"Our educational work should go this way to achieve harmony - harmony in all the boys and girls who have been entrusted to us; inner harmony, the harmony of their personality. It is by working in a hands-on way, imitating God, molding the lives of those kids like clay, that we achieve harmony and rescue them from the dissonances perennial darkness. Harmony, by contrast, is bright and clear; it is light. What we have to achieve is the harmony of a heart that grows and that we accompany in this educational journey."
~ Pope Francis (then, Cardinal Bergoglio – April 18, 2012)
