“However, it would be interesting to know what percentages of divorce or marital estrangement those churches’ clergy have, and whether there’s a trend to more or less marital disruption.”
For the Orthodox its rather lower than the general population but in part that may be explained by the fact that all priests must marry, if at all, before ordination and cannot be married after so the skewing of divorce rates in the general population by serial divorce and remarriage won’t occur among clerical marriages.
Good point. One might also expect fewer divorces absolutely, vs. a random group of first-marriages, in a population where remarriage is not option. Most people don’t seem to get divorced just in order to live alone the rest of their lives!
