the injunction from Jesus to hate mother, father, brothers and sisters is really a call for a non-hierarchical society
What has hating your brothers and sisters got to do with rejecting hierarchy? Sibling relationships are the exact opposite of that. Zizek is talking bullshit.
Jesus' words are much more simple than that. He meant what he said - reject your fucking family and follow me.
Jesus was a egocentric cult leader who demanded the same loyalty as every cult leader before and since. The rejection of the family - our most intimate relationships - in favour of the cult is the ultimate test.
If he existed at all, Jesus was both deluded and dangerous.
The NT is very explicit about the reason for Jesus' death. It is ugly and pagan and it does leave god looking like a narcissist. Conflating Job with the meaning of the cross is nonsense.
P.S. What is wrong with Zizek?
