As if religious charity has always been financed by the state.
Actually it has always been funded in part by the state - via the tax breaks linked to charitable status.
And before you say that this applies to all charities equally - it doesn't. Religious organisations benefit from a number of special privileges in terms of charitable status compared to other charities. The first being that a religious organisation needs to claim nothing other than being a religious organisation to be a charity - they do not need to demonstrate one iota of broader community benefit. Compare that to, for example, private schools that need to demonstrate engagement with the community beyond the school to gain charitable status.
In addition, many small churches can benefit from charitable status without actually having to register as a charity. The income threshold for them is massively higher than for non religious organisations. So a secular youth club with an annual income of £20k would have to register as a charity with all the bureaucracy and process involved. A church with exactly the same annual income wouldn't have to register at all, but would be given the same charitable benefits.
Third - business rates - religious buildings are completely exempt from business rates, so you won't even be able to find them on the VOA list - by contrast other charitable organisation have to pay business rates on the premises - albeit with a reduction as they are a charity, but that reduction never takes their business rates to zero, unlike the churches.
