People should get to know Spizona's ideas. Note: I support all peaceful religions. Spinoza's ideas are close enough to this notion: that God is also Nature; for Spizona, we're not bytes in God's computer, we're literally part of God's (infinite) mind -- Nature itself. This is a really beautiful interpretation of Christianity, and absolutely compatible with science and all modern knowledge. God is hence all knowing, and immortal; God loves all existences (which are all themselves pieces of God). I think if religions are to survive healthily (and contribute to everyone's lives), they should become compatible with science and truth.
The greatest implication is that we are responsible for good ourselves, and if heaven exists, something like us (or our descendants, or other beings entirely) it's up to us to build it (which I couldn't agree more). We should start now!
So call it Nature, why do you need a separate theological construction to realize all of nature is part of the universe which all came from the same start in the big bang and we should all respect each other? Is there really a need for anything else?
The idea is metaphysical -- you're literally a fragment of a greater mind. Like, a cell should respect its host organism -- it's basically redefining what or who you are.
I don't know if there is an absolute need for something else, although clearly you do need some ethical framework to make decisions. Assuming you're a self-interested cell can have definitely different implications than assuming you're literally a tiny part of a whole (even if you are in favor of self-interested cooperation: this redefinition has many further implications). You could also assume you're are a cell, but decide to axiomatically value the whole as well. One way you could justify this axiom is through parsimony -- saying it's simpler than only valuing the self. Another justification (without appealing to Spinoza's definition) is that self-interested cells will fail in certain situations, s.t. whole-valuing cells can go much further -- that is, self-interested cells can turn into cancer or just don't survive as well as a multi- or omni- cellular organism. People already value their children and other people, this is a mostly logical conclusion.
This isn't just academic: we're going through crises right now that would be very different if people were less exclusively self-interested, and humanity's survival may depend on it in some way.
I like to put it this way: Love is optimal.
I think ultimately most ethical systems converge (to fundamentally valuing one another), so in a way some differences are aesthetic, how you prefer to think about it, etc. I think it's nice that we have more than one way of seeing those things coexisting peacefully (although like I said, I think it's very important they are consistent with the truth, at least for the most part).
Sounding a bit dismissive, you just said what I said in more words. My question is why you need god in the discussion, I think it's perfectly fine to have that awareness of being part of the whole without any god in the picture. It can sound like just semantics but for many people once you use the word god, there's a lot of other meanings.
Yes, it's a little difficult to picture (or maybe you might fundamentally disagree) -- but it's like there a literal being, God, that constitutes all of this (I also associate this with the idea of an 'omnimind' -- that all consciousness are literally a part of a same mind). Also, the coherence with Christian (and maybe Abrahamic in general) traditions makes it an interesting interpretation of ethics in the sense of there existing a God in a literal sense (and other premises of those traditions being consistent in this framework). I recommend reading or taking a course into Spinoza if you're interested, because there's more than I can describe without writing a little book (although I think some of the conceptions I have are fairly original -- Spinoza afterall lived in mid 17th century).
To get a feel for an expanded mind, think about your cellphone (or PC or google, etc.). Some of your memories are stored in your cellphone. So in a very real way the digital world is an actual extension of your mind; think how some of our organs (like hair, or maybe cartilage etc.) are not living tissue yet we consider them part of 'us'. The definition of 'I' is in a way functional, and maybe more completely related to agency and information coherence. In a literal way also, Nature doesn't distinguish individuals. What is 'you' here is, as far as we can tell, a large amount of flowing interactions, which are not singular. What is 'you' is influenced by an entire past extended lightcone; what is 'you' does not live in a single moment in time, but is indeed distributed in time and in space -- 'I' is an abstraction over a cosmic soup -- a very useful, interesting, and important one, but nonetheless it isn't physically fundamental. What we are fundamentally changes in time as well -- you are fundamentally a distributed network of events, not a singular entity. In this way the fundamental distinction of individual seems to fade, and validate a greater distinction -- the maximum distinction is the one encompassing all that exists (i.e. Spinoza's God). In a way, you might call it just another way of seeing things -- just like the 'I' or the self -- but it can in the same way be interesting, useful, etc.. And again it fits the traditions in a way (this is also an insight of Buddhism but the interpretation is different).
I don't think Christians would agree that God is Nature. Christians believe that God created nature, but that he is outside of it. This is in contrast with some older religions that do worship nature. It is not a coincidence that Christian God is "the Father" while nature is "Mother Nature".
The greatest implication is that we are responsible for good ourselves, and if heaven exists, something like us (or our descendants, or other beings entirely) it's up to us to build it (which I couldn't agree more). We should start now!
