St. Maximus the Confessor here makes clear the nature of true charity or love of God (one of the theological virtues), and affirms that it is not by faith alone that we secure our salvation, but also by a positive act of love of God and expressed in generosity and good works, particularly in long-suffering service to our neighbor.
Charity [caritas or agape in Greek] is a right attitude of mind which prefers nothing to the knowledge of God. If a man possesses any strong attachment to the things of this earth, he cannot possess true charity. For anyone who really loves God prefers to know and experience God rather than his creatures. The whole set and longing of his mind is ever directed toward him.
For God is far superior to all his creation, since everything which exists has been made by God and for him. And so, in deserting God, who is beyond compare, for the inferior works of creation, a man shows that he values God, the author of creation, less than creation itself.
The Lord himself reminds us: Whoever loves me will keep my commandments. And this is my commandment: that you love one another. So the man who does not love his neighbor does not obey God’s command. But one who does not obey his command cannot love God. A man is blessed if he can love all men equally. Moreover, if he truly loves God, he must love his neighbor absolutely. Such a man cannot hoard his wealth. Rather, like God himself, he generously gives from his own resources to each man according to his needs.
Since he imitates God’s generosity, the only distinction he draws is the person’s need. He does not distinguish between a good man and a bad one, a just man and one who is unjust. Yet his own goodness of will makes him prefer the man who strives after virtue to the one who is depraved.
A charitable mind is not displayed simply in giving money; it is manifested still more by personal service as well as by the communication of God’s word to others: In fact, if a man’s service toward his brothers is genuine and if he really renounces worldly concerns, he is freed from selfish desires. For he now shares in God’s own knowledge and love. Since he does possess God’s love, he does not experience weariness as he follows the Lord his God. Rather, following the prophet Jeremiah, he withstands every type of reproach and hardship without even harboring an evil thought toward any man.
For Jeremiah warns us: Do not say: “We are the Lord’s temple”. Neither should you say: “Faith alone in our Lord Jesus Christ can save me.” By itself faith accomplishes nothing. For even the devils believe and shudder.
No, faith must be joined to an active love of God which is expressed in good works. The charitable man is distinguished by sincere and long-suffering service to his fellow man: it also means using things aright.
This selection from the chapters On Charity by Saint Maximus the confessor (Chapters on Charity Centuria 1, cap. 1, 4-5, 16-17, 23-24, 26-28, 30-40; PG 90, 962-967) makes clear the nature of true charity or love of God (one of the theological virtues) on caritas (agape) and the generosity of authentic love. It is used in the Roman Catholic Office of readings for Sunday of the seventh (7th) week in ordinary time with the accompanying biblical reading taken from Eccelesiastes 1:1-18.
