Witnesses to this truth abound in the tradition. St. Athanasius, in his classic Life of St. Anthony, describes Anthony’s victories over temptation and then refers his words to the enemy: “You, then, are much to be despised, for you are black of mind, and like a powerless child. From now on, you cause me no anxiety, for the Lord is my helper, and I shall look upon my enemies [Ps 117:7]. Hearing these words, the black one immediately fled, cowering at the words and afraid even to approach the man” (pg. 35).
