I joined the ULC myself. They seem to keep themselves going by selling 'prayer kits', 'reverend on call' badges for your car (I suppose so that you are less likely to get a ticket for parking illegally), and other slightly dubious parephenalia.
However, I rather like their credos, embodying as it does the two concepts of 'good' and 'not getting into trouble':
'You should do what you feel is right, as long as it is not against the law'
As far as I can tell this is their only 'commandment'. As religions go, they get maximum points for being concise.
