That’s how Joshua Rothman pegs U2 in an essay exploring the faith behind their music:
In some ways, this seems obvious: a song on one recent album was called “Yahweh,” and where else would the streets have no name? But even critics and fans who say that they know about U2’s Christianity often underestimate how important it is to the band’s music, and to the U2 phenomenon. The result has been a divide that’s unusual in pop culture. While secular listeners tend to think of U2’s religiosity as preachy window dressing, religious listeners see faith as central to the band’s identity. To some people, Bono’s lyrics are treacly platitudes, verging on nonsense; to others, they’re thoughtful, searching, and profound meditations on faith.
Christianity Today regularly covers U2, not just as another Christian rock band but as one of special significance. In 2004, the magazine ran an article about Bono’s “thin ecclesiology”—his unwillingness to affiliate himself with a church—that sparked a debate about the health of organized religion. Rowan Williams, the Archbishop of Canterbury at the time, addressed the issue of Bono’s belief in a fascinating 2008 lecture about the place of organized faith in secular society. “Get Up Off Your Knees: Preaching the U2 Catalog” is one of several books exploring the theological ideas in Bono’s lyrics. Churches around the world have held “U2charists”—full services at which traditional church music is replaced with songs by U2. A few years ago, an Episcopal priest I know helped organize one at a church in New Jersey; the service, which featured a huge sound system, stage lighting, cocktails, and a bonfire, raised around forty thousand dollars for an orphanage in Cameroon.
