Gandalf, Aragorn and Frodo each can be regarded as a Christ figure. I can't remember where I read it, but it has been suggested that Gandalf represented Christ the prophet, Aragorn Christ the King (who returns to establish his Just Kingdom) and Frodo Christ the Sacrifice. Each undergoes either a symbolic or in Gandalf's case real death and rebirth (Frodo actually undergoes two of them I think...).
There are hints through the books that the Ring did not come to Gollum, Bilbo or Frodo by chance. In other words, in some sense providence plays a role in the destruction of evil.
I could dig more out but you said you just wanted one or two
Well, I did ask
I don't remember ever reading Tolkien admitting deliberate Christian themes, but can't say categorically. Themes of prophecy, sacrifice, rebirth, providence, and higher forces are as old as ... well, let's just say older than Christianity. (I did have more written here, but such discussion really belongs in the Politics and Religion forum.)
