Having taken orders in the English church, he had rapid preferment. The rectory of Lee in Kent and the second prebendal stall in Rochester Cathedral were conferred upon him in 1773. In the following year he was appointed to the rectory of St. George, Hanover Square, and he vacated his stall at Rochester; but he was one of the prebendaries of Exeter from 1772 to 1794, and he retained the fourth prebend at Rochester from 1783 to 1797. Early in 1794 he was nominated to the bishopric of Bristol, his consecration taking place on 11 May; and after three years was translated to the see of Exeter (March 1797), holding the archdeaconry of Exeterin commendam from that year until his death, and retaining as long as he lived his London rectory. He died in Lower Grosvenor Street, London, 9 June 1803, and was buried in the cemetery of Grosvenor Chapel.
