Shaw Clifton was born on 21 September 1945 in Belfast, Northern Ireland. Clifton was commissioned as an officer of The Salvation Army on 5 July 1973. His first appointment was to Burnt Oak Corps, in the British Territory in July 1973. He went briefly to continue his theological studies at International Headquarters in October 1973, before being appointed in January 1975 with his wife, Helen, to Zimbabwe, initially to the Mazowe Secondary School and then to Bulawayo as corps officers. He returned to the United Kingdom in 1979 to take charge of Enfield Corps, North London. In June 1982 he became the legal and parliamentary secretary at International Headquarters. This was followed by an appointment in 1989 to Bromley Corps in South London. In May 1992 he became Divisional Commander in the Durham and Tees Division of the United Kingdom Territory with the Republic of Ireland. He served in that post until 1995. He was promoted to the rank of Lieutenant-Colonel and appointed Divisional Commander in the Massachusetts Division of the USA Eastern Territory for two years. He was appointed as Territorial Commander of the Pakistan Territory of The Salvation Army in 1997 with the rank of Colonel, later promoted to the rank of Commissioner while still in Pakistan where the work of the Army prospered during his service there. In 2002, he became Territorial Commander of the New Zealand, Fiji and Tonga Territory. In 2004, he was returned to the United Kingdom territory this time as Territorial Commander until, at the Army's 16th High Council held at Sunbury Court, Sunbury-on-Thames, London, he became General-elect of The Salvation Army on 28 January 2006, taking office in succession to General John Larsson on 2 April 2006. He served a five-year term, entering retirement in 2011. He married Commissioner Helen Clifton, who was born in 1948 in Edmonton, London, on 15 July 1967. They have three children, Matt, John and Jenny. Two are officers in The Salvation Army. Commissioner Helen Clifton was world president of women's ministries and has been a Salvation Army officer since 1973. In 1984 they jointly edited a book 'Growing Together' about marriage and family life. On 13 September 2007, Clifton became a Freeman of the City of London. In November 2007 he was diagnosed with early and operable cancer and, on medical advice, all overseas travel was cancelled or postponed until the end of June 2008. Meanwhile, he continued to carry out all the usual functions of the office of the General of The Salvation Army. Medical treatment and surgery led to a return to full health. Overseas travel with full public engagements resumed in August 2008. Clifton and his wife entered into retirement on 2 April 2011. Helen Clifton was diagnosed with cancer in August 2010 and died on 14 June 2011. In October 2013 Clifton married Birgitte Brekke, an officer of The Salvation Army, and of Danish nationality holding the rank of commissioner and currently overseeing the Army's operations throughout Europe. She was formerly married to Bo Brekke, of Norwegian nationality, who was killed in Pakistan in 2007 in the course of his role as territorial commander of The Salvation Army there.
During his years in office, Clifton maintained a close interest in the connection between Christianity and social-ethical issues. He helped to shape current Salvationist positional statements on issues such as abortion, war, race and ethnicity, gender, marriage and family life, euthanasia, human sexuality and pornography. Clifton advocated a role for churches in social action, not just in social service, important though the latter is. Such a role should be a non-party role and it is not for the churches to tell believers or members how to cast their vote. When he served as world leader of The Salvation Army Clifton actively worked for heightened awareness of, and greater opposition to, human trafficking. His convictions on the Army's calling to work for social justice gave rise to the establishing of the international social justice commission based in New York near to the United Nations. He brought to the role the same interest in ecumenical relations shown in earlier appointments around the world. He encouraged still greater freedom of contact between the Army and other branches of the Body of Christ, including the Roman Catholic Church and enhanced communication with the Vatican. A strong believer in the equality of men and women in Christian leadership, Clifton consistently sought to promote talented women Army leaders into more senior roles. He emphasized the use of modern communication techniques in Christian ministry and encouraged a proactive book publishing programme by The Salvation Army's International Headquarters in London and around the world. He is known for writing and speaking on the practical possibility of living a pure and holy life in the secular world, by divine indwelling and grace. He draws upon the writings of the Reformers, John Wesley, William Booth, Catherine Booth, Samuel Logan Brengle, and Edward Read. In retirement he continues to write, preach and teach.
