The Soldier's Covenant, called the Articles of War until 1989, is signed before a person is enrolled as a soldier, and its commitments are specific: abstinence from alcohol, tobacco and non-prescribed addictive drugs, from gambling, and from pornography; the maintenance of a Christian home; the wearing of uniform as directed; and support of the corps by giving and by service. Total abstinence has been a boundary marker since the 1870s and comes directly from the Army's constituency — the Booths worked among people whose lives had been dismantled by drink, and the pledge was an instrument as much as a rule. It has produced periodic institutional awkwardness, most publicly when the Army has inherited properties or businesses with liquor licences. Adherents, who worship with the corps without signing the covenant, are a separate and growing category.
