Legal Marriage for Love-Free Couples

I don't think it's a bad thing that they don't want to have kids. You can have legal marriage for child-free couples and still say they're missing the point of marriage. I honestly doubt we will turn back the needle on marriage anytime soon, but at the very least we can reasonably explain what we believe about marriage. We should live out our own marriages and find their objective fulfillment in lifelong monogamy that is open to life.
