A warning to folks who are not Christian. This is a post about Christianity. And given that Tolkien was a devout Anglican, I feel it is appropriate at times to discuss how his personal beliefs are expressed in his writing. This is not an attempt at evangelism. If you are not a Christian, I am totally cool with that. Be what feels right to you and works for those around you. I'm a Christian and like it. It gives me hope. I like Tolkien, and so sometimes I see things in his writings that are ideas that we might perhaps share.
My mind was wandering in church today, and I had a thought. Given that today is Pentecost, I was thinking about the trinity.
The three elven rings might, it seems be seen as an expression of the trinitarian nature of God.
Vilya was Elrond's ring. Given that he ruled a strong elven kingdom and was known as a great loremaster and sought out by people for his advice and wisdom, this ring seems like it would have the characteristics of God the Father. In that in rules, creates and gives wisdom.
Nenya is Galadriel's ring. Given that her realm is closest in spirit and nature to the days of elves in their past glory, this ring seems to sustain. Thus it has characteristics that we might see in Christ the son.
Narya, Gandalf's ring is fire! It inspires and gives inspiration in dark times. This sounds like the inspiration of the Holy Spirit.
Well that's the extent of my musings.
