When Pokémon Go first appeared, many Christians were optimistic about where it might lead.

The game was “a great opportunity” to reach out to non-churchgoers, said the Church of England, which suggested parishes might offer players drinks and snacks and recharge their phone batteries.

“#PokemonGO is drawing people to churches,” tweeted Bishop David Ricken of Green Bay. “Great! What an excellent opportunity to share the love and mercy of Jesus in this Year of Mercy!”

But the designation of churches as PokéStops – sites where players can collect virtual items and catch Pokémon creatures – has not always worked out as anticipated.
