Anglican High Churchman. He was educated at Trinity College, Cambridge, and after ordination as priest in 1819 held the vicarage of Horsham, W. Sussex, from 1821 to 1830, and of Hadleigh, Suffolk, from 1830 to 1833. A year's absence in Germany from May 1824 bore fruit in The State of the Protestant Religion in Germany (1825), warning of the dangers of contemporary rationalism in German theology and attributing this to laxity in relation to creeds and Church formularies and the absence of episcopacy having an authoritative teaching office. It provoked a reply from E. B. Pusey, who in his early years was more sympathetically disposed than later towards German theology. Rose responded to Pusey in A Letter to the Lord Bishop of London (1829). In 1832 he founded the British Magazine to further High Church doctrines. A meeting in July 1833 in his rectory at Hadleigh, attended by W. Palmer (of Worcester College), A. P. Perceval, and R. H. Froude, was an important landmark in the beginnings of the Tractarian Movement. Later Rose became somewhat more critical of the Tractarian ideals. In 1833–4 he held the chair of divinity at Durham University and in 1836 he was appointed Principal of King's College, London.
