The Vertical infuses the Horizontal

"And it is only by the observance of the first and  greatest commandment that we can keep the second.  The more we love God, the more we shall love man;  the less we love God, the less we shall, in the true  sense of the word, love man. Our love will become  capricious, fitful, and unreliable—not charity, but  passion. If you feel that your love for your fellowman  is dying out in the fumes of selfishness, there is but  one way to revive it: strive for, pray for, the  love of God.  As the heart turns toward its source, it will be  quickened and expanded. There is no true, no l asting spirit of charity apart from the practice  of religion. Therefore, we cannot keep those  commandments which teach us our duty to men unless we are keeping those which teach us our duty to God." — Fr. Basil W. Maturin, Christian Self-Mastery, p. 160
