You said "first marriage" twice in your first post. Did you mean marriage before co-habitation? Is that what the statistics said?
But in any case we must take into account that in western societies it is unusual for young people to get married before living together while for older people it wouldn't be so unusual.
No. I think I made that clear.
People who co-habitate before their first marriage are far more likely to get a divorce than people who do not co-habitate before their first marriage. By a large margin.
When you get to second and third marriages, it gets more complicated. More variables, I suppose. However, it is also true that second and third marriages are more likely to fail than first (and only) ones are.
I was attempting to both keep things simple....and accurate.
the question, after all, was whether the reader thought that cohabitation before marriage was a sin. I do.
........even if the goal was to find out if the two people were compatible. It still is a sin, according to my beliefs, but it's ALSO a bad idea and counter productive. Now whether or not something is a 'sin' depends upon belief systems and opinions, and also on the culture. However, the fact that doing so is counter-productive in terms of establishing combatibility? THAT can be evaluated and conclusions drawn by looking at divorce stastistics.
So...people who live together before marriage (at least their first one) are more likely to get divorced than people who don't.
So much for that idea.
