As a matter of fact, "feet of clay" in psychoanalysis refers to the moment when someone realizes that their parents are not mortal. And the closest connection to Cao Dai I can find is that Caodaists practice ancestor veneration, hence the "ghost of your father" theme. This plus the blowout (sudden rupture) makes me think the facade he's trying to build up of forgetting and forgiving his father (stepfather in John's case) has suddenly collapsed on itself.
