I searched for the word “mosaic” in some of my seminary and ministry books to see who was writing about it in the same way Wuthnow and Kinnaman did. By and large, the “mosaic” I found in these searches was referring to not to the concept of being a person or society or world comprised of many pieces put together to form life experience. Rather, it was about Mosaic Law. That is, the Law of Moses from the Older Testament.
I thought that was kind of funny.
