Our president embodies [America's] uncentered spiritual landscape in three ways. First, like a growing share of Americans (44 percent), President Obama changed his religion as an adult, joining Chicago’s Trinity United Church of Christ in his 20s after a conversion experience brought him out of agnosticism into faith. Second, he was converted by a pastor, the Rev. Jeremiah Wright, whose highly politicized theology was self-consciously at odds with much of historic Christian practice and belief. Finally, since breaking with that pastor, Obama has become a believer without a denomination or a church, which makes him part of one of the country’s fastest-growing religious groups — what the Barna Group calls the “unchurched Christian” bloc, consisting of Americans who accept some tenets of Christian faith without participating in any specific religious community.
