If now it should happen, as I pray it may not happen nor at any time fall out, that there be a war against churches, and a persecution, imagine how great will be the ridicule, how sore the reproaches. And very naturally; for when no one exercises himself in the wrestling school, how shall he be distinguished in the contests? What champion, not being used to the trainer, will be able, when summoned by the Olympic contests, to show forth anything great and noble against his antagonist? Ought we not every day to wrestle and fight and run? See ye not them that are called Pentathli, when they have no antagonists, how they fill a sack with much sand, and hanging it up try their full strength thereupon? And they that are still younger, practise the fight against their enemies upon the persons of their companions.
