Jacob Weisberg, editor of Slate, writes about George W. Bush’s faith in his book The Bush Tragedy:
His religion has often been best described as evangelical, but in various respects it appears not to conform to the definition.

He didn’t try to convert others—one of the central obligations in most evangelical denominations—even before he resumed a political career. He didn’t raise his daughters in his faith. On issues that divide evangelical Christians from nonevangelical Christians—and varieties of evangelicals from each other—Bush does not need to feign ecumenical neutrality. He isn’t hiding his beliefs; he simply doesn’t have many of them.
A better term for Bush’s faith is Self-Help Methodism.
