Brave New World Test Prep

Eh I know I'm probably the only loser coming on today, but just thought I'd ask a few questions and/or comments about Brave New World before our test tomorrow. Does anyone FULLY understand the religous conversation between John, Bernard, and Mond in Chapter 17? I understand some parts of it including: God being labeled as "old" and so he must being forgotten...but does anyone get the quotes by Cardinal Newman and what Mond believes is the way people develop a belief in God? Mond's big thing is that alot of things he doesn't want in his society aren't wanted because he's afraid that those things in the end will make the society more unstable. And a comment on Violent Passion Surrogate (VPS) seems to me to be a complete opposite to soma, it seems to give you the equivalent of fear and rage without having to go through the actual situation...why would this even be needed?
