Ouch! This is heart breaking, Kev.
I always have a vicar or similar person in my books, a sort of central person who can drop in wise words when they're needed. A bit like G.K. Chesterton's Father Brown stories. In the current one that I am writing, the poor young vicar, just starting out, has only a handful in his congregation. He starts welcoming newcomers to the neighbourhood and little by little the congregation increases. The heroine, a non churchgoer, finds herself in need of something only he can do.
I've made it so that it could be a Baptist, Methodist, Anglican, or similar sort of church.
Maybe by now, Kev, the congregation will have increased. Hope so, because the church represents so many cultural values as well as the spiritual ones.
