According to gossip-site Popbitch, Philip Pullman’s son got married last weekend in a full Catholic wedding ceremony. The words of Popbitch:

Wedding day bliss for Pullman

Philip Pullman may be one of our foremost
atheists but his son got married at the weekend
in a Catholic church with full mass, a choir
and a soloist who sang Ave Maria. Pullman even
gave a reading from Corinthians ending “God
is love”, to one or two raised eyebrows. He
didn’t, however, take communion.
