There aren't enough priests and many churches are in completely the wrong locations to support a congretation. A lot of quaint churches are expensive to maintain.
I feel that some really quaint churches in villages could be made into wedding venues rather than parish churches. I would like to see a situation where anyone can choose to get married at the really pretty church in the lake district with no working congretation.
Even in towns there are too many churches in a short distance. I feel that existing buildings could be used in more imaginative ways that would support the entire community.
