When young, I put "C of E" on application forms where the unwanted question, your religion?, was asked (e.g. University application form).
Nobody asked what it meant. To me, C of E meant "Critic of the Establishment", not Church of England.
Any other ideas regarding alternative meaning possibilities that involve religion? Invent if necessary
Who's asking? I might consider putting "N/A." Perhaps "Recovered Catholic."
I'd be wary of why anybody would need to know, but if for census-type reasons, would be happy to put "Atheist."
Continuity of Evolution?
On any form that asks your religion write down "recovering."
Would this get me a free light sabre? Because I'd totally go for a religion with benefits.
