To Florus 2.49
It is clear, then, that imitation of evil human beings is not merely a consistent expression but a necessary one. For the moment, it is evident that this argument of yours lies defeated. You add that Scripture says of the devil, ‘Those who belong to his party imitate him’ (Wisdom 2:24; Latin numbering 2:25). I too agree that the author of that book, whoever he is, said this wisely. But the statement that some sin by imitating the devil does not help you unless you show that people cannot sin by imitating human beings.
