The only son of John Stearne, by his wife Dorothy, daughter of Charles Ryves, examiner in the chancery of Ireland, he was born in Dublin. He was educated at the cathedral school under Mr. Ryder, and entered Trinity College, Dublin, on 2 April 1674, his tutor being Philip Barbour. He graduated B.A. 11 February 1677, M.A. 12 July 1681, and D.D. in July 1705. Having been ordained deacon in October 1682 by Anthony Dopping, bishop of Meath, Sterne served for a time as his domestic chaplain. About 1688 he was made vicar of Trim, County Meath; in October 1692 he was instituted to the rectory of Clonmacduffe, and in June 1703 to that of Killary, both in the diocese of Meath. On 11 September 1702 he was installed chancellor in St Patrick's Cathedral. On the death of his mother's kinsman Jerome Ryves, Sterne was elected dean of St. Patrick's, by the chapter, with the support of Jonathan Swift, then prebendary of Dunlavin. In July 1707 Sterne was instrumental in the election of Swift to represent the chapter in Convocation. Soon afterwards he joined a small social club to which belonged Swift, Stella, and their common friends, the Walls and the Stoytes, who met on Saturdays for cards and other diversions. Swift's letters during this period are full of allusions to Sterne. When a vacancy occurred in the diocese of Dromore, Swift named Sterne to Bolingbroke and Ormonde. Ormonde raised difficulties, and Sterne had enemies among the Protestant clergy in Ireland; but Ormonde then gave way, so that Swift could have the deanery. Sterne was consecrated bishop of Dromore on 10 May 1713,> and in March 1717, on the move of St. George Ashe to Derry, he was translated to Clogher. There, as at Dublin and Dromore, he was famed for hospitality, as Jonathan Smedley noted. In 1721 Sterne was appointed vice-chancellor of Trinity College, to which in 1726 he presented a sum of £1,000 for a university printing-house. In 1732 Sterne endorsed two bills: one for subdividing large preferments, the other for enforcing residence. Nothing came of them, but Swift wrote a devastating letter, dated July 1733. Sterne died at Clogher, unmarried, on 6 June 1745.
Legacy
By his will, dated 13 May 1741, Sterne endowed a large number of local charities, especially Dr Steevens' Hospital and the Blue Coat Hospital, Dublin. He also left money to Swift's hospital for lunatics. He rebuilt the episcopal mansions at Dromore and Clogher, as well as St Patrick's deanery, and he left £1,000 to build a granite spire to St Patrick's Cathedral, in addition to funds towards finishing Clogher Cathedral. He left £50 per annum in exhibition to Trinity College, Dublin, poor scholars of the diocese of Clogher to have the preference. The rarer books in his library he gave to Marsh's Library in Dublin. The remainder were distributed by lot among the poor curates of the diocese. His manuscripts, of which he had a significant collection, he bequeathed to Trinity College, Dublin; among them are the depositions of the sufferers in the Irish Rebellion of 1641.
Works
Sterne's major work was Tractatus de Visitatione Infirmorum. It was translated in 1840 as The Curate's Manual. The Tractatus was reprinted in the Clergyman's Instructor of 1807 and 1813; then in the 1843 edition it was replaced by Bishop Thomas Wilson's Parochialia.
