Some anabaptists (16th century, around the time of the reformation), Priestley, Newton, also at this time reject the dogmas of the incarnation and the trinity, as they appeared more to be based on Greek philosophical ideas, especially those of Plato.
1. I have been hearing Von Harnack's name mentioned a lot and it has been great to see more of his perspective and influence in this week's trinities podcast. I am particularly grateful as it seems like a lot of the work on the build up to Nicea 325 and Constantinople 381, it is just loose, speculative and unsatisfying. Von Harnack, and apparently Ritchel, may not be right in their hypothesis, but at least we seem to have something a bit more credible. In terms of contemporary influence at the turn of the last century (19th to 20th), he was the most influential scholar, not just theologian. He wrote 900 publications in his life!
