Nerwen,
I concur. I certainly could have said this in fewer words. But unfortunately, many other people require more evidence. I am quite happy to expound upon long lines of text.
Meteorites being sacred is not new, but that's not the point. It is the metaphysical principles that come from such rare phenomena (cosmic catastrophe) that encompasses Morality (that which exists by function/relation).
Respectively, if you would have noticed this occult theme of Tolkien, Turin's sword shall have seemed to drive a chasm between human subjective law by action and divine accommodated law.
Furthermore, who's to say Eru actually speaks anthromorphically? I contend he doesn't. In all other ancient Creation myths, there are narratives where a Creation god "speaks" as if the man was already present as a created (structural/origin theory) being. This is anachronistic if you fall into the mindset of anthropomorphism. Eru "speaks" as he is defined, yet unchanged by the successive cycle of Ages. They are not mere words (Tolkien's parallelism is undeniable). Eru enables his foremost Beings to sing "themes." This is not an anthropomorphic choir. This is a visual look into the Ages of Good (limitation) and the Ages of Evil (Chaos). Ages of Good are met with the growth of boundaries (Elves), while balanced by the destruction of Chaos (Melkor). Both are necessary for the balance of nature and the eventual subsumation of Eru, the One. As Eru says, anything Morgoth does he providentially aides Eru in keeping the balance.
