Pantheism -
Panentheism -
Now, I always thought of myself as Pantheist, but I recently descovered there is Panetheism which is a completely new vies on things (for me). Can somebody explain me more about the second one. What is the key difference?
I feel like you haven't got a very direct answer?
Pantheism: Everything in the universe is divine / made of divinity / suffused with divinity. God = Universe
Panentheism: As above, PLUS, god is also outside / above / beyond the universe
So in both of them, god = the universe, but in panentheism, god is also more
Schopenhauer said pantheism was a kind of atheism because it's possible to say "god is the universe" in a way that, say, Carl Sagan or Einstein might. To redefine "god" so that it means the material universe, and it's not really what a religious person would think of as god at all. But that's not the only way to do pantheism.
I would say that if you believe in Heaven, you need panentheism, because Heaven is outside the universe.
In a lot of mainstream religions, the world is not divine, and god lives outside the world.
So panentheism is kind of like paganism + mainstream religion put together (god is both part of the universe and outside the universe at the same time)
(I disagree with the "pantheism = gnostic" and "panentheism = agnostic" thing. Some Gnostic groups were pantheist and some weren't. If I were to generalise, Gnostics often believe that the earth was a mistake, created by an evil or at least idiotic creator who did a bad job, so I would generally say that is not pantheistic - since they are viewing the world as bad, not holy. Gnostics also usually believe there is a god outside of the universe, so panentheist is a better fit than pantheist.
"Agnostic" just means you don't know if god is real or not so you can be agnostic about any version of god.
It's possible Ziran is using gnostic and agnostic to mean something different)
