In 1862, at the age of 14, Davidson became a pupil at Harrow School. The school was Anglican in its religious teachings and practices, and he took part in confirmation classes. Scarlet fever prevented him from being confirmed along with the other boys at Harrow, and he was confirmed in June 1865 at St George's, Hanover Square by the Bishop of London, Archibald Campbell Tait, a longstanding friend of Henry Davidson. The greatest influences on Davidson at Harrow were Henry Montagu Butler, the headmaster, and Brooke Foss Westcott, his second housemaster. Davidson was inspired by Butler's sermons and by Westcott's wide-ranging instruction on topics from architecture and poetry to philosophy and history. Davidson and Westcott became lifelong friends, and each came to turn to the other for advice.
