Hi Tyler, can I firm up your first point- that Frodo is like baby Jesus? In the novel, Frodo is age 51, so how does that work out?

And you're finding Frodo's ascent of Mount Doom very similar to Jesus' descent to Hades. But Jesus seems to have preached to spirits in the scene of 1 Peter 3:19, not really melting a ring. Are you sure this is a good match?
