Pope Leo quoted Gandalf in Encyclical (churchpop.com)

"It is not our part to master all the tides of the world, but to do what is in us for the succour of those years wherein we are set, uprooting the evil in the fields that we know, so that those who live after may have clean earth to till."

A shot at the Tolkien-obsessed SV dipshits who think they understand theology better than anyone else?
