But what does that make Jesus then? ... Son of evil demigod?


No, that I don't think so. Jesus was son of God as much as we all are. But what made him special was that he remembered his divine origins.

But the God worshipped in OT is not the God of love. The Source, the real God is above all rules and there is no such thing as sin or hell. Those are just man made fear based systems to make us obey and stay in leash.

I know since the real God of love has spoken to me. And He said:
God is love and love is God.
Trust your heart, that is my temple - not any building made of stone - and fear not,
There is no end.
There is only love for those ready to accept their divine origins.
Namaste and Amen.
