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.
Psycho-analyzing the Bible or history 2000 years ago may be good for speculation but it’s too subjective to build doctrine on.
