A reason to remember what Christianity should be about

Christmas ought to remind us what the whole thing is about.

By the “whole thing,” I mean Christianity, the enduring demands of Jesus, and the remarkable fact that 2,000 years later, so many are still captivated by the birth of a baby in a stable.

In an increasingly secular time, it’s easy to diminish this holiday as a repurposed pagan celebration bathed in sentiment and commercialism. And I won’t pretend to be immune from the season’s sometimes syrupy sweetness.

I love seeing cars race down streets with Christmas trees tied to their roofs. I never tire of reruns of “It’s a Wonderful Life” — or, for that matter, Frosty and Rudolph. A regiment of nutcrackers musters every year in our front hall while a nativity scene in our living room reminds us of the family that couldn’t find room at the inn.

But in the United States, we live in a moment when Christianity is losing ground, especially among the young. I speak not of demographic change (our country is more religiously diverse than ever) but of outright abandonment.

Americans under 40 are the least religiously engaged generation since we have been measuring such things. They are skeptical of organized religion, and many in their ranks see Christianity as hopelessly complicit with political figures they perceive as reactionary, authoritarian and intolerant.

Many Christians counter by pointing to voices that have been raised loudly on behalf of immigrants and refugees, the marginalized and the impoverished. (See, for example, Pope Francis.) But this speaks to the challenge Christianity faces: It stands before the world deeply divided. Its trumpet, in St. Paul’s metaphor, is giving an uncertain sound.

In one sense, there is nothing new here. Christians, like members of other faith traditions, have disagreed about worldly matters for centuries. Religion, as the conservative thinker Irving Kristol shrewdly observed, can be both prophetic and rabbinic — on the one side, in revolt against things-asthey-are; on the other, insistent on observing the laws embedded in tradition.

You see this divide when progressive Christians, who cite the liberating Exodus story and the Sermon on the Mount’s personal and social demands, face off against conservative Christians who point to what Lexviticus said about homosexuality and stress narratives of personal salvation. It’s no accident the Gospel’s affirmations about the poor and the marginalized — along with Exodus and the prophets Micah, Amos and Isaiah — tend to be heard more often in African American churches than in conservative white congregations.

The skeptic would take all this as proof that religious faith, including Christianity, is a human invention that individuals and groups turn to their own worldly purposes. And Christians of all stripes often make the skeptics’ point by behaving in thoroughly un-Christian ways, perhaps especially in their arguments with each other.

There isn’t a lot of that “love your enemies” thing going around, and I confess to finding it difficult myself these days.

But in the spirit of fellowship, I’d suggest that anyone who thinks of themselves as Christian must see this faith as something more than a venerable, comforting tradition — or as a ticket to heaven.

At Christmas, we remembered a child, but even more, we remembered the sweeping hope his birth inspired.
