The first third of this book is very interesting, covering the history of oppression among Native American peoples and some of how Christians view time and history versus how Native Americans do.

Thus concludes all the positive things I would like to say about this book. The highlights of the rest of my feelings:
-This book was written in the 70s and I believe that a lot of the thoughts in this book are hard to apply past that time period.
-The chapter(s) dealing with Velikovsky and his very unproven theories (and how Deloria treats them as fact, and how you're stupid if you don't give them value) were the tipping point for me. Ridiculous theory, and it didn't validate any of his arguments anyway.
-Speaking of arguments, I couldn't tell you what Deloria's thesis is in this writing. It is scattered, and some of the things that might be his thesis, he contradicts multiple times.
-Deloria treats Christianity as a monolith. And I wasn't alive in the 70s, so I can't speak for what Christians as a whole were like/doing/etc. But! There are a few things that (at least now) are not very true that are said about Christians and their beliefs and I had a hard time getting past that. Some things, I absolutely agreed with him on. Some things, I don't think I'd ever been raised to believe as a Christian myself. So though that was interesting to see someone's sorta outside view on, it felt very heavy-handed.
 
This was maybe the most disappointing read I've had. I expected something that had a thorough critique of Christianity and the way most Christians in America seem to have neglected what Native Americans have historically upheld-the value of land and community and being in harmony with the environment and the spiritual, and ways that that has impacted the Native people, and proposing a better way that aligns with the people born on the American land. 
 
There can still be value found in the book. However, it left a bad taste for me and I wouldn't recommend it whole-heartedly, or even half-heartedly.
