Frederick Buechner, 76, is a Presbyterian, but he attends an Episcopal church. He’s ordained, but he’s never been a parish minister. His first book (A Long Day’s Dying) was not supposed to sell many copies, but it turned out to be the only best seller of the 32 books he’s published. In fact, this novel held such promise that some predicted he would become the next Henry James. Instead, he’s carved out his own unusual literary niche, including memoirs, theological writings and fiction, developing a loyal following along the way.
