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.

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.
