Adultery the Only Reason for Divorce—A woman may be legally divorced from her husband by the laws of the land and yet not divorced in the sight of God and according to the higher law. There is only one sin, which is adultery, which can place the husband or wife in a position where they can be free from the marriage vow in the sight of God. Although the laws of the land may grant a divorce, yet they are husband and wife still in the Bible light, according to the laws of God. TSB 78.4
I saw that Sister Jones, as yet, has no right to marry another man; but if she, or any other woman, should obtain a divorce legally on the ground that her husband was guilty of adultery, then she is free to be married to whom she chooses.—The Adventist Home, 344. TSB 79.1
Among the Jews a man was permitted to put away his wife for the most trivial offenses, and the woman was then at liberty to marry again. This practice led to great wretchedness and sin. In the Sermon on the Mount Jesus declared plainly that there could be no dissolution of the marriage tie except for unfaithfulness to the marriage vow. “Everyone,” He said, “that putteth away his wife, saving for the cause of fornication, maketh her an adulteress: and whosoever shall marry her when she is put away committeth adultery” (Matthew 5:32, R.V.). TSB 79.2
When the Pharisees afterward questioned Him concerning the lawfulness of divorce, Jesus pointed His hearers back to the marriage institution as ordained at creation. “Because of the hardness of your hearts,” He said, Moses “suffered you to put away your wives: but from the beginning it was not so” (Matthew 19:8). He referred them to the blessed days of Eden, when God pronounced all things “very good.” Then marriage and the Sabbath had their origin, twin institutions for the glory of God in the benefit of humanity. Then, as the Creator joined the hands of the holy pair in wedlock, saying, A man shall “leave his father and his mother, and shall cleave unto his wife: and they shall be one” (Genesis 2:24), He enunciated the law of marriage for all the children of Adam to the close of time. That which the Eternal Father Himself had pronounced good was the law of highest blessing and development for man.—Thoughts From the Mount of Blessing, 63. TSB 79.3
Change Disposition, Not the Marriage Status—I have received a letter from your husband. I would say that there is only one thing for which a husband may lawfully separate from his wife or a wife from her husband, and that is adultery. TSB 80.1
If your dispositions are not congenial, would it not be for the glory of God for you to change these dispositions? TSB 80.2
A husband and wife should cultivate respect and affection for each other. They should guard the spirit, the words, and the actions so that nothing will be said or done to irritate or annoy. Each is to have a care for the other, doing all in their power to strengthen their mutual affection. TSB 80.3
I tell you both to seek the Lord. In love and kindness do your duty one to the other. The husband should cultivate industrious habits, doing his best to support his family. This will lead his wife to have respect for him.—The Adventist Home, 345. TSB 80.4
