There is a whole school of Lorca criticism that sees his work as a secret code to be deciphered. Eutimio Martín thinks that Lorca's project was to develop a "fifth gospel" of a humanist messianic-quixotic type. Martín thinks he is rescuing Lorca from "folklore."
My refutation is very simple: if that's what Lorca was about, how come he didn't say so? Why encrypt such an important message? At the risk of being somewhat literal minded, I think that Lorca is about what he seems to be about. There is some Christological stuff in his juvenilia, true, but he left it behind him for good reasons. The mature Lorca didn't really want to be Jesus any more.
