Hi there. I wrote an answer sometime ago that might provide you with the insight you're looking for. Your question is a bit broad, so the linked comment is talking mainly about my tribe. It shouldn't be taken as sweeping generalization.

Additionally, the book Removable Type: Histories of the Book in Indian Country, 1663-1880 by Phillip H. Round is a great source of information for the spread of Christianity and the Bible throughout Indian Country. Vine Deloria, Jr., a Native American scholar and author, has a book entitled God is Red and details interfaith between Native American religions and Christianity as well.
