From the Catechism - Charity Charity 1822 Charity is the theological virtue by which we love God above all things for his own sake, and our neighbor as ourselves for the love of God. Jesus makes charity the new commandment. By loving one another, the disciples imitate the love of Jesus which they themselves receive. If you keep my commandments, you will abide in my love. The practice of the moral life animated by charity give to the Christian the spiritual freedom of the children of God.
Love is itself the fulfillment of all our works.
St. Basil, Reg.
