19. Nemesianus of Tubunæ has advanced many passages of Scripture to prove his point; but he has in fact said much on behalf of the view of the Catholic Church, which we have undertaken to set forth and maintain. Unless, indeed, we must suppose that he does not "trust in what is false" who trusts in the hope of things temporal, as do all covetous men and robbers, and those who renounce the world in words but not in deeds, of whom Cyprian yet bears witness that such men not only baptize, but even are baptized within the Church.[424] For they themselves also "follow flying birds,"[425] since they do not attain to what they desire. But not only the heretic, but every one who leads an evil life, "deserteth the ways of his own vineyard, and hath strayed from the paths of his own field. And he walketh through pathless and dry places, and a land destined to thirst; and he gathereth fruitless weeds in his hands;" because all justice is fruitful, and all iniquity is barren. Those, again, who "drink strange water out of a strange fountain," are found not only among heretics, but among all who do not live according to the teaching of God, and do live according to the teaching of the devil. For if he were speaking of baptism, he would not say, "Do not drink of a strange fountain," but, do not wash thyself in a strange fountain. Again, I do not see at all what aid he gets towards proving his point from the words of our Lord, "Except a man be born of water and of the Spirit, he cannot enter into the kingdom of God."[426] For it is one thing to say that every one who shall enter into the kingdom of heaven is first born again of water and the Spirit, because except a man be born of water and of the Spirit, he shall not enter into the kingdom of heaven, which is the Lord's saying, and is true; another thing to say that every one who is born of water and the Spirit shall enter into the kingdom of heaven, which is assuredly false. For Simon Magus also was born of water and of the Spirit,[427] and yet he did not enter into the kingdom of heaven; and this may possibly be the case with heretics as well. Or if only those are born of the Spirit who are changed with a true conversion, all who renounce the world in word and not in deed are assuredly not born of the Spirit, but of water only, and yet they are within the Church, according to the testimony of Cyprian. For we must perforce grant one of two things,--either those who renounce the world deceitfully are born of the Spirit, though it is to their destruction, not to salvation, and therefore heretics may be so born; or if what is written, that "the Holy Spirit of discipline will flee deceit,"[428] extends to proving as much as this, that those who renounce the world deceitfully are not born of the Spirit, then a man may be baptized with water, and not born of the Spirit, and Nemesianus says in vain that neither the Spirit can work without the water, nor the water without the Spirit. Indeed it
