American Indian Pantheism

You've bitten off quite a bit there.

First, customs (at least those having any meaning) were generally confined to a nation or even a band. There is no single generic and authentic Native American religion. (Those that try represent such a religion have created a syncretic religion that does not reflect a wide historical heritage. The Native American Church, for example, has fused elements of Christianity and various Native American ceremonies, most notably the use of peyote, which shows the Southwestern origin of the church's beliefs.)

What "old ways" are these folks turning to? Are they authentic or a modern syncretic creation that has no more to do with their heritage than snake charming? You have to know the specifics.

Are these "old ways" religious or cultural? It becomes very difficult to separate the two sometimes (some American Indians claim that they are entirely cultural and were imbued with "religious" meaning by Europeans, who mistook them for the equivalent of Christian ceremonies and customs.)

I have met many pious Southern Plains Indians who are dedicated Christians — but their religion still maintains a different emphasis than Christians from European traditions; I would be hesitant to say that they have fused religions but rather have accommodated their customs and fit them to the new religion that they wholeheartedly embrace.

Good luck.
