I’m a terrible Jonathan Edwards scholar (even though he word a natty pair of bands) and it is a gap in my education that haunts me.
Perhaps the resource Steve McCoy of Reformissionary — who bears a passable resemblance to Jim of Peregrinato — mentions will help: Jonathan Edwards
Edwards is terribly important to Universalist history as Ann Lee Bressler describes in the beginning The Universalist Movement in America, 1770-1880 it was how Federal-era Unitarianism and Universalism responded to Edwardsian theology and not class pressure that lead to their chilly rivalry. (Bressler suggests that the Universalists, having an intrinsic sense of corporate humanity put it closer in the Edwardsian line than the atomistic Unitarians and that knowledge embarrassed Channing.)
George Marsden has written an ambitious and impressive new biography, Jonathan Edwards: a Life, drawing on a lot of newly cataloged original material that had been previously buried in the bowels of the Yale archives. It’s probably the best one-stop source on Edwards out there, and rendered even better by Marsden’s approachable writing style that renders Edwards’ nearly impenetrable thought processes approachable to the only slightly-above-average, only-slightly-more-than-mildly interested beach reader.
