I said the bible was the last place to look for advice on marriage and divorce. It would appear that the only reason for divorce is infidelity when there are other serious problems that can affect a marriage.
Why for example, should a woman have to remain in a marriage with an abusive partner? Why should she have to live in constant fear of a beating or verbal onslaught? Some women can also be abusive to their husbands. Of course, the abused partner can leave, but they should be free to divorce and remarry.
A couple may drift apart. Fall out of love if you wish. Why should they not divorce and remarry? Would you deny them the right to find love again?
If there is infidelity, mental and physical abuse, or simply a complete lack of love in a relationship then it can't be called a marriage and people should be free to leave such a relationship and remarry if they so desire.
Thankfully people nowadays can divorce for all of those reasons, but not so if you follow biblical advice.
Biblical advice on marriage and divorce belongs in the age in which it was written.
