**EXPOSITION OF THE MORAL LAW.**
Moreover, when spouses are made aware that their union is blessed by the Lord, they are thereby reminded that they must not give way to intemperate and unrestrained indulgence. For though honourable wedlock veils the turpitude of incontinence, it does not follow that it ought forthwith to become a stimulus to it. Wherefore, let spouses consider that all things are not lawful for them. Let there be sobriety in the behaviour of the husband toward the wife, and of the wife in her turn toward the husband; each so acting as not to do any thing unbecoming the dignity and temperance of married life. Marriage contracted in the Lord ought to exhibit measure and modesty—not run to the extreme of wantonness. This excess Ambrose censured gravely, but not undeservedly, when he described the man who shows no modesty or comeliness in conjugal intercourse, as committing adultery with his wife. See Ambros. Lib. de Philosoph., quoted by Augustine in his book, Contra Julian, Lib. 2. THOU SHALT NOT STEAL.
