This isn't about Protestants vs. Orthodox. It's about who has the best arguments in support of their positions. Panentheism is simply not defensible philosophically. It's self-contradictory and leads to absurdities. I'm not playing these Ad Hominem type of games.
The Orthodox energy-essence distinction in God also has serious philosophical problems, because it violates the Law of Excluded Middle, which is one of the three fundamental laws of human reasoning. One cannot deny the three laws of human reasoning without first assuming their validity. To deny them, is to affirm them, so it is self-defeating to argue against them
That Wiccan's hold to Panentheism, see Hawkins, "Witchcraft: Exploring the World of Wicca," p. 34). Question: What concord has Christ with Belial? (2.Cor. 6:15).
