Abstract notions and Propositions
Generally if we refer to propositions, we are speaking of a statement that can potentially hold a "truth" value. If I state the proposition, "Gold is in China", this can demonstrably be proven "True" or "False"; the predicate can be affirmed or denied. However, "God is in China", to some philosophers, would not be considered a proposition as the subject does not allow
the predicate to affirm or deny. Why does the subject not allow the predicate to be affirmed or denied? Because the subject, "God", is an abstract notion. Abstract notions do not exist in any defined time or space, they are only ideas, abstractions. "Justice", "Country", "Government" are all examples of abstract notions.It's very important we note this if we are to attempt to make truth-statements containing "God"
-- we'll be on a slippery slope fast if we don't watch ourselves.
Belief and Knowledge
One has the capacity to
believe without
knowledge. In terms of your gold analogy, I could
believe there is gold in China, without any empirical knowledge. I can just as easily believe my friend is in the kitchen, even though he may have just entered his bedroom. The term "Belief" is
very varied in it's usage, and there is a
range of intensity with which it can be spoken. Two sentences such as, "I believe it's snowing outside", and "I believe 2+2=4", can carry different ranges of intensity and meaning. That is, you might "Not be so sure" it's snowing outside, but "You're really, really sure" 2+2=4. Some may use "I believe" interchangeably with "I think", and some may use "I believe" interchangeably with "I know", indicating a 'stronger' belief.
Semantic variance
"Gold" is a term we've dubbed to classify a certain type of metal, a metal we have categorized in our periodic table of elements. There is an intersubjective (for all practical argument, it's universal) understanding of not only the
usage of the word, but
its meaning. Some abstract notions, however, such as "God", vary immensely in their
usage and
meaning. To even
begin a philosophical debate concerning this word, we would have to agree upon conditions with which the word applies, in addition to clarifying (the best we can) the meaning and usage we're referring. Otherwise,
language will not bring clarity to the discussion, and no intelligent debate can be had. It would be like arguing viciously what flavor of ice cream is the best.
God as experience
Many spiritualists note "God" is to be experienced, not studied. Any use of language in attempting to describe this word evokes the ancient Buddhist saying, "Don't mistake the finger pointing at the moon for the moon". An important note to those that seek "Proof": You will only find "Proof" within your own experience - don't look for it elsewhere.
Summation
With the understanding "God" is an abstract notion and has the potential to be believed:
I'm not a theist because I know humans have the capacity to believe there is no God; I know the notion can sometimes not exist. I'm not an atheist because I know humans have the capacity to believe there is a God; I know the notion can sometimes exist. I'm not an agnostic in regards to theism because I know both of these classifications can exist and the abstract notion believed depending on the consciousness rationalizing.
Remember, folks, this doesn't mean I'm not spiritual:
"God" only means what I dictate it to mean. One can experience spirituality without succumbing to linguistic confusion. It's utterly pointless to argue about "God", just as it's silly to argue about "Redness". Remember to ask yourself:
Am I clarifying or muddying the subject with which I'm speaking? Language can sure turn into a bloody mess if we aren't careful.
