1618. The Exercise of the Gift of Wisdom.—(a) The external magisterium (i.e., revelation and the teaching Church) conveys the truths of faith to the mind of the believer. (b) The internal Teacher, the Holy Ghost, illuminates the soul with Wisdom, so that it ponders on the first principles of faith and makes the love of them control its judgments, Words, and actions: “You have the unction from the Holy One and know all things” (I John, ii. 20), that is, all that is needed for salvation.
1619. The Beatitude and the Fruits that Correspond to Wisdom.—The Gifts of the Holy Ghost, by supplying for what is imperfect in the habits of virtue (e.g., by protecting faith against dullness of perception, hope against presumption, charity against distaste for divine things), give to these virtues a perfectionment like to that which they will have in the state of beatitude, and to their exercise a corresponding enjoyment. Hence, to the Gifts, which are most excellent habits, correspond those most perfect or most delightful acts of virtue known as Beatitudes and Fruits (see 159 sqq.).
(a) There appears a special correspondence of the seventh beatitude (“Blessed are the peacemakers, for they shall be called the sons of God,” Matt., v. 9) with Wisdom, both as regards their merit, and as regards their reward. The work of Wisdom is to reduce all things to unity, to see life and the world as a whole, to look upon creatures as parts of one great divine plan. Similarly, the work of the peacemakers is to put an end to dissension and division and to reconcile the warring powers of the soul, or to introduce harmony between those that are at enmity: “The Wisdom that is from above is peaceable” (James, iii. 17). Again, the reward promised the peacemakers is that they shall be called the sons of God, and of Wisdom it may be said that it makes one the image of the Son of God, who is Eternal Wisdom.
(b) The Fruits of the Holy Ghost that are assigned to Wisdom are, with regard to God: charity, or a tender love of God (“The charity of God is poured out in our hearts,” Rom., v. 5.), joy, or delight at union with God (“Rejoice in the Lord always,” Phillip., iv. 4), peace, or security in the enjoyment of God (“There is much peace to them that love Thy law,” Ps. cxviii. 165). The Fruits that have reference to the love of neighbor are: goodness, or an internal benevolence characterized by sweetness (“The fruit of the light is in all goodness,” Eph., v. 9), and kindness, or a beneficence accompanied by cheerfulness (“The Lord loves the cheerful giver,” II Cor., ix. 7).
1620. St. James (iii. 17, 18) describes the direction which Wisdom gives to human actions (see 1612, 1613) and the fruit of peace to which it conducts them, as follows: “The Wisdom that is from above, first indeed is chaste, then peaceable; modest, easy to be persuaded; consenting to the good, full of mercy and good fruits, without judging, without dissimulation. And the fruit of justice is sown in peace to them that make peace.”
(a) Thus, first, Wisdom directs one to be free from sin (“chaste”), for the fear of the Lord is the beginning of Wisdom (Ps. cx. 110).
(b) Next, Wisdom directs one to work for peace within one’s own soul, by following moderation where one can decide for oneself (“modest”), by seeking advice where one is in doubt (“easy to be persuaded”).
(c) Further, Wisdom directs one to be peaceful towards others, to be well disposed towards their good or benefit (“consenting to the good”), compassionate and helpful in their distress (“full of mercy and good fruits”), not partial or hypocritical in criticizing their defects (“without judging, without dissimulation”).
(d) Finally, Wisdom, having sown in peace, reaps the peace of righteousness. False wisdom leads to wrangling and disorder, true Wisdom to concord and harmony.
1621. The Sins Opposed to Wisdom.—Just as blindness and dullness-that is, the want of all or of sufficient perceptiveness in spiritual things—are opposed to the Gift of Understanding (see 912), so stupidity and foolishness—that is, the want of all or of sufficient good judgment about spiritual things—are opposed to the Gift of Wisdom.
