One of the Gifts of the Holy Spirit:
Wisdom is one of the seven gifts of the Holy Spirit
enumerated in Isaiah 11:2-3. They are present in their fullness in Jesus Christ, Whom Isaiah foretold (Isaiah 11:1), but they are available to all Christians who are in a state of grace. We receive the seven gifts of the Holy Spirit when we are infused with sanctifying grace, the life of God within us—as, for example, when we receive a sacrament
worthily. As the current Catechism of the Catholic Church notes, "They complete and perfect the virtues of those who receive them."
The First and Highest Gift of the Holy Spirit:
Wisdom is the perfection of faith. As Fr. John A. Hardon, S.J., notes in his Modern Catholic Dictionary, "Where faith is a simple knowledge of the articles of Christian belief, wisdom goes on to a certain divine penetration of the truths themselves." The better we understand those truths, the more we value them properly. Thus wisdom, the Catholic Encyclopedia notes, "by detaching us from the world, makes us relish and love only the things of heaven." Through wisdom, we judge the things of the world in light of the highest end of man—the contemplation of God.
The Application of Wisdom:
Such detachment, however, is not the same as renunciation of the world—far from it. Rather, wisdom helps us to love the world properly, as the creation of God, rather than for its own sake. The material world, though fallen as a result of the sin of Adam and Eve, is still worthy of our love; we simply need to see it in the proper light, and wisdom allows us to do so.
Knowing the proper ordering of the material and spiritual worlds through wisdom, we can more easily bear the burdens of this life and respond to our fellow man with charity and patience.
