The Salvation Army's main converts were at first alcoholics, morphine addicts, prostitutes and other "undesirables" unwelcome in polite Christian society, which helped prompt the Booths to start their own church. The Booths did not include the use of sacraments (mainly baptism and Holy Communion) in the Army's form of worship, believing that many Christians had come to rely on the outward signs of spiritual grace rather than on grace itself. Other beliefs are that its members should completely refrain from drinking alcohol (Holy Communion is not practised), smoking, taking illegal drugs and gambling. Its soldiers wear a uniform tailored to the country in which they work; the uniform can be white, grey, navy, fawn and are even styled like a sari in some areas. Any member of the public is welcome to attend their meetings.
