The three-self formula or three-self principle is a missiological strategy to establish indigenous churches. It was first coined in the late-19th century by various missions theorists, and is still used today in certain contexts such as in the Three-Self Patriotic Movement in mainland China.
The three principles of self-governance, self-support (i.e., financial independence from foreigners), and self-propagation (i.e., indigenous missionary work) were first articulated by Henry Venn, General Secretary of the Church Missionary Society from 1841 to 1873, and Rufus Anderson, foreign secretary of the American Board of Commissioners for Foreign Missions. The principles were drafted formally during an 1892 conference in Shanghai of Christian missions reflecting an almost unilateral agreement that the future of the Chinese church depended on the indigenization of the leadership, and the finding of sufficiently Chinese modes of worship. Dixon Edward Hoste, head of the China Inland Mission, was known for putting the same principles into practice in the effort of assisting the Chinese to establish their own indigenous churches during the early 20th Century.
