Catholics, can you describe the beliefs and teachings of Catholicism in a down to earth way? I'm interested.?

I think the article "Pillar of Fire, Pillar of Truth" - a href="http://www.catholic.com/library/pillar.asp" rel="nofollow"http://www.catholic.com/library/pillar.a…/a is a pretty down-to-earth basic overview of Catholicism.
