When those who have acquired moral stability and contemplative knowledge employ these for the sake of human glory, merely conveying an outward impression of the virtues, and uttering words of wisdom and knowledge without performing the corresponding actions; and when in addition they display to others their vanity because of this supposed virtue and knowledge, then they are rightly handed over to commensurate hardships, in order to learn through suffering that humility which was unknown to them before because of their empty conceit.
—St Maximos the Confessor
