The sound words of Augustine on this question, as based on his sound arguments, come down to us with strength and freshness through the intervening centuries; and they are worthy of being emphasized as the expressions of unchanging truth concerning the duty of truthfulness and the sin of lying. "There is a great question about lying," he says at the start, "which often arises in the midst of our everyday business, and gives us much trouble, that we may not either rashly call that a lie which is not such, or decide that it is sometimes right to tell a lie; that is, a kind of honest, well-meant, charitable lie." This question he discusses with fulness, and in view of all that can be said on both sides. Even though life or salvation were to pivot on the telling of a lie, he is sure that no good to be gained could compensate for the committal of a sin.

Arguing that a lie is essentially opposed to God's truth—by which alone man can have eternal life—Augustine insists that to attempt to save another's life through lying, is to set off one's eternal life against the mere bodily life of another. "Since then by lying eternal life is lost, never for any man's temporal life must a lie be told. And as to those who take it ill, and are indignant that one should refuse to tell a lie, and thereby slay his own soul in order that another may grow old in the flesh, what if by our committing adultery a person might be delivered from death: are we therefore to steal, to commit whoredom…. To ask whether a man ought to tell a lie for the safety of another, is just the same as asking whether for another's safety a man ought to commit iniquity."

"Good men," he says, "should never tell lies." "To tell a lie is never lawful, therefore neither to conceal [when concealment is desirable] by telling a lie." Referring to the fact that some seek to find a justification in the Bible teachings for lying in a good cause,—"even in the midst of the very words of the divine testimonies seeking place for a lie,"—he insists, after a full examination of this claim, "that those [cited] testimonies of Scripture have none other meaning than that we must never at all tell a lie."

"A lie is not allowable, even to save another from injury." "Every lie must be called a sin." "Nor are we to suppose that there is any lie that is not a sin, because it is sometimes possible, by telling a lie, to do service to another." "It cannot be denied that they have attained a very high standard of goodness who never lie except to save a man from injury; but in the case of men who have reached this standard, it is not the deceit, but their good intention, that is justly praised, and sometimes even rewarded,"—as in the case of Rahab in the Bible story. "There is no lie that is not contrary to truth. For as light and darkness, piety and impiety, justice and injustice, sin and righteousness, health and sickness, life and death, so are truth and a lie contrary the one to the other. Whence by how much we love the former, by so much ought we to hate the latter."

"It does indeed make very much difference for what cause, with what end, with what intention, a thing be done: but those things which are clearly sins, are upon no plea of a good cause, with no seeming good end, no alleged good intention, to be done. Those works, namely, of men, which are not in themselves sins, are now good, now evil, according as their causes are good or evil…. When, however, the works in themselves are evil,… who is there that will say, that upon good causes, they may be done, so as either to be no sins, or, what is more absurd, to be just sins?" "He who says that some lies are just, must be judged to say no other than that some sins are just, and that therefore some things are just which are unjust: than which what can be more absurd?" "Either then we are to eschew lies by right doing, or to confess them [when guilty of them] by repenting: but not, while they unhappily abound in our living, to make them more by teaching also."

In replying to the argument that it would be better to lie concerning an innocent man whose life was sought by an enemy, or by an unjust accuser, than to betray him to his death, Augustine said courageously: "How much braver,… how much more excellent, to say, 'I will neither betray nor lie.'" "This," he said, "did a former bishop of the Church of Tagaste, Firmus by name, and even more firm in will. For when he was asked by command of the emperor, through officers sent by him, for a man who was taking refuge with him, and whom he kept in hiding with all possible care, he made answer to their questions, that he could neither tell a lie nor betray a man; and when he had suffered so many torments of body (for as yet emperors were not Christians), he stood firm in his purpose. Thereupon, being brought before the emperor, his conduct appeared so admirable that he without any difficulty obtained a pardon for the man whom he was trying to save. What conduct could be more brave and constant?"[1]

The treatise "Against Lying" was written by Augustine with special reference to the practice and teaching of the sect of Priscillianists. These Christians "affirmed, with some other of the theosophic sects, that falsehood was allowable for a holy end. Absolute veracity was only binding between fellow-members of their sect."[1] Hence it was claimed by some other Christians that it would be fair to shut out Priscillianists from a right to have only truth spoken to them, since they would not admit that it is always binding between man and man. This view of truthfulness as merely a social obligation Augustine utterly repudiated; as, indeed, must be the case with every one who reckons lying a sin in and of itself. Augustine considered, in this treatise, various hypothetical cases, in which the telling of the truth might result in death to a sick man, while the telling of a falsehood might save his life. He said frankly: "And who can bear men casting up to him what a mischief it is to shun a lie that might save life, and to choose truth which might murder a man? I am moved by this objection exceedingly, but it were doubtful whether also wisely." Yet he sees that it were never safe to choose sin as a means to good, in preference to truth and right with all their consequences.

Jerome having, like many others, adopted Origen's explanation of the scene between Peter and Paul at Antioch, Augustine wrote to him in protest against such teaching, with its implied approval of deceit and falsehood.[1] A correspondence on this subject was continued between these two Fathers for years;[2] and finally Jerome was led to adopt Augustine's view of the matter,[3] and also to condemn Origen for his loose views as to the duty of veracity.[4] But however Jerome might vacillate in his theory, as in his practice, concerning the permanent obligations of truthfulness, Augustine stood firm from first to last in the position which is justified by the teachings of the Bible and by the moral sense of the human race as a whole,—that a lie is always a lie and always a sin, and that a lie can never be justified as a means to even the best of ends.
