Against Heresies

Now, however, inasmuch as the books of these men may possibly have escaped your observation, but have come under our notice, I call your attention to them, that for the sake of your reputation you may expel these writings from among you, as bringing disgrace upon you, since their author boasts himself as being one of your company. For they constitute a stumbling-block to many, who simply and unreservedly receive, as coming from a presbyter, the blasphemy which they utter against God. Just [consider] the writer of these things, how by means of them he does not injure assistants [in divine service] only, who happen to be prepared in mind for blasphemies against God, but also damages those among us, since by his books he imbues their minds with false doctrines concerning God.
