Cartooning by committee

Any thoughts you can give me on the following subjects would be most appreciated and would help me to remain sane. Don’t worry if the ideas are stupid or not funny – really – anything helps.

Christingles: What do they mean? Who makes them? What sort of mishaps happen at Christingle services? [Cartoon now drawn – thank you!]
‘Fresh Expressions’: What are they? What odd or unusual ones have you heard about? What would the ideal ‘fresh expression’ be?
Curates: What do they do? Which jobs do they always get given? How can you recognise one?
Bishops: What do they do?

Thanks in advance for your assistance. Seriously – it helps.
