A devout and good young man is keen to join the Society of St Pius X. I can understand that. I have always wanted to be simply a priest as Catholic priests are supposed to be. If he is ordained (and he seems to me to be a strong candidate), then he will be able to minister to a largely sympathetic (to the things he stands for, I mean) congregation who will appreciate who he is and what he does. That's the way things are supposed to be between priest and people.
In Lord of the Rings, in a preface Tolkien sharply dismisses the idea that he was writing an allegory. In an allegory one thing directly stands for another; when one has the key, one understands a concrete situation. A myth, however, is something far deeper. It addresses themes which crop up again and again in human history, and tells this in the form of a story whose truth is self-apparent in its root. You can change the story, the characters, but the myth remains essentially the same.
Consider Harry Potter. JK Rowling said that the entire story had sprang into her mind at once. How clever! She conceived of a misunderstood hero who lived away from his natural parents, had extraordinary abilities, had a small group of friends who believed in him, who had a deadly enemy (whom he was the only one able to resist effectively) whom he combatted and by whom he was eventually killed, and who was then raised to life thereby saving everyone else in the story…… Of course it sprang to her mind. It is the greatest story of all, or myth if you will. No wonder a writer without remarkable literary skills managed to write such a bestseller. We all know that story, and it never fails to move us.
I'm conceiving Lord of the Rings in the same way. Right now it seems to me as if the SSPX is Lothlorien. It is necessary that Lothlorien exist, so that we never forget how things should be. Perhaps the FSSP is Rivendell, living to some extent with a foot in two worlds. But we should never forget that the real battle is for the Shire; the parishes and dioceses. If all the soldiers go to live in Lothlorien or even in Rivendell, then the Shire will fall. And if the Shire should fall, then next Rivendell will fall, and eventually Lothlorien too will go. Is Saruman the White now entrenched in Orthanc and holding Gandalf?
You see what I mean about myths?
