Except that it’s not found in Dick…
Apologies for the confusion. “For Mormons, matter came from nowhere. It always was, is, and always will be. Nothing can be annihilated. That, too, is found in Dicks.” The third sentence was a comment on the second sentence. The first sentence was a separate assertion. Hence:
Mormons believe that matter did not “come from” anywhere, because it has always existed.
Dicks says nothing can be annihilated, which belief Mormons also hold (or held).
I personally have never heard of an LDS doctrine that states everything is matter. Do you have a source for that? Spirit is believed to be matter.
I think you mean can I give a name and date, or a link to a paper. Not without more digging than I care to do at the moment. As I do a brief survey, it seems that the focus of the statement I was thinking of, is that spirit is matter, not necessarily that
everything is matter.
Nevertheless, that seems to present a problem. If there are things which are neither spirit-matter nor matter-matter, what are they, and how do they relate to matter? What is their source, how can they exist as immaterial things? From matter comes more matter. Matter does not produce the transcendentals. So what is the source of transcendentals? Are they independent of God, so that God has to make effort to obtain them? Are they superior to God (and gods and mankind), or is God (and gods and mankind) superior to them? In Mormon cosmology, too many things exist at once, too many mutually independent things. A chaos of disharmony that must be forced, if it can, into some arbitrary “Plan” - but who is to say whether another God at the opposite end of the universe has a different Plan?
If God is matter, then God lacks Oneness.
If there is a oneness in the very act of being, or in anything else, then that thing is superior to God. If truth is a unity, undivisible, unrestricted, absolute, then truth is superior to God. So is God superior to truth, or truth superior to God - in Mormon theology/cosmology - and how? and, why is it that way? (I’m thinking out loud, but it would be . . . something . . . to listen to a Mormon trying to explain these things, as (in my opinion) Mormons do not have a very developed, nor a consistent, theology.
If even God himself is the product of evolving matter (“intelligence,” “spirit,” “body,” “resurrected being,” etc.), then when, where, and how are such things as self-awareness, conscience, reasoning, compassion, and so on, introduced? I’m sure no one will argue that a biochemical reaction produces logic, nor that parents (Gods) somehow put lots of compassion into one child (Jesus), but less compassion in another child (Judas), nor that matter can be imprinted with such things.
