The continual study of those, who, like missionaries, are destined to instruct others ought to be this: to take care to put off themselves and to put on Jesus Christ. For, as things, for the most part, produce results in accordance with their nature----if he who gives the spirit and form of life to others is animated by a merely human spirit, what can they do but imbibe the same spirit, and learn from him the appearance of virtue rather than its substance.----St. Vincent de Paul
