Tolkien and Lewis are two of my favorite writers as well. Pullman often speaks out about how much he dislikes Lewis' narnia books, he is even called by some the "anti-Lewis". If you were to read all the way through Golden Compass, you might not find anything too objectional, it isn't until further in the second book that hints start coming, you might even be able to read all of book two without finding anything objectional, but book three goes all out. It has a lot of very New Age ideas in it, but the premise it basically war against heaven, and the people and gay angels play the part of the rag tag rebels and God's second in command, Enoch, leads the army of heaven against the rebellion, but only because God is to old and decrepid to do it himself. By the end of the third book the protagonist, the little girl, kills God.
