During this course, we have learned how some features of the world’s societies have changed and how other features have remained the same by focusing on some historical themes: 1) power and authority structures; 2) revolutionary moments; 3) economic systems; 4) cultural developments; and 5) scientific/technological innovations. For your final assignment, select two of these themes and demonstrate: a) how some elements of each theme have changed over the period of time covered in this course; b) how some elements of each theme have stayed the same over the period of time covered in this course; and c) how someone holding a Christian worldview would interpret the change and continuity of your selected themes differently from someone holding a secular worldview.
