Every statistic I've seen has shown equal or higher divorce rates for christians than atheists, so I don't really think that one's appropriate.
Lord, Lord, Lord.....Get away from Me, I never knew you.
Going to church does not make you a christian and many of our pewmates will not be our heavenly mates. That does not mean devout christians cannot divorce, there are two NT reasons for divorce in the bible, but these stats can be skewed somewhat when you take into consideration not everyone who calls themselves a christian, is.
