40. Hence, We renew the urgent entreaty We have already made, to redouble zeal and perseverance, when addressing humble supplications to our merciful God, so that the virtues whereby a Christian life is perfected may be reawakened. It is, however, urgent before all, that charity, which is the main foundation of the Christian life, and apart from which the other virtues exist not or remain barren, should be quickened and maintained. Therefore is it that the Apostle Paul, after having exhorted the Colossians to flee all vice and cultivate all virtue, adds: "Above all things, have charity, which is the bond of perfection."(⁴¹) Yea, truly, charity is the bond of perfection, for it binds intimately to God those whom it has embraced and with loving tenderness, causes them to draw their life from God, to act with God, to refer all to God. Howbeit, the love of God should not be severed from the love of our neighbour, since men have a share in the infinite goodness of God and bear in themselves the impress of His image and likeness. "This commandment we have from God, that he who loveth God, love also his brother."(⁴²) "If any man say I love God, and he hateth his brother, he is a liar."(⁴³) And this commandment concerning charity its divine proclaimer styled new, not in the sense that a previous law, or even nature itself, had not enjoined that men should love one another, but because the Christian precept of loving each other in that manner was truly new, and quite unheard of in the memory of man. For, that love with which Jesus Christ is beloved by His Father and with which He Himself loves men, He obtained for His disciples and followers that they might be of one heart and of one mind in Him by charity, as He Himself and His Father are one by their nature.
