“as well as using human psychology”
Must have missed that particular hermeneutic.
Given that much of the gospel narrative is human dialogue, eg Pharisees, Sadducees, even Herod + Pilate; there are other academic disciplines that can be brought to bear as being potentially illuminative. As Dylan said - don’t criticise what you can’t understand. Drivers of human behaviour havn’t changed much over the years - power, greed etc.
