In 1872 the Missouri Synod joined with other orthodox synods, forming the Evangelical-Lutheran Synodical Conference. At present this is composed of the synods of Missouri, of Wisconsin, of Minnesota, of Michigan, and of the English Evangelical-Lutheran Synod of Missouri and other States. The synods of Wisconsin, Minnesota, and Michigan have united to form a general synod and possess several institutions for the education of pastors and teachers. Their theological seminary is at Milwaukee. The Norwegian Synod, which confesses the same faith, also has several educational institutions. The English Synod at present has colleges at Winfield, Kans., and Conover, N. C. All these synods are indefatigable in the work of mission and in the preservation of the pure doctrine. The mustard seed has become a tree, a tree whose branches cover not only the states of the union and a great part of British America, but whose twigs extend even to South America, Europe, Australia, and Asia; a tree continually growing new shoots beneath which birds of passage from every province of Germany and from every country of the world have found their home, and raise their hymns in the most diverse melodies to the honor and praise, glory and worship of the triune God. Everywhere, nearly all over the globe, is sung: "Dear Christians, One and All, Rejoice," and from countless lips Luther's hymn of battle and triumph is heard, "A Mighty Fortress is Our God!"
