List of Religions from the Dune Universe
Fremen Religion
The Fremen religion was a religion widely practiced on Arrakis by the Fremen. The faith got formed on the ways of the Wandering Zensunni, the ancestors of the Fremen. Although the wandering Zensunni practiced a pacifistic religion, the Fremen followed survival and strength.
The book of Kreos was the religious book the Zensunni philosophers used in their teachings, and it got preserved even after the Fremen fundamentally changed the nature of their ancestors. Many elements from the Fremen religion got formed by their environmental factors. The sandworms got seen as Shai-Hulud and Shaitan, good and evil. The Fremen had the Sayyadina, a woman that acted as a spiritual guide. The Sayyadina became a reverend mother by taking the water of life.
After Paul rose to become the emperor, the Fremen started a Jihad that wiped out more than 40 religions throughout the universe. With the Fedaykin as priests, the Fremen spread their religion to every corner of the universe. By the end of the Fremen jihad, the Fremen religion had become the predominant faith in the universe.
The Bene Gesserit Way
The Bene Gesserit got enlightened in many religions of the Imperium; this was because of the Missionaria Protectiva they used to input seeds of religious legends into primitive cultures. The Bene Gesserit believed in the Orange Catholic Bible.
The Bene Gesserit were rooted in education than religion. The matriarchal order defined a specific method that enabled its sisters to become reverend mothers who could access the memories of their female ancestors; this ability got called Other Memory. Another aspect Bene Gesserit focused on was politics. The sisterhood was vested in governing humanity through a breeding program that created the ultimate superhuman, the Kwisatz Haderach.
Sardaukar Religion
Though the Sardaukar were secretive with their faith, evidence showed that they followed the way of warrior-mysticism. Their religious beliefs came to be because of the wandering Zensunni Misr. The Sardaukar’s religion got heavily influenced by Judaism and Islam propagated by the religious institutions Tawrah Collegiate and the Talmudic Zabur. With their religious beliefs, the Sardaukar considered themselves to be superior beings.

What are some quotes from the Orange Catholic Bible?
Some quotes from the Orange Catholic Bible are:
“The Universe is God’s. It is one thing, a wholeness against which all separations may be identified. Transient life, even that self-aware and reasoning life which we call sentient, holds only fragile trusteeship on any portion of the wholeness.”
“Much that was called religion has carried an unconscious attitude of hostility toward life. True religion must teach that life is filled with joys pleasing to the eye of God, that knowledge without action is empty. All men must see that the teaching of religion by rules and rote is largely a hoax. The proper teaching is recognized with ease. You can know it without fail because it awakens within you that sensation which tells you this is something you’ve always known.“
