From July 2018, a little commentary on the matter of the Silmarils, from Pengolodh:

The recovery of a single Silmaril brought on a wealth of misery decay and destruction, and yet these things, outcomes were not wholly evil, nor accounted to Beren’s hubris (though great was it then, less so now).

Second in these doubtful wisely undertaken deeds was his man-emission thereout the Halls of Mandos, whereafter was opened a cut, as it were, for Eru alone to stitch or widen, as suited his inscrutable will.

Third of worse deeds to our Eldari way was his escape herefrom, to return amid halls of light upon Taniquetil; Lawless he appeared, driven to ways beyond the Music, for the sake of preserving intact across orders of living, his love and Varda’s for him.

1. Recovery without reconciliation of oath.

2. Breaking of Mandos’ reign.

3. Return to Taniquetil, with these two cuts.

Thereafter the oath that otherwise would fade with the passing of hroa of Feanor’s sons, now would stand; For these sons would likewise pass thereout those halls, and not for love, but lust of vengeance, and fulfillment of oath against the gainsaying of Ainur, dooms-undying otherwise, now also shown to less their binding, to them free without Arda, and willing condescended hereto.

So Thingol devised his Third way, and all the history of Arda was bent away its straight course to a devious route, yet unreconciled.

The tale of heroes seldom achieve all the unwisdom brought about by the heroes, in their living of them. Only later, perhaps, may the tales’ telling undo what was by heroes wrought; as towers in memorial raised preserve their good in mind, neglecting to upturn all that some hero brought about; to this turning over the takes are commission; and in this the Tale of Eru alone contravenes our understanding; unheroic were his works, yet greater good withheld they for the telling of his deeds, savoring their good for a day like yours, when heroes are out of time for tale’s good telling, that “gospel;”

Here at the End, only the Tale of Eru Living-as-man, Estel-embodied, may redeem mankind, out of stories, and disbelief embodying.  … [S]o this Third Way remains, of Thingol’s: to tell a tale of un-heroes, whose deeds long forgotten, or derided for weakness, may be balm to heal our world in their telling.
