[quote:3a07xupw]Could this statistic be due to the fact that the divorce rate of Christians/Catholics is along the same lines as the NFP and non-believers the same line as those who use contraception?[/quote:3a07xupw]
Not sure if I read you correctly, but the divorce rate among U.S. Catholics is that same as the rest of the country. Catholic marriages are not synonymous with NFP.
