"The Rebirth of Orthodoxy" (Thomas C. Oden) - I liked this book, but it was very slow to read. It doesn't read like a novel, and I think it could be reorganized. That said, it makes a lot of interesting statements and has a lot of insight.
Oden believes the "postmodern" movement is actually the death throes of "modernism". Oden classifies the modern age as 1789 to 1989 (Bastille to Berlin). Modern thought started with a great deal of optimism. It was believed rational thought and logic could eliminate all of mankind's problems. The whole history of modernism can be seen in science fiction (which barely existed before the twentieth century). Starting very optimistic, even utopian, then proceeding to more pessimistic and directionless forms. That is postmodernism. The idea that everyone can believe anything they want, and everyone is right. This idea is attractive to many, but is leading a lot of people to look for more.
Oden differentiates Orthodoxy (capital O, like the Eastern Orthodox Church) from orthodoxy (small o), which is what is being reborn. This is seen in churches returning to Biblical foundations, and increasing willingness for churches to take a stand on fundamental differences (for example the Pope reaffirming that the RCC is the only true church).
There is a fair amount here, that I will probably return to later.
