Yes, I was thinking about the huge land and riches of the CofE (of course stolen from the Catholics by Henry the VIII - probably was a lot more important to him than Miss Boleyn)- and the Catholic Church is supported by the Vatican I suppose.
But when I lived in the UK, our local Vicars always said what a struggle it always was to find the finances to run their Parish. And just like here, the decision was made to seel the huge 18C Vicarage to release money- and a more modest home bought for the Vicar.
The Reformed Church here came about in the 1530 (our house, the Vicarage was built in 1587 - previously the Protestant Vicars were in digs in the village. And of course, as in Germany, the Protestant Church rose from nothing, owned nothing, no land, no riches, no housing- and was supported by the congregation and later the State. Our area was 90+ Protestant when I was a child- nowadays, Chruch goers are split 50/50 more or less- with an ever increasing % who do not belong to either Church or who have declared themselves non-believers (to avoid the tax).
In our Valley, 3 of 11 Vicarages have been sold- and number of Vicars cut by 50%- and they move the service from village to village. Our Church has a service about once every 3 months or so- and is therefore becoming a huge drain on the stretched Council budget (and tax payers' money- most of whom do not go to Chruch- but do use it for wedding and funerals).
