The story of Bramwell Booth reporting the men sleeping under the arches of London Bridge, and his father telling him to go and do something for them, is the Army's account of how it became a social agency, and it is told to make a doctrinal point rather than a sentimental one: the Army holds that the two halves of its work are one work. The scale is now enormous — homelessness services, addiction rehabilitation, disaster relief, anti-trafficking work, family tracing, the thrift stores and the Christmas kettles — and it is the reason most people in most countries have an opinion about The Salvation Army without knowing it is a church. The Army has been publicly criticised, particularly in the United States and the United Kingdom, over its positions on same-sex relationships and over the employment and service policies attached to them; it has revised public statements more than once and the argument continues.
