Chapter 27 — Part III: The Decalogue — The Fourth Commandment
Section 7. This order of the Commandments is especially appropriate, since the very collocation points out to us their difference in nature. For whatever is commanded or prohibited in Scripture by the divine law springs from one of two principles, the love of God or of our neighbour: one or the other of these is the basis of every duty required of us. The three preceding Commandments teach us the love which we owe to God; and the other seven, the duties which we owe to our neighbour and to public society. The arrangement, therefore, which assigns some of the Commandments to the first and others to the second table is not without good reason.
