The Christian god was never loving. He has always been an egomaniacal sociopath with an inferiority complex and some mood disorder. Maybe borderline personality disorder. He seems paranoid, controlling, and prone to manipulation and explosive rage when he feels line he has been slighted.
I may be misremembering the DSM negative characteristic map for BPD though. To anyone with BPD out there reading this, I apologize for making a joke at your expense. I know it is a very difficult mental illness to live with, at least when you recognize what is going on. I have known a few people who did not and it wasn’t pretty for those in their life.
