The church didn't require this when the wife and I got married in the Philippines but BOY the Navy did.
Took us 2 years from the time I asked for her hand before the Navy gave us permission to get married.
All types of counseling, pressure, paperwork, etc.
It also helps to discuss this ahead of time.
Both of us knew, going into marriage, that neither of us believed in divorce.
I didn't believe in it either, until I found myself in a situation where it became a necessity, in order to literally save my life.
