GRAEBE, JOHANN ERNST. – Patrologist, Protestant, b. Königsberg in 1666, d. Oxford in 1711. He taught from 1685 at the University of Königsberg. The reading of Bellarmine’s writings turned him toward Catholicism.
In his *Dubia* addressed to the Lutheran Church Council, he accused Luther of heresy. Only the intervention of the Pietist Spener prevented his conversion. In 1697 he emigrated to England, became Anglican, and took up residence in Oxford. Famous for his patristic writings, which were intended to contribute to the reunion of the Churches: *Spicilegium patrum primaeque aetatis* (2 vols., Oxford 1698–99; 3rd ed. 1712; 4th ed. 1714; 5th ed. 1714); edition of Justin’s *First Apology* (ibid. 1700), of Irenaeus (ibid. 1702). His masterpiece was the edition of the Septuagint, based on the Codex Alexandrinus (vols. I and IV, ibid. 1707–1709; vols. II–III, posthumous, ibid. 1719–20).
