I would take issue with "purely religious". Nothing in the the persecutions of the 16th and 17th centuries were purely religious. Much, if not all had a lot to do with social class, and political power. More on that later.
Thank you for inspiring me to read about the Great Awakening. It is very interesting and I look forward to reading more about and by Jonathan Edwards. Do you share my assessment that the Great Awakening was a departure from Calvinist doctrine?
Jonathan Edwards and George Whitefield were two of the most vigorously Calvinistic preachers in history.
