Christian faith still making positive waves in the world

In an increasingly secular time, it’s easy to diminish Christmas 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.

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, and honorably so) 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 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.

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 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 Leviticus said about homosexuality and stress narratives of personal salvation (see those John 3:16 signs at football games).

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.

Matthew’s gospel reminds us of these words from Jesus: “You have heard that it was said, ‘You shall love your neighbor and hate your enemy.’ But I say to you, love your enemies and pray for those who persecute you, that you may be children of your heavenly Father.”

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.

In his book “Simply Christian,” N.T. Wright, the former Anglican bishop of Durham, urges us to remember martyrs such as Dietrich Bonhoeffer, the theologian killed by the Nazis; Archbishop Oscar Romero, shot in El Salvador because of he spoke out on behalf of the poor; and, of course, Martin Luther King Jr. “They are a reminder,” Wright wrote, “that the Christian faith still makes waves in the world, and that people are prepared to risk their lives out of the passion for justice which it sustains.”

Earlier this month, one of my theological heroes, Father Johann Baptist Metz, died at the age of 91. Metz insisted that “the salvation to which Christian hope is related is not simply or primarily the salvation of the individual ... but as salvation of the covenant, of the people, of the many.”

If this were not true, I’m not sure Christianity would have flourished and survived into our time. At Christmas, we remember a child, but even more, we remember the sweeping hope his birth inspired.
