Chapter 31 — Part III: The Decalogue — The Eighth Commandment
Section 49. There remain two other classes of persons who seek to justify lying: those who say that they tell lies for the sake of amusement, and those who plead motives of interest, claiming that without recourse to lies, they can neither buy nor sell to advantage. The pastor should endeavour to reform both these kinds of liars. He should correct the former by showing how strong a habit of sinning is contracted by their practice, and by strongly impressing upon them the truth that for every idle word they shall render an account. As for the second class, he should upbraid them with greater severity, because their very excuse is a most serious accusation against themselves, since they show thereby that they yield no faith or confidence to these words of God: Seek first the kingdom of God and his justice, and all these things shall be added unto you.
