Part One of the book makes a few important arguments. Rather than going into detail into all of them here, I will draw your attention to two of them.
The first argument is that the United States and Europe have carried out two very different paths of the relationship between religion and state. What are those paths? Why were they so different?
A second argument is that the different paths have different implications for the degree of religiosity in those two regions. What is the logic of this claim? What reasons do the authors give in making the argument?
Be sure to understand these arguments. You may want to go back and read
through the book again to reinforce the important ideas. You might also want to look at blog posts for prior years on the God is Back book.
