I just read this in today's Times...
It seems the Universal Church of the Kingdom of God, which occupies the old Astoria/Rainbow building in Finsbury Park, is encouraging its congregation not to pay their personal bills so that they will have more money to give to 'God'.
UCKG say that only when people sacrifice all their worldly possessions will their financial prayers be answered. They even offer financial 'help' with this.
It saddens and angers me that this sort of thing is still going on, and less than a mile from my front door.
Read the articles here, though you have to subscribe to the Times site (I will attempt to upgrade this in due course). And here's a 'review' of the church.
