There are lots more Lutherans than Calvinists. And Calvinism has all of those scary doctrines like double predestination and the limited atonement, whereas Lutheranism is, well, happier, with its emphasis on the certainty of grace, Christian freedom, and its affirmation of the secular realm as God’s hidden kingdom. And yet it’s Calvinism that has been so influential in English and American Christianity and the culture as a whole. So marvels D. G. Hart, himself a confessional Calvinist and a perceptive scholar of American Christianity. Read his ruminations after the jump, and then offer your own theories about why this is.
UPDATE: Anthony Sacramone, former Calvinist who is now a Lutheran, has a very helpful response.
