ESCHATOLOGIST — [Noun] A specialist in eschatology, the systematic doctrine of final matters: the ultimate destiny of the soul, the end of history, and the cosmos. From eschatology, from the Greek ἔσχατος (éskhatos, "last, furthest") + λόγος (lógos, "study, discourse"), + the agent-noun suffix -ist. Unlike a general theologian, who surveys the entire terrain of divinity, or an apocalypticist, who is transfixed by the cataclysmic machinery of revelation, the eschatologist is the cartographer of the terminus itself. His work is the quiet calibration of scales for the Final Judgment, the patient parsing of metaphors for a New Jerusalem, and the comparative study of heavenly geographies across civilizations—a scholar who makes his home at the edge of all thought, contemplating the period at the end of history's sentence.
