Actually look what I found:
The relative ease at which the Iroquois Nation was able to provide for the needs of it's people allowed for the development of a systematic belief system that was more developed than most other systems found among Native American civilizations. According to Lewis H. Morgan, their religion is characterized by a monotheistic belief in an all-powerful creator known as the "Great Spirit", or "Ha-wen-ne-yu." "The Iroquois believed in the constant superintending care of the Great Spirit. He ruled and administered the world, and the affairs of the red race." (1954,146). The Iroquois failed to see the need in developing a detailed conception of their creator. This knowledge was thought to be above and beyond their capabilities to understand. His power was administered to the material world through "a class of inferior spiritual existences, by whom he was surrounded." (1954,147). While divine attributes concerning the Great Spirit remained undeveloped, the Iroquois gave detailed descriptions of this lower class of spirits that interacted with the material world. The were known as "Invisible Agents" or "Ho-no-che-no-keh." (Morgan 1954). The power possessed by these spirits was given to them by the Great Spirit and were the manifestations of his unlimited power. Some of these spirits were given names, however, they were often identified with the object or force that they presided over. For example, He-no, one of the more important spirits, was given the thunderbolt and controlled the weather. According to Morgan, he had the form of man and wore the costume of a warrior (1954,147).
While the Iroquois belief system centered around the idea of a benevolent Great Spirit, it did not ignore the existence of evil in the world. Evil is represented by the brother of the Great Spirit, "Ha-ne-go-ate-geh", or "the Evil-minded" (1954,147). This evil spirit exists independently and controls it's own inferior spiritual beings. These agents of evil also exist in the material world and are place there in an attempt to bring about evil. According to Morgan, the Great Spirit does not have any type of positive authority over the Evil-minded, except for the power to overcome him when necessary (1954,148). The red race is left to choose either obedience to the Great Spirit or submission to the Evil-minded. It is important to note that the Iroquois developed the idea of an immortal soul. This soul was judged by the Great Spirit upon the death of the body. The threat of punishment in the afterlife increased morality concerns, which aided in the success of the Iroquois Nation.
The ritual ceremonies practiced by the Iroquois tribes were systematic worship services that occurred in accordance to certain seasonal periods throughout the year. The rituals were handed down through the generation and remained unchanged for centuries. Festival most commonly occurred during important agricultural periods. Worship and thanks were given to the Great Spirit for protection and survival. One of the "Invisible Agents" were usually honored depending on what time of year the ceremony was taking place. The ceremonies were led by "Keepers of the Faith", or "Ho-nun-den-ont" (Morgan 1953,177). They were not an organized priesthood like one would imagine, but rather a loosely organized council of qualified individuals who were assigned the task of maintaining the ritual practices of the Iroquois people.
The belief system of the Iroquois was the closest a Native American civilization had come to the complex theology of Christianity. One major difference between the two religions is evident when looking at how each faith explains mankind's participation in the workings of the universe. While most Christian denominations sought to participate actively in the evolution of their world, the Iroquois say mankind as too insignificant to take part in the grand scheme of the Great Spirit. For example, many Christian denomination, like the Puritans of New England, believed that they were the chosen people of God and were working toward the creation of a true "Kingdom of God" located in America. The Iroquois, on the other hand, believed that the world was as it should be, and there was nothing that could be done by mankind to change this fact. This idea would eventually change somewhat as the Iroquois were influenced more and more by European Christianity. Furthermore, their ideas concerning punishment in the afterlife were also influenced by Christian concepts. According to Morgan, the Christian concept of purgatory seems to have seeped into the Iroquois belief system sometime during the white man's invasion (1954,163). While the Iroquois Nation was the strongest Native American civilization east of the Mississippi river, their integration into the dominant white culture went relatively smooth compared to most other instances of integration among the native tribes of North America. I think this was due to the similarities between their belief systems which made it easier for the two races to find common ground. The religion practiced by Iroquois descendants is remarkably similar to the one practiced by their ancestors. The similarities between the two distinct religions seem to have saved the weaker Native American system from extinction.
I hope this helps... I bet it will. I guess you can call it Hawenneyuism?
