But the greatest of these is charity. Charity upholds and purifies our human ability to love, and raises it to the supernatural perfection of divine love. The practice of the moral life animated by charity gives to the Christian the spiritual freedom of the children of God. If we pursue the enticement of wages, . . . Finally if we obey for the sake of the good itself and out of love for him who commands . . .
Love is itself the fulfillment of all our works.
The moral life of Christians is sustained by the gifts of the Holy Spirit. These are permanent dispositions which make man docile in following the promptings of the Holy Spirit. The seven gifts of the Holy Spirit are wisdom, understanding, counsel, fortitude, knowledge, piety, and fear of the Lord. They belong in their fullness to Christ, Son of David. They complete and perfect the virtues of those who receive them.
