Monotheism:  Constantly changing, morphing, adapting to maintain its chokehold in a world that becomes increasingly more explainable through science.

An awful lot like a virus.

You don't want to allow the cultural memes (environmental movement) to leave your religious ideology appearing as if it is archaic or no longer relevant.  In the same way, scientific revelations must be addressed to appear as if they coexist with the xtian ideology or if this cannot be done, then attack these revelations as unsubstantiated or untrue (hello creationism, ID).

Must always adapt to maintain its relevance and increase the # of adherents or run the risk of whithering away.
