Divorce and Remarriage

I thought I would try to offer a few thoughts on things that we can agree on. I came across this post on Between Two Worlds. Here is a passage from the article by David Instone-Brewer

What God Has Joined: What does the Bible really teach about divorce?

Putting all this together gives us a clear and consistent set of rules for divorce and remarriage. Divorce is only allowed for a limited number of grounds that are found in the Old Testament and affirmed in the New Testament:

* Adultery (in Deuteronomy 24:1, affirmed by Jesus in Matthew 19)
* Emotional and physical neglect (in Exodus 21:10-11, affirmed by Paul in 1 Corinthians 7)
* Abandonment and abuse (included in neglect, as affirmed in 1 Corinthians 7)

Jewish couples listed these biblical grounds for divorce in their marriage vows. We reiterate them as love, honor, and keep and be faithful to each other. When these vows were broken, it threatened to break up the marriage. As in any broken contract, the wronged party had the right to say, "I forgive you; let's carry on," or, "I can't go on, because this marriage is broken."

Therefore, while divorce should never happen, God allows it (and subsequent remarriage) when your partner breaks the marriage vows.

I was really encouraged by this and felt that we could all be on the same page here until I realized that many complemetarian leaders do not teach this at all. John Piper teaches no remarriage at all. Now I am all the more confused. I set out to write about how happy I was to read this. I know I agree with it but I am not so sure about what others think.
