The Holy Spirit is the immediate source of all holiness. The missionary must above all things be a holy man. The ideal teacher … is a holy man. He is entirely sincere, and perfect in love. He is magnanimous, generous, benign, and full of forbearance. He is pure in heart, free from selfishness, and never swerves from the path of duty in his conduct. He is deep and active like a fountain, sending forth his virtues in due season. He is seen, and men revere him; he speaks, and men believe him; he acts, and men are gladdened by him. He possesses all heavenly virtues.  He is one with Heaven.
