All art is religious

Jed Perl on Rouault and Chagall. Perl is a good critic, but the way in which he thinks he needs to convince his readers that modern art and religion are compatible is just funny. It shows that our intellectual elites really have no clue on the nature of religiosity,i.e. on the nature of reason. The results, of course, is that everything becomes a fragment separated from the whole, left in the care of some "experts." Like art, which is what artists do and what art critics discuss. Why should it be related to religion?
