Bombadil and Christ: the First and the Last

Tom Bombadil is the eldest of the creatures in Middle Earth.  As he himself said to the hobbits:

Eldest, that’s what I am.    Mark my words, my friends: Tom was here before the river and the trees; Tom remembers the first raindrop and the first acorn.  He made paths before the Big People, and saw the little People arriving.  He was here before the Kings and the graves and the Barrow-wights.  When the Elves passed westward, Tom was here already, before the seas were bent.  He knew the dark under the stars when it was fearless–before the Dark Lord came from Outside. (Fellowship of the Ring, pp. 148-149)

This description is similar to that of Christ in the Prologue of the Gospel of John:

In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. All things came to be through him, and without him nothing came to be. What came to be through him was life, and this life was the light of the human race; the light shines in the darkness, and the darkness has not overcome it. (Jn 1:1-5)

But Bombadil was only a creature; Christ is God. Bombadil was a spectator; Christ is the maker. Bombadil saw the coming of the Darkness; Christ dispelled the Darkness for He is the Light of the world.

Bombadil and Christ are also both the first and the last:

I think that in the end, if all else is conquered, Bombadil will fall, Last as he was First; and then Night will come. (Glorfindel in the Council of Elrond, Fellowship of the Ring, pp. 298)

I (am) the Alpha and the Omega, the beginning and the end. (Rev 21:6)

But Bombadil shall be conquered at last and die; Christ conquered death and lives forever. Bombadil saw the old order pass away; Christ makes all things new.
