Samuel Marinus Zwemer (April 12, 1867 – April 2, 1952), nicknamed The Apostle to Islam, was an American missionary, traveler, and scholar. He was born at Vriesland, Michigan. In 1887 he received an A.B. from Hope College in Holland, Michigan, and in 1890, he received an M.A. from New Brunswick Theological Seminary in New Brunswick, New Jersey His other degrees include a D.D. from Hope College in 1904, a L.L.D. from Muskingum College in 1918, and a D.D. from Rutgers College in 1919.

After being ordained to the Reformed Church ministry by the Pella, Iowa Classis in 1890, he was a missionary at Busrah, Bahrein, and at other locations in Arabia from 1891 to 1905. He was a member of the Arabian Mission (1890–1913). He is the founder of American Mission Hospital in Bahrain.

Zwemer served in Egypt from 1913 to 1929. He also traveled widely in Asia Minor, and he was elected a fellow of the Royal Geographical Society of London.

On 1 October 1930, he was appointed at the Princeton Theological Seminary, as the Professor of the History of Religion and Christian Missions, where he taught until 1937. He had married Amy Elizabeth Wilkes on May 18, 1896. He was famously turned down by the American Missionary Society, which resulted in him going overseas alone. He founded and edited the publication The Moslem World for 35 years. He was influential in mobilizing many Christians, especially doctors, nurses, preachers and teachers, to go into missionary work in Islamic countries.

Zwemer retired from active work on the faculty of Princeton College Seminary at the age of seventy, but continued to write and publish books and articles as well as doing a great deal of public speaking. Zwemer died in New York City at the age of eighty-four.

According to Ruth A. Tucker, Ph.D., Samuel Zwemer's converts were "probably less than a dozen during his nearly forty years of service" but his "greatest contribution to missions was that of stirring Christians to the need for evangelism among Muslims".

Career 
In his biography of Raymond Lull, Zwemer divided Lull's ministry threefold and we may use the same broad categories to examine Zwemer's own ministry: Evangelism, Writing and Recruitment.

Evangelism 

In 1889, Zwemer co-founded with James Cantine at the Seminary, the American Arabian Mission. Zwemer saw his first milestone in his ministry as leaving for Arabia in 1890 to work directly with the Muslim community. At this time, his main mode of evangelism was distribution of literature and personal conversation. He combined models of confrontational and a more irenic approach of presenting the love of Christ, 'characteristic of the student volunteers'. Stories of his spontaneous interaction with people suggest that he was a capable and creative personal evangelist.

Writing 
In the tradition of Lull, Zwemer 'left behind a mighty highway of print almost a book a year in English for over half a century.' As part of this great literary undertaking, he settled in Cairo in 1912 to work with the Nile Mission Press to make it 'a production point for Christian Literature for Muslims.' As an outcome of the Edinburgh World Missionary Conference in 1910, he established the quarterly The Moslem World in 1911 because 'If the Churches of Christendom are to reach the Moslem world with the Gospel, they must know of it and know it.' He edited it until 1947, paying for much of it out of his own pocket. He founded the American Christian Literature Society for Moslems (A.C.L.S.M) which raised over a quarter of a million dollars for the production of evangelical literature. Its Constitution expressed Zwemer's belief that the printed page 'has a unique value as a means of carrying the Gospel to Mohammedans... [it] finds an entrance into many doors closed to the living witness and can proclaim the Gospel persistently, fearlessly and effectively.' Zwemer saw printed page as 'the "leaves for the healing of the nations" in his program of mission strategy.'

Recruitment 
Zwemer's third milestone was accepting a professorship at Princeton in 1929 and marked an era of equipping and recruiting for the missionary movement, though this had been a significant aspect of his career from the beginning. In an extended period of furlough he was a traveling representative for the Student Volunteer Movement, and his speaking ability in motivating for missions was legendary. His itinerary was herculean: in America in 1914 he gave 151 addresses in 113 days across the country. W.H.T. Gairdner called him 'a steam engine in breeches'. His talent for fundraising was equally impressive, one year raising $32,886 for the Reformed Board of Foreign Missions, when the salary of a missionary on the field at this time was $900 a year.  J. Christy Wilson Jr. summarizes: 'Speer and Zwemer probably influenced more young men and women to go into missionary service than any two individuals in all of Christian history.'

Legacy 
As a result of his direct pioneering work, four mission stations had been set up, and though only small in number, 'the converts showed unusual courage in professing their faith.' The resulting church in Bahrain of the National Evangelical Church of Bahrain continues to this day.  It is impossible to know how many people were affected by the large volume of tracts and scripture that he helped distribute. His books continue to make a significant difference today and his quarterly journal remains in publication as a significant scholarly journal. Through the work of the Student Volunteer Movement, with which Zwemer was strongly connected, 14,000 young people went out to the mission field.

Beliefs

Theology 
Zwemer's theology, following the Calvinism of his parents, was that he saw the supremacy of God in all things. The Bible was programmatic in his faith and his thinking of his ministry, and emanated in his vocabulary. He studied Islamic Doctrine of God, initially drawing stark contrasts with the God of the Bible, then nuancing his view over time. He praised the all encompassing idea of God in Islam, seeing it as the 'Calvinism of the Orient,' and even placed the Bismillah on his study wall in Cairo and on the cover of his journal "The Moslem World". He saw Islam's grasp of Monotheism as its great strength and yet also its great deficiency. For him, without an understanding of the Trinity, God was unknowable and impersonal. Hence, he cherished the doctrines of the Incarnation and the Atonement, writing major works on the topics: The Glory of the Manger and, his favorite, The Glory of the Cross. Though a stumbling block for Muslims, he saw them as crucial in evangelism. Zwemer's God was glorious and all-encompassing: 'never be satisfied with compromise or concessions', demanding instead 'unconditional surrender'.

Missiology  
Zwemer's all-encompassing vision of God was the driving force of his missiology: 'The chief end of missions is not the salvation of men but the glory of God.' He sees this grand vision as coming directly from Calvin:  'God has created the entire world that it should be the theater of his glory by the spread of his Gospel.' It was this unshakable belief in the infinite power and supremacy of God that drove Zwemer to the 'cradle of Islam' as a demonstration of the 'Glory of the Impossible'. His confidence of the victory of the Gospel in the Middle East was equally unshakable. Still, this missiology of victory is fundamentally shaped by the cross: 'Christ is a conqueror whose victories have always been won through loss and humiliation and suffering.' This was hardly academic for Zwemer, since he had lost his brother and two daughters in the field. Lyle Vander Werff describes Zwemer's missiological approach as 'Christocentric-anthropological', that is, the Gospel message is the greatest need of the Muslim as opposed to Western Civilization or 'philanthropic programs of education'. Zwemer summarizes his theology of mission: 'With God's sovereignty as basis, God's glory as goal, and God's will as motive, the missionary enterprise today can face the most difficult of all missionary tasks—the evangelization of the Moslem world.'

Ecclesiology  
For Zwemer, the Church was precious because it was indeed 'the Church of God which He purchased with His own blood.' His view on denominations was ecumenical and generous and far from the parochial tendency occasionally demonstrated in the Reformed tradition. The Arabian Board he set up was expressly 'undenominational.' He is able to praise Popes Gregory VII and Innocent III. He longed for the day Oriental Orthodox Churches would join in with Muslim evangelism. His opening editorial for The Moslem World stated that it aimed 'to represent no faction or fraction of the Church, but to be broad in the best sense of the word.' His slogan was: 'In essentials it seeks unity, in non-essentials liberty, and in all things charity.' Yet, he was clear and precise about what the essentials were. Such desire for ecumenism was fed by his all-pervasive passion for mission to Islam: 'the issues at stake are too vital and the urgency too great for anything but united front.'
