Or peradventure, doth the person who lies then utter false witness when he either invents or hides any man’s sin, or hurts any man in whatever way? For, if a lie spoken against a man’s temporal life is detestable, how much more one against eternal life? as is every lie, if it take place in doctrine of religion. And it is for this reason that the Apostle calls it false witness, if a man tell a lie about Christ, yea, one which may seem to pertain to His praise. Now if it be a lie that neither inventeth or hideth any man’s sin, nor is answered to a question of the judge, and hurteth no man, and profits some man, are we to say that it is neither false witness, nor a reprehensible lie?
