Chapter 24 — Part III: The Decalogue — The First Commandment
Section 46. This jealousy of God, since it shows His boundless and incomprehensible goodness towards us, we find most sweet and pleasant. Among men there is no love more ardent, no greater or more intimate tie, than that of those who are united by marriage. Hence when God frequently compares Himself to a spouse or husband and calls Himself a jealous God, He shows the excess of His love towards us.
