Tolerance
When tolerance of points of view comes from a heart that is pure and cleansed of all evil, that tolerance is not liable to chill the flame of holy feelings containing simple faith—which is the source of all life. Instead, that tolerance broadens and magnifies the foundation of heaven-directed fervor. Tolerance is armed with a very great faith. Ultimately, it realizes the complete impossibility of a soul being emptied of all holy life. This is because the life of the living God fills all life.
