Ask a theologian

Had a (small) older youth cell group tonight which was 'ask a theologian (i.e. me) any question you want'.

The questions (in no particular order):
Should we believe in aliens?
Should I go out drinking with my mates?
What is a 'doctrine'?
What about the dinosaurs?
What about the stuff Jesus said about adultery and divorce?
Why is the Old Testament about Israel and the Israelites?
How literally should we believe the Bible?
Should you be baptised before you take communion (because in another church they won't let you take communion unless you've been baptised)?
Why did people live to ridiculously old ages in the Bible?

Afterwards the general consensus was 'this was good - let's do it again'.
