Throughout the 17th and 18th centuries, storms of contention and division continued to plague the churches of Europe. During these two centuries there was an eclipse of official, church-to-church attempts at unity. Instead, ecumenical witness was made by individuals who courageously spoke and acted against all odds to propose Christian unity.
In England, John Dury, a Scots Presbyterian and (later) an Anglican minister, “a peacemaker without partiality,” traveled more extensively than any other ecumenist before the 19th century. He negotiated for church unity in his own country and in Sweden, Holland, France, Switzerland, and Germany. Richard Baxter, a Presbyterian Puritan, developed proposals for union, including his Worcestershire Association, a local ecumenical venture uniting Presbyterians, Congregationalists, and Anglicans.
Efforts were undertaken in Germany and central Europe as well. The German Lutheran George Calixtus called for a united church between Lutherans and Reformed based on the “simplified dogmas,” such as the Apostles’ Creed and the agreements of the church in the first five centuries. Nikolaus Ludwig, Graf (count) von Zinzendorf, applied his Moravian piety to the practical ways that unity might come to Christians of all persuasions. The philosopher Gottfried Wilhelm Leibniz worked tirelessly for union between Protestants and Roman Catholics, writing an apologia interpreting Roman Catholic doctrines for Protestants. John Amos Comenius, a Czech Brethren educator and advocate of union, produced a plan of union for Protestants based upon the adoption of a scriptural basis for all doctrine and polity and the integration of all human culture.
Eastern Orthodox Christians also participated in the search for union. Metropolitan Philaret of Moscow and the Russian Orthodox theologian Aleksey S. Khomyakov expressed enthusiasm for ecumenism. Cyrillus Lukaris, Orthodox patriarch of Alexandria and later of Constantinople, took initiatives to reconcile a divided Christendom. People throughout Europe held tenaciously to the dream of ecumenism, although no attempt at union was successful. 19th-century efforts
A worldwide movement of evangelical fervour and renewal, noted for its emphasis on personal conversion and missionary expansion, stirred new impulses for Christian unity in the 19th century. The rise of missionary societies and volunteer movements in Germany, Great Britain, the Netherlands, and the United States expressed a zeal that fed the need for church unity. Enduring the harmful results of Christian divisions in different countries, Protestant missionaries in India, Japan, China, Africa, Latin America, and the United States began to cooperate.
In 1804 the British and Foreign Bible Society, an interdenominational Protestant organization, came into existence to translate the Scriptures into the world’s vernaculars and distribute the translations throughout the world. This was followed, 40 years later, by the founding of two important Christian organizations in England: the Young Men’s Christian Association (YMCA; 1844) and the Young Women’s Christian Association (YWCA; 1855). Their international bodies, the World Alliance of YMCAs and the World YWCA, were established in 1855 and 1894, respectively. The Evangelical Alliance, possibly the most significant agent of Christian unity in the 19th century, held a unique place among the volunteer associations of the age. Founded in London in 1846 (the American section was established in 1867), the alliance sought to draw individual Christians into fellowship and cooperation in prayer for unity, Christian education, the struggle for human rights, and mission.
Also pivotal in the 19th century were advocates for the visible unity of the church. In the United States, where the most articulate 19th-century unity movements were heard, the witness to the unity and union was led by three traditions. The Lutherans Samuel Simon Schmucker and Philip Schaff pleaded for “catholic union on apostolic principles.” Among Episcopalians, the visionaries for unity included Thomas Hubbard Vail, William Augustus Muhlenberg, and William Reed Huntington, who proposed the historic “Quadrilateral” of the Scriptures, the creeds, the sacraments of baptism and the Lord’s Supper, and episcopacy as the keystone of unity. Thomas Campbell and his son, Alexander, and Barton Warren Stone, members of the church of the Disciples of Christ, taught that “the Church of Christ on earth is essentially, intentionally and constitutionally one.” Ecumenism was enflamed in the hearts of 19th-century Christians and in the next century shaped the churches as never before. Ecumenism since the start of the 20th century
The 20th century experienced a flowering of ecumenism. Four different strands—the international Christian movement, cooperation in world mission, Life and Work, and Faith and Order—developed in the early decades and, though distinctive in their emphases, later converged to form one ecumenical movement.
The modern ecumenical era began with a worldwide movement of Christian students, who formed national movements in Great Britain, the United States, Germany, Scandinavia, and Asia. In 1895 the World Student Christian Federation, the vision of American Methodist John R. Mott, was established “to lead students to accept the Christian faith” and to pioneer in Christian unity. The World Missionary Conference at Edinburgh (1910) inaugurated another aspect of ecumenism by dramatizing the necessity of unity and international cooperation in fulfilling the world mission of the church. In 1921 the International Missionary Council (IMC) emerged, bringing together missionary agencies of the West and of the new Christian councils in Asia, Africa, and Latin America for joint consultation, planning, and theological reflection. The Life and Work movement was pledged to practical Christianity and common action by focusing the Christian conscience on international relations and social, industrial, and economic problems. Nathan Söderblom, Lutheran archbishop of Uppsala, inspired world conferences on Life and Work at Stockholm (1925) and Oxford (1937). The Faith and Order movement, which originated in the United States, confronted the doctrinal divisions and sought to overcome them. Charles H. Brent, an Episcopal missionary bishop in the Philippines, was chiefly responsible for this movement, although Peter Ainslie, of the Disciples of Christ, shared the same vision and gave significant leadership. World conferences on Faith and Order at Lausanne (Switzerland; 1925), Edinburgh (1937), Lund (Sweden; 1952), and Montreal (1963) guided the process of theological consensus building among Protestants, Orthodox, and Roman Catholics, which led to approval by the Faith and Order Commission of the World Council of Churches of the historic convergence text Baptism, Eucharist, and Ministry (1982).
The World Council of Churches (WCC) is a privileged instrument of the ecumenical movement. Constituted at Amsterdam in 1948, the conciliar body includes more than 300 churches—Protestant, Anglican, Eastern Orthodox, and Oriental Orthodox—which “confess the Lord Jesus Christ as God and Saviour according to the Scriptures and therefore seek to fulfill together their common calling to the glory of the one God, Father, Son, and Holy Spirit.” Its general secretaries have been among the architects of modern ecumenism: Willem Adolph Visser ’t Hooft (Netherlands), Eugene Carson Blake (United States), Philip Potter (Dominica), Emilio Castro (Uruguay), Konrad Raiser (Germany), and Samuel Kobia (Kenya). The witness and programs of the WCC include faith and order, mission and evangelism, refugee and relief work, interfaith dialogue, justice and peace, theological education, and solidarity with women and the poor. What distinguishes the WCC constituency is the forceful involvement of Eastern and Oriental Orthodox churches and churches from the developing world. Through their active presence the WCC, and the wider ecumenical movement, has become a genuinely international community.
