8 For is there anything so reprobate as that which excites to luxury, to corruption, to wantonness, as the incentive to lust, the enticer to pleasure, the fuel of incontinence, the firebrand of desire? What new school has sent out these Epicureans? Not a school of philosophers, as they themselves say, but of unlearned men who preach pleasure, persuade to luxury, esteem chastity to be of no use. They were with us, but they were not of us, for we are not ashamed to say what the Evangelist John said. But when settled here they used to fast at first, they were enclosed within the monastery, there was no place for luxury, the opportunity of mocking and disputing was cut off.
