Loving God and Neighbor (1822-1824)
By charity, we love God for his own sake and our neighbor as ourselves for the love of God.
Jesus loved us “to the end” (Jn 13:1). He told his disciples to “love one another as I have loved you” (Jn 15:9, 12). Charity keeps the commandments of God and of Christ, “If you keep my commandments, you will abide in my love” (Jn 15:9-10).
Paul’s Description (1825-1826)
Christ demands that we love everyone, especially our enemies, our neighbors and the poor. St. Paul says that love is patient and kind, believing, helping, and enduring all things. Love is not jealous, boastful, arrogant, rude, irritable, or resentful.
Without charity, “I am nothing” and “I gain nothing.” “So faith, hope, and charity abide, these three. But the greatest of these is charity” (1 Cor 13:1-13).
Love Animates the Moral Life (1827-1829)
Charity binds all virtues "together in perfect harmony (Col 3:14) and gives them order. Charity purifies and raises human love to the perfection of God’s love.
When charity animates his moral life, the Christian is free from servile fear and lives as a son responding to God who “first loved us” (1 Jn 4:19). “If we obey out of love for him who commands, we are in the position of his children” (St. Augustine).
Charity is benevolent, disinterested, and generous, bringing forth friendship and communion. “Love is the goal. Once we reach it, we shall find rest”(St. Augustine).
