3.
Augustin replies: You warn against semi-Christians, which you say we are; but we warn against pseudo-Christians, which we have shown you to be. Semi-Christianity may be imperfect without being false. So, then, if the faith of those whom you try to mislead is imperfect, would it not be better to supply what is lacking than to rob them of what they have? It was to imperfect Christians that the apostle wrote, "joying and beholding your conversation," and "the deficiency in your faith in Christ." 1 The apostle had in view a spiritual structure, as he says elsewhere, "Ye are God's building;" 2 and in this structure he found both a reason for joy and a reason for exertion. He rejoiced to see part already finished; and the necessity of bringing the edifice to perfection called for exertion. Imperfect Christians as we are, you pursue us with the desire to pervert what you call our semi-Christianity by false doctrine; while even those who are so deficient in faith as to be unable to reply to all your sophisms, are wise enough at least to know that they must not have anything at all to do with you. You look for semi-Christians to deceive: we wish to prove you pseudo-Christians, that Christians may learn something from your refutation, and that the less advanced may learn to avoid you. Do you call us children of the serpent? You have surely forgotten how often you have found fault with the prohibition in Paradise, and have praised the serpent for opening Adam's eyes. You have the better claim to the title which you give us. The serpent owns you as well when you blame him as when you praise him.
