3. For my part, as a Manichæan, this verse has little difficulty for me, for at the outset I am taught to believe that many things which pass in Scripture under the name of the Saviour are spurious, and that they must therefore be tested to find whether they are true, and sound, and genuine; for the enemy who comes by night has corrupted almost every passage by sowing tares among the wheat. So I am not alarmed by these words, notwithstanding the sacred name affixed to them; for I still claim the liberty to examine whether this comes from the hand of the good sower, who sows in the day-time, or of the evil one, who sows in the night. But what escape from this difficulty can there be for you, who receive everything without examination, condemning the use of reason, which is the prerogative of human nature, and thinking it impiety to distinguish between truth and falsehood, and as much afraid of separating between what is good and what is not as children are of ghosts? For suppose a Jew or any one acquainted with these words should ask you why you do not keep the precepts of the law and the prophets, since Christ says that he came not to destroy but to fulfill them: you will be obliged either to join in the superstitious follies of the Jews, or to declare this verse false, or to deny that you are a follower of Christ.
