In a week when marriage made headlines, the quiet moments will be the ones I remember.

Glimpsing small cousins plodding down the aisle in tiny tuxedos, child-sized versions of the grooms they may one day become.

Chasing an exasperating (yet still adorable) toddler around the back of church while the priest asks if the couple will accept children and bring them up with love.

Catching only one line from the homily in its entirety, words quoted from Bonhoeffer that it is not the love that sustains your marriage, but from now on, the marriage that sustains your love.

Hearing a father with a golden voice singing for his daughter as she lit a candle with her new husband.

Saying yes to the bright-eyed boy who asked to take his off his too-tight dress shoes and run free through the lush grass of the golf course green.

Spinning my baby on my hip as he tipped back his head and belly-laughed with glee, wondering whether he’ll ever spin me around another mother-son dance some day.

Late-night mugging for the camera in the photo booth, catching my husband on the cheek with a kiss as so many couples have done before us.

Watching one last burst of fireworks as we pulled out of the parking lot with two tired boys fading fast in the back and a squeeze on the hand from the spouse who knows I love summer night surprises like a six year-old child.

Beyond the headlines, the everyday work of marriage goes on as before. Work and joy, children and responsibility, forgiveness and laughter.

It is a seemingly impossible promise, to choose a covenant with another flawed human being for the rest of your days. But quietly behind the scenes, millions make it happen without fanfare.

Every wedding we attend, ever since our own, I watch the high hopes of the couple at the altar, standing together in contrasting white and black, and I wonder how fitting it is to pledge love in a place of sacrifice, of lives laid down and broken in gift for each other. We are pointed towards the mystery and crucible of the sacrament long before we can glimpse the long view of what we have promised.

It’s tempting, once you’re no longer newlyweds and have reached the point of settledness—having set up house and established careers and had a few babies—to start sounding more like the seasoned old-timers, whispering while we watch them take their vows: “They’re just kids! They have no idea what’s ahead of them.”

It’s partly true: they don’t. We didn’t. No couple who commits themselves on a wedding day can fully grasp what that covenant will mean or what life will throw their way. We all hear “for better, for richer, in good times, in health” and breeze over the second half of each couplet: the wise and cautious reminders of the sufferings this calling will inevitably encounter.

Yet whenever I’m tempted to run the risk of clucking condescension for the fresh-faced kids standing on the altar, I remember this: we, too, had no idea what was ahead of us. But we, too, knew just enough for that day.

This weekend’s was one of those weddings when everyone agrees – over glasses of Chardonnay and cocktail hour Sinatra and children shedding suit coats underfoot – that They’re A Perfect Match, that We Couldn’t Be Happier For Them.

We nod and affirm, without ever saying it, that they do know enough for today.

And that the rest of us – jostling babies on the edge of the dance floor, leaning over linen tablecloths to hear grandparents tell stories, clinking forks against glasses to embarrass the newlyweds into a kiss – we are still slowly learning our way into our vows, too.
