I remember one of my neighbours raving and ranting about some of the Churches being turned into Sikh Temples, a Chinese Church, even a wonderful Jain Temple- and my answer was- if the Christians have abandonned these bulidings because they don't go- would you prefer them to be demolished. And he said yes, at least the demise of the Christians Churches would nto be so obvious, and it would stop the other ***s from using them.
Our village here only has 700 people- we are struggling to keep the budget afloat, and our Council taxes are very high. The Council has to maintain and heat (the heating system is on its last legs) both our lovely 14C Protestant Church (taken over from the Catholics at the Reformation with out local Reformer, Farel, in 1530s) and also the Catholic Chapel, built by Polish refugees of war. The Protestant Church is used about 10 times a year max, a service from time to time, funerals and a few weddings. Almost all the Catholics in the area (like my dad) have now died- and the few that remain go to the services down in the big village in the Valley.
Our generation will continue to maintain them out of respect, even if very few go to Church- but I can well imagine that the next generation will say- we need money for schools, health and leisure/culture- we do not have enough money in the pot- something has to go- and the Church and Chapel will probably be top of the list as so few use them.
