Marilynne Robinson's Gilead (I still haven't read it) won the 2005 Pulitzer Prize for Fiction.
"This is a quiet book," she said Monday from the porch of her home. "A lot of young writers think they have to write something sensationalistic to get noticed. I'm very pleased that this book, which is very theological in many ways, seems to be interesting to a lot of people."
Robinson is also the author of the book, "The Death of Adam," which, among other things, argues that John Calvin is highly under-read:
"In several of the essays in this book I talk about John Calvin, a figure of the greatest historical consequence, especially for our culture, who is more or less entirely unread. Learned-looking books on subjects to which he is entirely germane typically do not include a single work of his immense corpus in their bibliographies, nor indicate in their allusions to him a better knowledge than folklore can provide of what he thought and said. I have encountered an odd sort of social pressure as often as I have mentioned him. One does not read Calvin. One does not think of reading him. The prohibition is more absolute than it ever was against Marx, who always had the glamour of the subversive or the forbidden about him. Calvin seems to be neglected on principle."
