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.

God is good

The good is a nature, a spiritual gift and a mood of discern:
The good as a nature:
Aristotle in his book "Politic" explains that a nature is toward what the being tends in its development, example: the nature of the worm is the butterfly.
Thomas Aquinas father of the scholasticism take this idea and affirm that the good is a nature, every being tends towards his own good or perfection explains, example: the house is good when it is finished, the fruit is good when in mature.

The good as spiritual gift:
Thomas Aquinas explains that the good is a spiritual gift. God is the source of the good. "Only God is good" Mark 10:18. The good is a perfection of god, we inherit the good from God.
The good as Spiritual Gift is known as the Golden Rule: "Do unto others as you would have them do unto you" Matthew 7:12, this is also known as imitating Jesus. A practical case of this rule is the parable of the  Good Samaritan. Luke 10: 29-37

The good as a discernment:
Good and evil are lifestyles. The good as discernment is one of the seven gifts of the Holy Spirit. The spiritual gift of good discernment accompanies the spiritual gift of knowledge and the gift of wisdom after the Gnosis. The goal of this spiritual gift is to separate what is wrong from what is right, this gift in religion is directly related with the Holy Spirit.
