"But I need not invoke the example of those far distant from us in the past. With our own eyes we have often seen women and still youthful maidens endure the torments of tyrants in witness to their faith. What is needed in those who do battle for the truth and for God is courage not of body but of spirit. For victory is to be sought by the darts of prayer not by iron javelins, and it is faith that enables one to endure the combat. Thus armed, take up the standard of Christ's cross and follow him."
Origen (AD 185-253), In lib. Judicum, hom. VII: PG 12, 986-988
