This is Francis Turretin's magnum opus, a massive work of Reformed scholasticism. Written originally in Latin with sentences frequently lasting nearly a half a page, Turretin's Institutes are at once familiar, profound, erudite, thorough and precise, detailed, comprehensive, historically significant, and truly Reformed, etc. Turretin organized his Institutes into 20 topics (loci) that range from "Prolegomena" (that is, very necessary introductory considerations) to "The Last Things." Each topic (locus) is organized by specific questions. The work is Elenctic (polemic or argumentitive), for a large chunk of this work is written against the Roman Catholics, Arminians, Socinians, Anabaptists, Molinists and others.
