I enjoyed reading Paul Helm's recent blog article at Helm's Deep on Edwards on the Trinity (link). Prof. Helm defends Edwards from various charges of Heterodoxy in the course of the article. Naturally, as one of the standards for Reformed orthodoxy, Helm and Edwards' critic both refer to Turretin (with Helm placing Turretin in context). The title of the Blog, though reminiscent of Tolkien, is quite appropriate, since Helm's work plumbs great depths.
