We get asked this more than almost anything else in early consultations, usually by a couple hoping we'll settle it for them. We won't, because it's genuinely your decision, but here's what's actually true on both sides, without picking a winner for you.
The Christian conviction, stated plainly
The Bible's picture of marriage, the leaving and joining described in Genesis, treats the wedding itself as the threshold into a new kind of life together, not a formality tacked onto a life you'd already built. Historically, Christian teaching has understood sex and full domestic life together as belonging inside that threshold, not ahead of it. If you hold that conviction, or you're marrying someone who does, it deserves a real hearing rather than being dismissed as old fashioned. It's not arbitrary. It's a specific claim about what the wedding is actually for.
What's actually true about the research
You'll hear "couples who live together first are more likely to divorce" stated as settled fact, and it's more complicated than that. Some studies have found a correlation between cohabitation before an engagement and higher divorce rates. Other more recent research suggests the gap has narrowed significantly, and that a lot of the original effect was less about living together itself and more about who tends to move in together without a clear commitment already in place. In plain terms: the research doesn't cleanly say cohabitation ruins marriages. It suggests that drifting into a shared apartment without ever having the harder conversations about commitment is what's actually risky, whether or not you've also merged your furniture.
The actual question underneath both sides
Whichever path you're on, the same question matters more than the living arrangement itself: have you had explicit, unambiguous conversations about commitment, or has the relationship simply advanced through momentum. Two people who move in together after clearly deciding they're building toward marriage are in a very different position than two people who moved in because the lease was cheaper split two ways and never quite discussed where it was headed.
If you're already living together
This isn't a piece written to make you feel judged for a decision you've already made. If you're engaged and living together now, the conversation worth having isn't "should we undo this," it's the same one every couple needs: have you actually talked about faith, money, family, and what marriage changes, or has cohabitation quietly let you skip some of those conversations because daily life together already feels settled. That's worth checking honestly, whatever the living situation.
We'll walk through this with you directly and without judgment either way. What we care about is that the decision is one you actually made together, with your eyes open, rather than one that happened to you.
