The Bible teaches that there may be no remarriage unless one's spouse has died. Some claim that two New Testament passages especially are grounds for remarriage after divorce, even when one's spouse is still living.

The floodgates have been opened, allowing to be swept away the blessed institution of marriage. In every other passage of scripture, God makes it very plain that he does not allow remarriage.
