Fruits of the Spirit

The fruits of the spirit are perfections, spiritual gifts, blessings, but they are not beatitudes. The beatitudes are promises and perfections.
The fruits of the spirit and the works of the flesh are the ultimate results of our actions. All beings tends towards its own good or perfection. Like the tree that bear fruits when it reaches its own perfection, the man bears fruits of the spirit when he attains his integrity. When we live righteously we bear the fruits of the spirit (Galatians 5:22-23), when we sin we bear the works of the flesh (Galatians 5:19-21). The works of the flesh are not fruits because they are not delectable, pleasant.
Basically the fruits of the spirit as Tomas Aquinas says are: Charity, joy and peace, the first three are the fruits related directly with God. The rest of the fruits: forbearance, kindness goodness, faithfulness, gentleness, self control are related with the neighbor.
