Lyric discussion by camd419 

yes: oedipus is the Greek tragedy about the boy who killed his father and then slept with his mother. It is supposed to represent ultimate inevitability (because Oedipus had meant to do neither). Freud's psychoanalysis (in which he was looking for recurring images in myth) attempted to show that this idea - the father-son competetion for the sexual resources of the clan - is part of an underlying strata of human existence.

The song, of course, also represents Christian linearism (beginning/middle/end as opposed to neverending cycles).
