(John Ernest), a very learned writer in the beginning of the 18th century, a native of Königsberg in Prussia. He was educated in the Lutheran religion; but the reading of the fathers led him into doubts. He presented to the electoral consistory at Sambia in Prussia a memorial containing his doubts. The elector gave orders to three eminent divines to answer them. Their answers shook him a little in his resolution of embracing the Roman Catholic religion; and one of them, Spener, advised him to go to England. He went; and king William gave him a pension, which was continued by queen Anne. He was ordained a priest of the church of England, and honoured with the degree of doctor of divinity by the university of Oxford; upon which occasion Dr George Smalridge pronounced two Latin orations, which were afterwards printed. He wrote, 1. Spicilegium S. S. Patrum, ut et Hereticon faculps Christi nationem, 8vo. 2. An edition of the Septuagint, from the Alexandrian manuscript in St James's library. 3. Notes on Justin, &c.; and other works, which are esteemed by the learned.
