Pusillanimity, a virtually obsolete word, is the name of a heresy rampant in the world today. Most people have never heard of it, but it has some important thought elements which make it useful in pursuing the spiritual life. Therefore, Orthodox Christians should consider it carefully. Pusillanimity denotes spiritual cowardice, lack of “manly” strength, spiritual inertia, a certain diminution of faith and trust in God.
