Tycho: The "assumptions" I made were only in things that are essential to salvation and thus necessary to argue the rest of the points (i.e., the premises). If God doesn't exist, then none of the other stuff matters...period.
Yes, exactly. The key, though, is that we don't
know whether God exists. It's an open question that people need to reach some conclusion on in order to even worry about the salvation stuff. So anything that makes a person doubt that God exists is a "salvation" issue, because it may cause them to abandon the stuff that is essential for salvation if God is real.
Heath:
What happens if some of the non-essential facts are not true? SHOULD (and I keep emphasizing the word SHOULD) a person lose faith if non-essential facts are simply errors, mistranslations, or figurative speech? I doubt it.
I think there are two issues that are tripping us up here:
1. You're focussing exclusively on "non-essenial" that are "simply errors, mistranslations, or figurative speech." I think we can largely agree on those. The question is about out-and-out lies? I know you don't feel someone making up a story about conversations with angels qualifies as a lie, but many others do. We might not get much further on changing each others mind about the specific example, but it would be useful to at least hear your position on cases if they really were straight-up lies. Then we'd at least be at the point where we could both say "okay, we disagree that this is a lie, but if someone changed our mind on that, we could agree with the rest of what the other person says." So, if there were intentional deceptions (not just honest mistakes or mistranslations, etc) in the bible related to Jesus' miracles, would you agree that it would be rational for a person to doubt other claims it makes??
2. I think the word "should" is being used in two different ways here. I think you're using it in the "given that we believe God exists and that faith is the key to salvation, will they be better off making this decision?" sense. And under those assumptions, the answer is indeed that they should keep the faith. But I'm using "should" in the sense of meaning "is this the best decision given the limited information they have available to them?" Does that sound about right? You're talking about the costs/benefits of a decision, whereas I'm talking about making a decision based on limited evidence? I think we're getting tripped up on this because you're saying they "should" keep on believing as they do (because that belief is critical for getting into heaven), whereas I'm saying they "should" change their minds (because they no longer have good evidence that heaven actually exists). We're both using the same word ("should"), but meaning slightly different things by it. We seem to be talking about different aspects of the question, with me focussed on making a rational decision with limited data, and you focussed on obtaining salvation.
Heath:
So then the only question is whether I could survive the test of faith. That question is completely separate and apart from the factual statements you make. So, yes, those facts are irrelevant.
But IF you didn't "survive" your test of faith, wouldn't your actions change? Would you still make covenants with a God if you didn't believe He existed?
Heath:
Wrong facts that are not essential are like tree branches that have grown at a bad angle. You simply cut them off and the tree lives on. If the fact is critical to salvation, it is like a disease in the roots or trunk. You then would have to cut down the whole tree. If you cut down the whole tree because one small branch was diseased, that wouldn't make any sense to me. The same is true of religions.
I think this is a fundamental difference in how you view the question of religion and how I (and possibly katisara) do. I tend to ask "do I have good reason to believe that the supernatural claims of this religion are true? Does its afterlife actually exist? Will following their instructions actually lead me to that afterlife, etc?" The very first thing is to figure out if I believe it or not. So anything that calls into doubt the credibility of those making claims about the religion is a pretty big deal. Because if someone lies to me about the little stuff, I'm not going to believe their claims about the big stuff.
In your analogy, all I can see are the branches of the tree (or, perhaps just the leaves), and someone is telling me about how great the leaves are because the trunk is so great. I can't actually see the trunk myself, I just have to listen to this person's stories about this amazing trunk, and look at the leaves. But if I see that the leaves are diseased, and not at all like what the person told me the leaves were like, I'm really not going to believe them when they tell me that the trunk is great. It's not that I'm saying "an amazing trunk is fine, but I won't take an amazing trunk with bad leaves!" Rather, I'm saying, "this guy lied about the leaves, he's probably lying about the trunk too. I'm guessing it's diseased all the way down to the roots based on what I can see."
On the other hand, you seem to be taking the trunk as given. In your analogy you can see the whole tree, from roots to trunk, to branch, to leaves. You feel like you've inspected the trunk, and know that it's sound. So you can prune a few bad branches and still not be worried about the overall health of the tree.
Basically, you consider the whole tree to be "visible," where I consider the majority of the tree to be hidden from sight. How one reacts to bad leaves in those two cases would be different.
