While some of this book is a collection of easily referenced facts, and its basic argument seems to come from a personal place that I can imagine holds water, it then proceeds to make very strange claims about the Bible and about Christian history that scholarship simply does not corroborate.
While he realities that Latino people in America face--the marginalization, the challenges that are common to all immigrants, the intersections of religious and cultural identity as they are reframed by immigration--are certainly worth talking about, the author does so as broadly as possible. For example, spends an entire chapter talking about the importance of understanding diversity among Hispanic people, and then proceeds to conflate Mexican and Hispanic throughout the entire rest of the book, contradicting his own points.
If you were to only read the first section of this book, you might well learn something useful. There are many flaws and I have been deeply troubled by this book, but there is some useful information that is gathered in a helpful way at the beginning.
