Happer co-founded one of the first
Protestant missions in China through the American Presbyterian Church. The Presbyterian mission was one of the first four American mission agencies in China to carry out missionary work there. Following the Opium War, the
Treaty of Nanking opened five ports for foreign trade. As a result, China became open to missionaries. As one of only 31
Protestant missionaries (3 of them Presbyterian, Happer faced numerous challenges and difficulties. Few resources were available, with China as an intimidating location. Foreigners were not allowed to live in Canton so Happer moved to
Hong Kong and worked and later led at the Morrison Education Society. Happer returned to Macau in 1845 and opened a boy's
boarding school with twenty-seven enrolled students. Although the Opium War treaties had declared that foreigners could access Canton, the Chinese officials refused to let Happer enter the city. He had to move the school to a suburb of Canton. After realizing the responsiveness of the Cantonese people towards education and medicine, Happer opened his first dispensary in 1847. Happer carried out Christian evangelism through the dispensary in various ways, including preaching to his patients and holding chapel services for community residents. Overall, the dispensary treated seven thousand patients annually. This number rose to ten thousand in 1854 after the opening of a secondary dispensary. Management of these dispensaries was handed over to
John Glasgow Kerr that same year. Kerr eventually opened the
Canton Hospital that served a great portion of people from South China. After transferring the responsibility of the dispensaries to Kerr, Happer focused more on providing a Christian-focused western education to Chinese youth.
Second trip to China - Focus on a Education and mission expansion (1859-1869) During his second mission, Happer focused on education and evangelism. He was passionate about converting Chinese individuals to
Christianity and converting society through providing education. In 1850, he opened a set of day schools to educate young Chinese boys in both western and Chinese studies. The schools faced difficulty attracting youth from the upper class who were enrolled in traditional schools that prepared students for the civil service examinations. By December 1853, Happer opened a day school for Chinese girls which offered courses in reading, writing, and economics. By the end of 1853, the first eleven students graduated from the boy's boarding school with two students devoting themselves to the Canton mission. Happer went on medical furlough in 1855 and the
Second Anglo-Chinese War delayed the Happer's return from furlough until 1859. Following the war, however, the treaties produced by the war promoted free and unrestricted access to Canton. This led to an upsurge of missionaries into the Canton with increased conversions to Christianity. In the 1860s, Happer founded the First Presbyterian Church, numerous boarding and day schools, and a training school serving preachers, teachers, and colporteurs of Canton. Happer served as pastor of the First Presbyterian Church in Canton, established in 1862. Through establishing multiple forms of educational services, Happer accomplished his mission of bringing Christian higher education to China, though much of the student body of the training school included those working for the church. In order to reach governmental Chinese leaders through western education, from 1865 and 1867, Happer directed the
Chinese government's Interpreter's College in Canton and taught English and mathematics to students entering government services as foreign specialists. By introducing Christian teachings within his courses, he continued his mission of evangelism and observed the gradual growth of Canton Presbyterians. This is supported by the statistics reported from the Canton Mission that in 1866: 147 individuals were enrolled in mission schools.
Final trip to China - Expanding Education and Religious Outreach (1870-1891) After a 1867 furlough to the US and marriage to his second wife, and revitalized by newfound love and the increasing presence of western influence in China, Happer returned to China in 1870. This missionary period was marked by a change in his missionary career from mission-centric to program-focused. Specifically, this included the local development of “evangelistic, education, and medical programs.”. In his evangelistic efforts, Happer continued being a pastor of the First Church, built a new sanctuary, attracted more upper-class citizens to the church, opened two new churches, and increased overall church membership. ==Contribution to Presbyterian literature==
