For the family, the most loving thing to do with a failing marriage is end it. It wouldn't be fair to force a couple who have married to live an devastatingly unhappy marriage together that could tear up the rest of the family. As Christians it says in the bible that Christians should always do the most loving thing, this is the most loving thing to do in the situation. T
Yes, according to the Bible and the words of Jesus, yes it is acceptable for Christians to seek divorce. However, there is only one instance that Jesus allows for divorce and that is marrital unfaithfulness. Jesus declares that He still thinks it is better to not get divorced, but He does allow for it.
There seems to be no prohibition on divorce in Christianity, as long as there is just cause. So there should be no blanket prohibition on divorce. The Catholic interpretation on admonitions against divorce (such as without just cause) appear to be more about control and placing a priest between the Christian and God.
This is only one of the many places in scripture that divorce is strictly forbidden by Jesus, Paul, etc. "To the married I give charge, not I but the Lord, that the wife should not separate from her husband (but if she does, let her remain single or else be reconciled to her husband)—and that the husband should not divorce his wife" (1 Cor. 7:10–11). "For I hate divorce, says the Lord the God of Israel" (Mal. 2:16).
The supposed exception--marital unfaithfulness or unchastity--goes against these and other passages, which should make one think intently about what it means. The Greek word here, "porneia," is not the usual word for adultery, "moicheia," but is instead a word for unlawful sexual intercourse. This would seem to say that some sort of "common law marriage," so to speak, but not a real Christian marriage, could be ended. This point is reinforced by Saint Paul talking about unbelieving husbands and wives: "If the unbelieving partner desires to separate, let it be so; in such a case the brother or sister is not bound. For God has called us to peace" (1 Cor. 7:15). This so-called marriage of a believer to an unbeliever does not seem to be on the same level as a true christian marriage.
Thus, the probable conclusion is that marriages which are unlawful or not real may end in "divorce" so to speak, but this does not take away from Jesus' and Paul's repeated assertions that divorce is unacceptable.
