From The Life and Times of Bruce Gerencser:
Churches and pastors who identify with the Independent Fundamentalist Baptist (IFB) church movement generally believe that marriage is for life and that divorce is a sin. While you will find a variety of interpretations among IFB churches and pastors, I can safely say they hate divorce. The Bible says in Malachi 2:14-16:
Yet ye say, Wherefore? Because the Lord hath been witness between thee and the wife of thy youth, against whom thou hast dealt treacherously: yet is she thy companion, and the wife of thy covenant. And did not he make one? Yet had he the residue of the spirit. And wherefore one? That he might seek a godly seed. Therefore take heed to your spirit, and let none deal treacherously against the wife of his youth. For the Lord, the God of Israel, saith that he [God] hateth putting away [divorce]: for one covereth violence with his garment, saith the Lord of hosts: therefore take heed to your spirit, that ye deal not treacherously.
The Bible says that God hates divorce. IFB adherents often say they “love what God loves and hate what God hates,” so it should come as no surprise, then, that the sin of divorce is roundly hated. Not as hated as, say, homosexuality, liberalism, or sleeping during the pastor’s sermon, but definitely a top-ten sin.
