It’s a matter of documentable and observable fact that Europe is now a collection of post-Christian nations. Though revival can and does happen in the darkest of place, facts for the moment are that church attendance there is beyond abysmal. Christian institutions such as marriage, baptism, etc. are by and large becoming things of the past. Couples in Europe (regardless of the definition of the notion of a “couple”) don’t bother getting married anymore. They just shack, have kids, and if the relationship fizzles – move on. There is nothing binding them like a marriage license or vows made before an Almighty deity.
