I really don't agree with the comments below. I think that this film is much more about Faith, God and Representation (and therefore about Images, Words and Ideas) than about politics, history or whatever. It's an operatic reflection on Cinema itself, if you want, because the problem of representation that Straub-Huillet examine is an artistic one: in this sense one can compare Art to God (as two forms of creation).
The materiality of words, of bodies, of icons. The struggle to attain what transcends earthly existence and its limits. The film tries to establish its discourse on the basis of a friction between time, space and matter. Dissonances and harmonies pave our way towards the infinite.
