Wisdom is considered the first and the greatest of the Gifts of the Holy Ghost. It acts upon both the intellect and the will. According to St. Bernard, it both illumines the mind and instills an attraction to the divine. Adolphe Tanquerey OP explained the difference between the gift of wisdom and that of understanding: “The latter is a view taken by the mind, while the former is an experience undergone by the heart; one is light, the other love, and so they unite and complete one another.” A wise and loving heart is the perfection of the theological virtue of charity.
Understanding helps one relate all truths to one’s supernatural purpose; it further illuminates one’s understanding of Sacred Scripture; and it assists us to understand the significance of religious ritual. This gift strengthens one’s insight through prayer, scripture, and the sacraments. This all gives a person a profound appreciation for God’s providence.
Counsel functions as a sort of supernatural intuition, to enable a person to judge promptly and rightly, especially in difficult situations. It perfects the cardinal virtue of prudence. While prudence operates in accord with reason as enlightened by faith, the gift of counsel operates under the guidance of the Holy Spirit to illuminate the will of God.
Fortitude is often identified with courage, but Aquinas takes its meaning to also encompass endurance. It has been described as a willingness to stand up for what is right in the sight of God, even if it means accepting rejection, verbal abuse, or physical harm. The gift of fortitude allows people the firmness of mind that is required both in doing good and in enduring evil. It is the perfection of the cardinal virtue of the same name.
The Gift of Knowledge allows one, as far as is humanly possible, to see things from God’s perspective. It “allows us to perceive the greatness of God and his love for his creatures” through creation.
Piety accords with reverence. A person with reverence recognizes his total reliance on God and comes before God with humility, trust, and love. Thomas Aquinas says that piety perfects the virtue of religion, which is an aspect of the virtue of justice, in that it accords to God that which is due to God.
Fear of the Lord is akin to wonder (or awe). With the gift of fear of the Lord, one is made aware of the glory and majesty of God. A person with wonder and awe knows that God is the perfection of all one’s desires. This gift is described by Aquinas as a fear of separating oneself from God. He describes the gift as a “filial fear,” like a child’s fear of offending his father, rather than a “servile fear,” that is, a fear of punishment. Fear of the Lord is the beginning of wisdom. It is the perfection of the theological virtue of hope.
