Tony I appreciate your passion but let's stick to the facts. This study is about RELIGIOUS people, not just Christians. The conclusion OS that if you are serious about your faith then you are also diligent in your marriage. That certainly applies to regenerate believers,but the study included other religions too.
It clearly explains why there is a discrepancy between their conclusion and that of the barnum polls you mention.
These sociologists define "religious" as someone who is ACTIVE as defined by certain criteria. For ACTIVE believers there is a significantly lower divorce rate whereas those that simply IDENTIFY themselves as religious without meeting the criteria to consider them ACTIVE had little to no difference from the general divorce rate.
This is a distinction that doesn't appear in the barnum polls. Therefore the discrepancy in the conclusions.
This how science works. You refine your research methods and criteria to get more specific data and more accurate conclusions.
Tom, you didn't read the article. This new study drills down into the actual PRACTICE of Christianity. Nominal Christians are actually hypocrites who have a higher divorce rate than secular people. We who are genuinely BORN AGAIN and FILLED WITH THE HOLY SPIRIT have a much lower divorce rate. I would rather shoot myself than divorce my wife. That's because I'm a REAL CHRISTIAN.
