The ransom sacrifice is the elaboration of a perfectly dreadful story. It is based on the most primitive and yet dramatic means of restoring the equilibrium in a tribal society. It is the belief that for the sake of the unity of the tribe and for the appeasement of the gods; someone has to die.
The idea was formalised in early Egyptian Horus/Osiris myth and perpetuated by successive tribes and powers in the region. Over time each group and regional cult would add in their own local notions but the essence of the story remained.
Had it not been for Jewish dissidents looking for a god-man saviour of their own and labelling him Jesus, we would know this same myth as the death and redemption of the crucified saviour Dionysus.
Although Christianity and the JW org would instantly die if it was understood... yet it is a fundamental matter of education to know when we are dealing with myth or with fact.
Hint: if the text contains accounts of people coming back from the dead or talking animals or invisible spirits; it is a story or myth.
