In 1850 Robertson began his
Church History, his major work; volume i. appeared in 1852, and volume iv., bringing the narrative to the
Protestant Reformation, in 1873. This initial edition consisted of four volumes. A revised edition (in 8 vols.), entitled
History of the Christian Church from the Apostolic Age to the Reformation, was issued in 1874–5. While still a curate Robertson wrote a book entitled
How shall we conform to the Liturgy? (1843, 3rd edit. 1869). It argued the impossibility of a literal compliance with all the rubrics, and the consequent need of tolerance and elasticity. Other works were: •
Peter Heylyn's
History of the Reformation (1849), editor. • Writings on the
Gorham case (1850). •
Olshausen on the Romans (1850), translator. •
Sketches of Church History, for the Christian Knowledge Society (pt. i. 1855, pt. ii. 1878). •
Becket: a Biography (1859). •
Plain Lectures on the Growth of the Papal Power (1876). He also edited
John Bargrave's
Alexander VII and the College of Cardinals (Camden Soc. 1866), and for the Master of the Rolls
Materials for the History of Archbishop Thomas Becket (vol. i. 1875, vol. vi. 1882); the last volume was completed after Robertson's death by his coadjutor, Dr. J. Brigstocke Sheppard. Besides his other work, he was a learned contributor to the
Quarterly Review. ==Family==
