Katisara did a good job of responding to this, so this reply may be unnecessary. But just in case...
Heath:
What I am saying is not to say something is a foundation if it is not.
What do you start with? You start with the principles essential to salvation.
And what I'm saying, is that that's a horrible place to start! You don't accept the conclusion as a fact first, and then pick and choose the premises will get you there. You start with the data you trust, and then work your way up to the conclusions. Your way of doing it seems to put it backwards to me. You've picked what you want to believe, and only care about the facts that are absolutely necessary for it to be true. But that seems entirely the wrong way around to me.
Heath:
You don't start with historical facts. History books do not get you salvation, even if you believe in them cover to cover.
I disagree! You absolutely should start with the facts. Otherwise you can just pick whatever belief you want.
Heath:
Each little fact in the Bible is not "foundation." It is not "essential" to one's salvation. The Bible was not even written by God, but by men and prophets through the inspiration of God.
Agreed. But the bible itself is a foundation to some. Because it makes some huge claims. As the saying goes, extraordinary claims require extraordinary evidence. And they bible makes some extraordinary claims. If one accepts that some parts of it are mistaken (or worse, lies), it becomes very difficult to believe those extraordinary claims. If you've got a friend, Freddy the fibber, who's known to tell a tall tale, stretch the facts, and generally must make stuff up, and he comes to you and says "Heath, I've made a shocking discovery! Doing 50 jumping jacks each morning while singing 'Oh Canada!' is absolutely critical to your salvation! If you don't do it, you won't get into heaven!" The correct response is not believe him. You absolutely don't say "well, I know you've struggled with telling fibs in the past Freddy, but since this one is important to salvation, I guess I should just believe it!"
Hopefully that makes sense. So let's change the scenario a bit. Now you just have a friend, Freddy, who as far as you know is an honest, upstanding fellow who never tells a lie. Now he comes and tells you about the same "shocking discovery," and perhaps because you believe him to be so honest, you believe it. But the next day your other friend, Sally the sceptic tells you that Freddy has a long history of making up tall tales, playing pranks, and generally lying. She gives several examples of things he's claimed that have been proven to be false. Now, none of those things are directly related to the jumping jacks, and he's never claimed they were required for salvation before. Under what Doulos and I are saying, that new information should change your views, because it calls into question Freddy's reliablity as a source of information. But under what you're saying, you'd still go on believing him, since all that other stuff doesn't matter to your salvation. And that doesn't make sense to me.
Heath:
What you are implying here is that every single piece of data is critical to salvation.
No, what I'm saying is that every single piece of data tells you something about the reliability of the source of that data. If source X tells you something about salvation, one way to check to see if you should believe it, is by looking at all the factual stuff that X tells you, and testing to see if it has a good track record. If not, then X might not be a trustworthy source. Everything X says tells you something about how much you should trust X,
regardless of how important those things are to your daily life.
Heath:
I am saying you must separate the wheat from the chaff. Let new data form your opinions, but hold to the principles. Principles are eternal, while the historical facts may have differing interpretations, which is why you can't cling to them.
But again, you're starting with the
assumption that all the principles in the bible are correct, good, eternal, etc. I'm saying you need to reach that
conclusion based on other data, including the data you have on how reliable the bible is as a source of information.
Tycho:
Having faith that is robust to contradictory evidence isn't a feature, it's a bug!
Heath:
EXACTLY! That is why you should not vest all your faith into certain facts at all.
Erm...I think you completely misunderstood what I'm saying here...
Heath:
I am the one saying the principles are important, not the facts.
And Dolous and I are saying that if they can't get the facts right, why would you trust them to get the principles right?
Heath:
Under Doulos' argument: If any fact of the Bible is found to be not true, you must throw out the whole Bible and your entire belief system.
I don't think he'd go quite that far. More that if any fact of the bible is found to be not true, then that calls into question the reliability of the bible as a source of information. And since the "important stuff" requires you to put a huge amount of trust in the bible as a source of information, that may cause you to doubt it. You may believe
some parts of it still. No one is saying that if one part is wrong, all parts must necessarily be wrong. But we are saying that if a single piece is wrong, then it's harder to trust every other claim it makes. And since some of the claims take vast amounts of trust, even a little doubt may cause one to abandon the parts you'd call "the important" parts.
Heath:
Under my argument: If any fact of the Bible is found to be not true, the principles are still true and you don't throw it out. If it's not critical to your eternal salvation, don't cling religiously (pardon the pun) to facts just because they are written in a religious volume. And very, very few historical "facts" are necessary for salvation.
Again, you seem to be starting with an assumption about the truthfulness of the principles. I don't think that's a smart thing to do. You need to have a reason to believe that. Your approach seems backwards to me. You pick your desired conclusion, and then evaluate the importance of other claims based on that, rather than testing what you can, and evaluating the likelihood of the conclusion based on the results.
As Katisara said, what you're proposing seems designed to minimize the chance of changing your mind. And to me, that seems like the absolute worst thing to do. Your view seems to be that a "good" faith is one that is nearly impossible to disprove. Whereas I would say that it's much better if you believe something that has lots of ways to easily disprove it (if it's wrong), but none of them have turned out to do so. The more ways it could be disproven, the more trust you can put in it when it hasn't been disproven. Something that hasn't been disproven simply because it's largely untestable doesn't (or at least shouldn't!) give one much confidence.
