The Contemporary In The Cosmic III

In Operation Luna, Poul Anderson describes the York that we know (see York Minster) even though this, otherwise indistinguishable, York is on an alternative Earth where:

magic works;

air travel is by broomsticks or flying carpets;

the two American visitors are a werewolf and a witch whose daughter will later meet Prince Rupert of the Rhine and Holger Danske while traveling between universes;

the Devil/the Adversary is a real and active being;

Hell is a low entropy universe with distorted space-time;

there is contact with Heaven and a route to Yggdrasil;

evil supernatural beings have emigrated to the Moon;

an enchanted sword speaks;

etc.

Can our York coexist with all that? Many who have lived there have believed in at least some of these things.
