews living in Alexandria Egypt. The Jews of Jerusalem did not believe that God would ever reveal himself through the Greek language.
Because of the Jewish hesitancy at accepting Wisdom, not every Christian church has accepted the book as biblical. Catholics, however, do accept the book as part of the inspired words of Sacred Scripture.
The struggle between wickedness and holiness is seen as the struggle between foolishness and wisdom. The wicked were not “thinking right.” The good were “holding themselves aloof” from the wicked. The wicked would try to prove the good people to be stupid by condemning them to shameful deaths. In the outcome the wisdom of the good is discovered to be true wisdom.
Wickedness blinds people from the truth of God’s word. The wicked err in their thinking. The wicked are not wise and think that they know the hidden counsels of God.
We, however, are wise and believe in the goodness and wisdom of God. We can see in the later conflict of those who plotted to kill Jesus, the same struggle between hate and truth, between wisdom and foolishness, between evil and good. With this passage from the book of Wisdom.
We can also see the wisdom of our Lenten works and penance. What seems stupid and foolish to the world God sees as wise and strong. This is true even for those who see in the book of Wisdom sound teaching even if not part of the inspired word of God.
