A while back, a friend of mine told me that Christopher Nolan's Interstellar was an allegory for the Holy Trinity. Here was his evidence:
SPOILERS... obviously. Too many to mark up.
Cooper represents different members of the Trinity at different times in the movie.
The Father. He separates himself from his children and the only communication that can happen is essentially one way. His children send videos into space (prayers) knowing that a response is unlikely. At one point, Tom mentions that he doesn't even know if anyone is listening to his message.
The Son. Cooper was humanity's only hope of overcoming certain death. 12 people (12 apostles) are sent ahead to spread humanity (the church). 1 of them betrays him (Judas). Cooper must decide to willingly die so that he can obtain the key for humanity's survival (atonement). He descends below all things and emerges alive (resurrection).
The Holy Ghost. Murph's "ghost" communicates with her, telling her what is needed to save herself and humanity. This communication is subtle, similar to the whisperings of the Holy Spirit. The information is also passed through the books in Murph's library, a symbol of teaching through the Bible.
There are a handful of other tidbits throughout the movie that add to this theory. The beings that show Cooper the way inside the tesseract, were ascended humans from the future, like angels. The theme of man's discovery of his place in the universe. The fall and reconciliation of Murph with her father. Secular textbooks denying man's destiny to ascend to the stars. The fields burning in the end. Not to mention that the whole score is done on a church organ.
All of this seems unlikely to be coincidental symbolism to me, and some Christian websites and bloggers seem to agree. Has any of this been confirmed by Nolan or anyone else involved with the production of the movie?
