Franny and Zooey is hardly less foul-mouthed than Catcher, yet it's filled with a more mature discontent. I would call it a religious book; it is certainly about the seeking and the inherently judgmental and egotistical pursuit that is the spiritual life, or rather what begins to build the foundation of the spiritual life. Did Jesus lack such discontent? Buddha certainly didn't. He walked out on his family, starting a seven year quest that ended with him sitting under his tree until he gained enlightenment OR his bones scattered. What but discontent could lead to such a decision? And the teaching starts with, Life is suffering (unsatisfactoriness). I think of Jesus sending tables flying through the temple. And yet, this journey ends with him silently accepting all. Kabir: "How humble is God? I wept when I knew..."
So Franny and Zooey is far truer a testament to the spiritual quest, as I have experienced it than any I am told in popular culture or the churches. Jesus came to baptize with fire. He's wielding a god damned ax. I use that profanity and blasphemy with all the angst and frustration I've known since I was a young boy dreaming of fighting with God. And do you know what? I no longer fear the punishment of a wrathful God for using it. Do you know why? Because He placed me into this paradox. He put these desires within me. He gave me the knowledge and judgment to question teachings about Him, until there is only a silent quivering. What sort of God could place me into such straits and then hypocritically punish me for the effects He caused?
Some would talk to me about agency, free will, damnation, salvation... But as I begin to see God as I was taught to see Him - the immutable, the I AM, the omnipresent - there is little room for a mistake in creation. Semantic arguments offer profuse explanation of the possibility of damnation in our small little world. But in such a small world, musn't damnation be proportionately small? If Jesus took on the sins of the world and suffered three days, how minuscule must my be judgment be? If He made me, then my works are His.
"Concerning the Gods, there are those who deny the very existence of the Godhead; others say that it exists, but neither bestirs nor concerns itself nor has forethought for anything. A third party attribute to it existence and forethought, but only for great and heavenly matters, not for anything that is on earth. A fourth party admit things on earth as well as heaven, but only in general, and not with respect to each individual. A fifth, of whom were Ulysses and Socrates, are those that cry: 'I move not without Thy knowledge.'" -Epictetus
