Career
He had resolved to join the Church of Rome when a commission of Lutheran divines pointed out flaws in his written argument and called his attention to the English Church as apparently possessing that apostolic succession and manifesting that fidelity to ancient institutions which he desired. He came to England, settled in Oxford, and made heavy use of the Bodleian Library. He was ordained in 1700, and became chaplain of Christ Church.
His inclination was towards the party of the nonjurors. The learned labors to which the remainder of his life was devoted were rewarded with an Oxford degree (DD) and a royal pension. He died on the 3rd of November 1711, and in 1726 a monument was erected to him by Edward Harley, Earl of Oxford, in Westminster Abbey.
He was buried in Old St. Pancras Church, London on 9 November 1711. His name is listed on Baroness Burdett Coutts Memorial as one of the important graves lost. Some account of Grabe's life is given in Robert Nelson's of George Bull, and by George Hickes in a discourse prefixed to the pamphlet against William Whiston's Collection of Testimonies against the True Deity of the Son and of the Holy Ghost.
Dr George Smalridge (who also granted him his degree) wrote a biography of Grabe.
