We have out own radical fundamentalists here in this country. They are called Christians. It wasn't bad enough that they murdered hundreds of thousands during the Crusades. It wasn't bad enough that they murdered many more thousands during the Inquisition. They continue to believe that they have the only knowledge of what God wants, and how He wants to be worshipped. HOW ARROGANT!!! And, if you don't worship their way, then you aren't really worthy of respect.
Before [creation...big bang...whatever] the beginning, there was only a benign force that started it all (if you believe EVERY holy book written). I will repeat "BENIGN." Hatred, bigotry, racism, religiousism is not part of God's will. However, I digress. Out of the energy of this Great Spirit came the universe. Therefore, nothing that exists is NOT part of God. By inference, everything that exists is God. Many of the Native American nations have language that referes to the "rock people," "plant people," etc. They have the idea. We are God. The worship of God is actually the worship of ourselves as part of the creation.
In the Ten Commandments, God says that he is a "jealous God." Since we are created in God's image, we are as flawed as God is. The part of God that is Satan embodies all of the evil that God harbors; which He has no trouble inflicting on others.
Over the centuries and millenia, great thinkers Abraham, Solomon, Jesus, Mohammud, etc.) have seen the path to God. They have built that metaphorical bridge to his domain. The problem is that those that try to explain this bridge end up selling the bridge...not the journey to the other side. Our religions have made the bridge attractive, but have no clue how to reach the other side; all their energy is spent on maintaining the bridge. The message is lost.
Mormons, too are stuck on the bridge. They are stuck in a different corner of the bridge from other Christians. The other Christians have no clue that everybody on the bridge must work together to get to the other side.
Personally, I don't see it happening.
