Katapetasma, “The Demonized Gerasene and the Paganized Greek: Eschatological Allegory in Mark 5:1-20” (8.17.20), scribesofthekingdom686237748.wordpress.com.
This deliverance of the gentile wrought by the destruction of Legion also brings judgement upon those who refuse to abandon the defunct pagan order—and herein lies the source of the people’s anxiety and of their request for Jesus to relinquish the territory (Mark 5:14). Those gentile townsfolk who respond to the Gerasene “seated and in his right mind” with trepidation do so because the pagan system upon which they rely has suffered a symbolic defeat: that is, Rome’s days are now numbered. Jesus’ reign over the Decapolis is at hand.
