In 1850 he was ordained pastor of the Free (Scottish) Church in Chadwell Street, Pentonville, London. The small congregation did not become larger under his ministry. In 1853 he resigned and was appointed to
Milnathort, in the parish of Orwell, Kinross-shire; and in 1857 he removed to Roxburgh Free Church, Edinburgh. In 1862 he was chosen to succeed the Free Church leader,
Dr. Robert Buchanan, in the Free Tron Church, Glasgow. In 1876 he transferred to the Free High Kirk in Edinburgh (part of the New College building). Once settled in Edinburgh he lived at 20 Royal Circus in the
New Town. Smith was a thoughtful preacher, catholic in his sympathies, and of rather advanced opinions for the Free Church of his time, though in the end his influence was felt in broadening its outlook. Two ‘Discourses’ that he published in 1866, advocating more liberal views in regard to Sunday observance than those then prevailing in Scotland, came under the ban of his Presbytery, and he was ‘affectionately admonished’ by the General Assembly in June 1867. In 1876 he was translated to the Free High Church, Edinburgh. During the prosecution of
Professor Robertson Smith his strong sympathy with the professor gave some offence to the orthodox church leaders; but in 1893 he had so won the confidence of the church that he was chosen moderator of the general assembly. ==Legacy==
