There have been two interesting articles recently about faith in fiction. The first one, by Paul Elie in The New York Times, raises lots of questions and draws attention to a few books that are certainly worth reading.
The second, which is also fascinating, is a response by Gregory Wolfe in The Wall Street Journal.
Though both authors make valuable points, they also both focus on Anglophone (and mainly American) literature. That's fine up to a point but, I would argue, the picture looks very different if you widen the lens: Torgny Lindgren, Kyung Sook-Shin, Roger Bichelberger, Fan Wen, Uwem Akpan, Martin Mosebach ...
And that's just a few of the Catholics.
