Popularising a convoluted point of theology for the unlearned by an illustrative story gets the point across.Then, several generations later, when the story falls into the hands of the author of Matthew who may well believe that the Jonah story is true he has his own fictional Christ figure quote Jonah to give authority to a different theological point: death can be conquered. We see passages taken captive by your pen and pressed into service to win you a victory, which in volumes from which they are taken have no controversial bearing at all ...the line so often adopted by strong men in controversy – of justifying the means by the result.""Do you see the advantage of deceit?
