I don't think it would have any implication whatsoever.
Goedel's theorems are simply theorems about formal systems which contain arithmetic.
Why would a formal system containing arithmetic ever have any effect on one's understanding of God?
A man made religion is not dissimilar to a formal system. Bear with me here. I have a degree in math and some graduate level math experience so I understand rigor. Look a philosophical system has to have undefinable terms, it has to have something like axioms, and it has to have rules that are more less strongly enforced when one tries to apply it to life or cosmology or whatever.
Here might be axioms for Biblical faith (knowing that true faith is deeper than this but I'm just saying)
Axioms
1) God exists
2) There is One God
3) God is Good
4) God is Omnipotent
5) God is Omniscient
6) God is Omnipresent
Each of these has the undefined term God in them, and all of the descriptive words can be at least qualified.
Taken together with some descent qualifiers for the terms, love, omnipotent, omnipresent, omniscient, person, exists we have a 'definition' of God.
Now notice that if my faith were simply a human exercise I could construct an entire religion from those 'axioms' and say things like,
because God is good He will not hurt me
It is a weak theorem of sorts that may or may not be true in reality but depending on how I interpret 'good' I may believe this.
I am not submitting that Christians should pursue God this way, but that rather those who do not know God often do. Their faith is not trust in a person they know, rather it is mental assent, based upon a set of a priori beliefs that continue to make sense perhaps only becuase they have never been contradicted.
Other religions then we simply alter axiom 2 from There is One God to
The most general set of axioms, maybe pseudo-axiom is better because in modern math we have completely divorced ourselves from the close ties to philosophy that men like Liebnitz enjoyed. We can protect our backs by agreeing we aren't really trying to involve mathematics here.
What the development it is straight forward.
A1) There is no god.[atheism]
It matters not what the definition for a 'god' is. it simply is true or is not true as a statement about a term that does not need to be defined.
B1) There exists at least one god [agnosticism?]
Again, now maybe we need more axioms
D1) there exists many gods [pantheism]
E1) there exists one God (God is One) [monotheism]
E2) God is Triune [christian monotheism]
What I am saying is that comparative religion is at it's heart axiomatic since at some point those who think about religion must accept some statement as true without knowing it is true. This is not faith in the Biblical sense of the greek word
pistis. It is a very human assumption.
There is no reason to believe that human perspectives on society, life, right and wrong, the afterworld, love, war, peace etc. are not all ultimately based upon lists of axioms, with many undefined terms, and some rules of logic that they use to argue for things, to reason or divine our way though life.
I believe that Christiniaty differs in that one knows God, that would be the phrase 'you must be born again.' But some would argue that is an evangelical creation not to be taken seriously. I would beg to differ but would not try to force that since how could you.
Now the rules of logic that people use, we have to fuzzy that up to understand the rules they use.
Mathematicians like to use If/then statements to get everywhere. If this is true then do this unless this and then do this, but why? The why references back to supposedly deeper motivations and supporting arguments, 'I want to', 'God told me to', 'I feel like it', 'It will help someone I love.'
So motivation is part of it all too.
How often has you heard someone say this.
'Why did you did'nt you do this or that?'
'It just does'nt make sense to do that.'
Anyways, I am laying all this out there in the spirit of discussion so I will wait and see what you guys come up with.
I would say that I agree that in order to even consider this we have to fuzzy up our notions of definition, undefined, rules of logic and broaden them to include all human experience, that said we can investigate alot of things this way.
For instance consider this tenet of the Christian faith
C56) God is good
What if God is not good? What if what God does does not seem good to us? What if we do not know what good means? Is good in God's mind exactly the same as good in our mind? Why or why not?
It has long been accepted that the basic threefold purpose of the church is worship, fellowship, and discipleship.
In the matter of discipleship Isaiah said
'My people perish for lack of knowledge.' chapter 5
'Order on order, order on order,
Line on line, line on line,
A little here, a little there.' 28:9
As mathematicians we do have definitions that allow several things here. We can register ageement or disgreement on particular points of doctrine between denominations or philosophies and then create a distance measure. a weighted graph, trees that show relationships.
That is all sort of geek stuff I guess, but some people fear the application of statistics and structural modeling to society, and I think rightly so to some extent.
But when God says 'My people perish for lack of knowldge.' if we hold the Bible to be authoritative we have to wonder what that means.
Not every pursuit of knowledge is right in God's eyes, and I would not dare reverse the stakes and turn God into a lab rat. What I would say is that exhaustive resources documenting the differences between belief systems in a variety of ways might aid in peoples understanding of the issues we all face.
I think if we consider it carefully there are areas of everyone's life where we use terms for which we have no definition, or for which the definition we have leads only to more questions.
Imagine a website where I can learn about Christianity. I choose to look at the question of Trinitarian churches so I click under issue and choose trinity, immediately a rich mutimedia page comes up with links to lists of Trinitarian and non-Trinitarian churches, videos, history, important persons, etc.
What if we were studying a history of schism in the church and presented it as a graphic, a zoomable tree where each node had a link to complete background on the issue, the dates and the persons, the politics?
I realize that is a lot of sort of scattered ideas, but I get excited about this. How many Christians would have closer fellowship with others if they could understand how their church is like or different from the one next to them?
That's enough.
A simple distance between to faith's determined by agreement/disagreement on major points of doctrine might be interesting. A cluster analysis of survey responses related to social issues where the identifying flag was denominational affiliation, we would want to test for spatial variation as well.
For a believer what would the point be? The point is knowledge is a tool in the hands of a master builder. Paul used his knowledge to build the early church, the more knowledge have to day of the world in which we live the more effective we can potentially be, the more shrewd in our arguments and actions.
So here is a challenge of sorts.
Define the term 'God.' Give justification if you can.
