The Salvation Army is a Protestant Christian church and an international charitable organisation founded and headquartered in London, England. It is aligned with the Wesleyan-Holiness movement. The organisation reports a worldwide membership of over 1.7 million, consisting of soldiers, officers, and adherents who are collectively known as salvationists. Its founders sought to bring salvation to the poor, destitute, and hungry by meeting both their "physical and spiritual needs". It is present in 133 countries, running charity shops, operating shelters for the homeless, and disaster relief and humanitarian aid to developing countries.
The theology of the Salvation Army derives from Methodism, although it differs in institution and practice; an example is that the Salvation Army does not observe sacraments. As with other denominations in the Holiness Methodist tradition, the Salvation Army lays emphasis on the New Birth (first work of grace) and entire sanctification (second work of grace). A distinctive characteristic of the Salvation Army is its use of titles derived from military ranks, such as "lieutenant" or "major". The Army's doctrine is aligned with the Wesleyan–Arminian tradition, particularly the holiness movement. The Army's purposes are "the advancement of the Christian religion... of education, the relief of poverty, and other charitable objects beneficial to society or the community of mankind as a whole".
