When William Booth became known as the General, Catherine is known as the "Mother of The Salvation Army". William Booth's early motivation for The Salvation Army was to convert poor Londoners such as prostitutes, gamblers and alcoholics to Christianity, while Catherine spoke to the wealthier people, gaining financial support for their work. She also acted as a religious minister, which was unusual at the time; the Foundation Deed of the Christian Mission states that women had the same rights to preach as men. William Booth described the organisation's approach: "The three 'S's' best expressed the way in which the Army administered to the 'down and outs': first, soup; second, soap; and finally, salvation."
