The fandom lotr wiki lists four times eru ilúvatar intervened in the history of arda I believe that tolkien several times calls melkor/morgoth the most powerful being created by eru, the most powerful of the ainur, the most powerful of the valar, etc. Creating elves and men removing aman from the spherical earth resurrecting gandalf making gollum trip in a let.
If eru is the creator of all that is, does this make him the most powerful force in the tolkien universe Gandalf's body lay on the peak for nineteen days, until he was resurrected by eru and sent. Has he created beings, such as sauron, which have more power than him?
Is it at all related to any words in primitive quendian, for example?. But eru granted men death as a gift (only to have it be thought of as a curse because of morgoth) and when they wished to die they could leave arda Did eru give men the gift of death as a way of showing he favors them more than elves? For eru, the history unfolds as it must since the music has been played and history will follow it
In the published books, eru is a bit of a jerk here Melkor's dissonances made eru's themes stand out better in the music The consequence is that melkor's evil will make the story of the world better because it makes eru's work stand out better. Eru tripped gollum, according to the lotr wiki, thus destroying the one ring
If my silmarillion memory serves, both are names of the ultimate creator When should one used over the other? After gandalf died from the injuries he sustained whilst fighting the balrog, he was resurrected by eru
