The smartest Jewish thinkers would call today's religion heresy.
At its best, Judaism never feared questions. It embraced complexity, speculation, the unknown. But in many religious communities today, innovation is suspect and questioning is a threat.
People ask if I believe in God.
But the question itself feels off. What does God even mean?
If God is to explain the complexity of the world, He cannot Himself be complex. A complex God raises more questions than He solves. Richard Dawkins, The God Delusion
The God that Richard Dawkins rejects a bearded old man in the sky, handing out commandments, smiting sinners isnt even the God of classical Jewish theology. The God of RaMCHaL¹ isnt a complex being in need of explaining. Hes the opposite. The very essence of simplicity itself. No multiplicity. No division.
You must also know that the Blessed One is simple, without any equivocation or multiplicity at all, and all the perfection we say He has is in a form of complete simplicity. RaMCHaL, Derech Hashem
The Ein Sof (endless in Hebrew) is unchanging, the way He always was and always will be, without any change at all. RaMCHaL, Sod HaYichud
This goes on and is an excellent theological read:
