Why not? I just finished reading it again, so here we go. An excellent tale, and how everything is entwined with the fate of these three holy jewels makes it quite intresting, and fluent. If you ask me, the Silmarils, being three, and given the fact they are named Blessed, and have captured in them the light of the two Trees of Valinor unsullied, and light usually being the ultimate subject of 'Good' and practicly the giver of life, I'd say are equivalent (to some extent, not saying that they in fact are an allegorical equality) to the Holy Trinity (being God, Jesus, and The Holy Spirit).
And another intresting thing I have noticed quite evidently throughout The Silmarillion, is the number 7! Here's all the things that are 7 in The Silmarillion (The Book, and not just Silmarillion proper) that I can think of right away:
Sons of Feanor
Gates guarding Gondolin
Swans Tuor saw flying to Vinyamar
Ships Turgon sent to Aman
Rivers that made up the land of Ossiriand
Wounds Fingolfin gave Morgoth afore he hewed his foot from under him
Cries of anguish Morgoth let loose as the above was dealt
Days did Ar-Pharazon march upon M.E. until he set his pavilion on a hill, whence he sent messengers to bring forth Sauron
Fathers of Dwarves were there in the beginning made by Aule the Vala
Some more there were but this is all I can think off, I find it odd that 7 should be such a relevant number, when numbers are indeed brought up. Perhaps it was a number Tolkien chose out of thin air, or because to him was relevant in some way and used it throughout, or a coincedence, though to me it hardly seems so. I think it was inspired by the Bible, as the Silmarillion, if not whole, mirrors the Christian religion in many aspects, as indeed I believe Tolkien admited to. For in the Revelation, even as John saw the vision of the end, there was a lamb with seven horns and seven eyes, which are the Seven Spirits of God, and He whom John saw held Seven Stars in his right hand, and about him Seven Lamps. And the book which God held had seven seals. Not to mention the seven days in which creation took place (well, six, and the last being a day of rest), in Genesis.
Anyway the book was excellent, and I ask anyone else who has read it (and preferably enjoyed, though thou who have rants, I'd like to hear from thee to), please come forth and share with us your questions, concerns, so on so forth!
