Aragorn’s distant ancestor, Isildur and his battle with Sauron is a perfect representation of David and Goliath in the Bible. Like David, Isildur faced a massive villain who was defeated by a small act. David flung a small rock; Isildur sliced off a finger. Neither action seems enough to defeat a 9+ foot villain, but in both cases led to the demise of a major participant in the destruction of a life-as-we-know-it type of situation.
As we know, Aragorn is the descendent of Isildur. Who in the Bible do we know that is a descendant of David?
Jesus Christ is a descendant of David just as Aragorn is a descendant of Isildur. In the Bible, Jesus Christ is called by many names, similar to the different names of Aragorn. Jesus Christ wasn’t an ordinary man. He was the son of God. For this reason, he was fit to perform the atonement. Aragorn wasn’t an ordinary man either. He was a dunedain. This made him live longer and even influenced his ability to resist the Ring.
The Ring in the books was meant to embody sin and temptation. Knowing this, simply think of a time in the Bible when temptation had a huge role in the development of Christ. Christ was faced with temptations, and so was Aragorn. Aragorn had the opportunity to take the Ring, but he didn’t, just as Christ didn’t fall to Satan’s temptations.
Throughout the books, elves represent an angelic, godly people. They have magic, similar to God’s power, that made them different. Elves represent everything godly, and to be an elf is to be essentially an angel. The dunedain have elf DNA, this makes them as close to a godly being as any human can be, just as Christ was the most perfect any being touched by humanity can be.
Aragorn bares many similarities to Christ throughout Lord of the Rings, but is definitely not the only representation. The deeper the reader looks into each detail of Tolkien’s masterpiece, the more it can be seen that there was even more to Tolkien’s complex fantasies than what any reader can see. Symbolism is a huge part of Tolkien’s work and gives each read just a little more to learn.
