So when modern-day religious conservatives wax nostalgic about how marriage is a sacred tradition that reaches back into history for thousands of uninterrupted years, they are correct, but in only one respect - only if they happen to be talking about Judaism. Christianity simply does not share that deep and consistent historical reverence toward matrimony. Lately it has, yes- but not originally. For the first thousand or so years of Christian history, the church regarded monogamous marriage as marginally less wicked that flat-out whoring but only very marginally.
