Lately, I've been wondering: if Jesus arrived in Sydney via a time-travelling spaceship, and I was his tour guide, how would I explain our school system?

''Well, Jesus, you'll be pleased to know that many of our schools are what we call 'religious schools' based on the principles taught by you and your father,'' I'd say.

''Who goes to these schools?'' Jesus might ask.

''Only those who can afford the high fees - and a few who can't but are gifted in some way.''
