Hi Coolmummy. Maybe where you are in the UK it's not funded with tax money, but here in the States, Catholic Charities are most definitely funded or subsidized by a state.
For three years, St. Anthony has been operated by Ramsey County, St. Paul, the state of Minnesota and Catholic Charities, at a cost of $18,000 per person per year. It's one of four so-called "wet houses" in the state.
