Chapter 30 — Part III: The Decalogue — The Seventh Commandment
Section 3. Our gratitude to God, the author of this law, should be in proportion to the greatness of the benefit the law confers upon us. Now since the truest test of gratitude and the best means of returning thanks, consists not only in lending a willing ear to His precepts, but also in obeying them, the faithful are to be animated and encouraged to an observance of this Commandment.
