I used to believe in JW virgin marriage.
Now, I think that a couple should live together for 2 years before making that monumental decision (without pregnancy).
As for religionism's imposition - Dub's copy Christendom's (Hello FDS, and not copying Christendom) interpretation of the 3-fold cord - i.e. that the third cord means God is in your marriage.
Calling bullshit - that verse has nothing to do with God or marriage.
