As a business, any religion should pay tax. Churches are not charities. If they were they would not be able to discriminate over beneficiaries with respect to religion. Catholic schools expect pupils to be catholic, for example. Ergo, not a charity.
Unfortunately, if we want to give the CoE a tax free status then the laws dictate same rules for all the other heathans and devil worshippers. After careful consideration, I say, ****** the lot of them. All religions are cults, and many of them have an 'n' in place of the 'l'. Let them ALL pay tax!
Businesses are taxed on their profits. So, how much profit did the CofE make last year?
