The Spiritual Gifts are perfections

The goal of the virtues is happiness, but the goal of the spiritual gifts are the integrity, the eternal life, the common life.
Tomas Aquinas explains an introduction of the work of Aristotle and talks about the 4 cardinal virtues: Temperance, Fortitude, Justice and Prudence. Later Tomas Aquinas says in his book Summa Theologiae: "we can only attributes perfections to God".
The virtues are not perfections, Justice is not a perfection, not all Justice is good. The 4 cardinal virtues describes an intermediate state between good and evil characterized by the passions.
Tomas Aquinas describes about the spiritual gifts of the will like Mercy, Continuous Improvement (spiritual gift of fortitude), spiritual gift of fear of the lord (constancy, firmness, devotion); and the spiritual gifts of science like spiritual gift of knowledge, spiritual gift of wisdom, and spiritual gift of discernment.
The origine of the virtue is the desire for happiness, the origine of the spiritual gifts is the desire for the good.
"Be perfect,therefore, as your heavenly Father is perfect" Matthew 5:48 is the resume of the spirituality and the Christian life.
