Atheists are more direct about the topic, perhaps?
Direct in using words that underly their beliefs about the relationship God has with the world, etc?
The use of the word "immanent" is understandable, if your particular brand of belief is that God is in the leaves and rocks, but that isn't a general requirement of theistic belief. And "transcendent" reflects the omnimax idea.
Your ideas about these words are somewhat erroneous, but at least you are correct in understanding that the terms underly a specific relationship with things of this world, etc.
The reasons that some theists shy away from the word "supernatural" are more interesting, I think. I can only speculate as to why they do that. One reason might be that they associate "supernatural" with lots of other ideas that they do not necessarily want to embrace or identify with.
So given that atheists tend to display a wholesale bias in using the word "supernatural", what specific advantage do you think they could also secure in lumping God in to a category that has lots of other ideas that have nothing to do with theism?
For example, a particular theist might believe in the idea of an immortal soul, but not believe in ghosts. Ghosts, being thought of as persons who are separate from nature are "bad supernatural", whereas God is "good supernatural", even though both concepts share many elements in common.
The theist might believe in "evil spirits" or "demons" or similar, that they regard as separate from God, and they might be happy to describe such beings as "supernatural".
There are theistic traditions that entertain the notion of ghosts and God. Your speculations about how this automatically grant them a similar or identical relationship with the world because they "appear similar" in your mind are simply speculations (probably fueled more by the influence of hollywood than any legitimate cultural or philosophical reference).
Another possibility is that theists, by their nature, tend to blur the lines between what can and cannot be verified.
You don't see people who subscribe to empirical world views also being completely susceptible to this also?
If the length and breadth of science is about systematically analyzing observations of the physical world, that is fine. If you want to take that a step further and say this also now spells the length and breadth of reality, you cannot do that without blurring the line.
That is, they actually maintain no firm demarcation in their heads between the "natural" and the "supernatural".
But you are the one introducing this (false) dichotomy.
Having recourse to special words that help you demarcate the stuff you believe is real from the stuff you believe is not real is certainly helpful .... but only insofar as assisting your world view. Establishing your world view as superior or philosophically cogent is a far more arduous task than merely saying, "Look, I just called that supernatural!"
For them, the world is populated by ethereal entities (often persons) of different types, and those entities are just as "real" to them as the rocks and leaves. If you hold such a worldview, the term "supernatural" becomes unnecessary. Your world consists not just of what can be verified empirically; it is also populated by fantasies whose reality you take as a given. Testing the assumptions is either discouraged or the idea to test the assumptions simply doesn't occur. Religions and their "scriptures" rarely pay any attention to the veracity of their own precepts; those are unspoken and taken entirely for granted.
So the notion of life being reducible to an arrangement of chemicals is supernatural?
After all, its certainly a claim that blurs the distinction between what has and hasn't been (empirically) verified.
Or do you feel its an unnecessary term because the "ethereal" existence of life is but part of the same integral existence of rocks and leaves?
As for atheists, a word like "transcendent" is a bit vague; "supernatural" seems more specific, and goes to the heart of a demarcation issue that atheists consider to be pivotal.
How do you figure it as vague since you have just mentioned earlier how "supernatural" encompasses a category of things that has nothing to do with God, or the role God is alluded (IYHO) to have within this world?
I'm speculating, but you can tell me why you don't like the word "supernatural", from the point of view of your own theism. So, over to you.
Because it has automatic connotations of fantasy and, as you mentioned, brings it in to a category that involves many things that bear no relationship to theism.
As far as debate goes, it is a form approaching ad hom/straw manning. Bringing a target within the confines of a category with retrograde credibility makes the task of taking it down that much easier.
I'm pretty sure you would take reserve to reductionist views of life as being labelled "supernatural", even though it can be presented in such a manner to tick all the aforementioned boxes you have given.
Also, as an interesting point of history, when Newton first brought forth his ideas of gravity, he faced charges of masquerading as a fraudster from the scientific community since he was talking of intangible forces. He even described gravity as supernatural. His idea of thinking is that there is no way to empirically explain or investigate what causes a universal constant to manifest its universal qualities.
This is the point where one has to make the decision whether or not to "blur the line", as you stated earlier.
Does science claim that viewing the observable universe as a closed system of entirely natural phenomena exhausts reality?
Or is that the claim of atheists?
No doubt you will choose this moment to inject the stock standard response of atheists having no claims to make.
Answering in that way will not however explain on what basis one could level such a claim about "natural" phenomena and reality. To say the least, science is not demanding such philosophical conclusions. So who else does that leave in the room?
