requirements for Christian union to human teachings and institutions, nor do they limit them to merely a part of the divine doctrines of the Bible. They err neither _in excessu_ nor _in defectu_. Accordingly, Lutherans, though not unmindful of the admonition to bear patiently with the weak, the weak also in doctrine and knowledge, dare not countenance any denial on principle of any of the Christian doctrines, nor sanction the unionistic attitude, which maintains that denial of minor Christian truths does not and must not, in any way, affect Christian union and fellowship. In the "Treatise on the Power of the Pope" the Book of Concord says: "It is a hard thing to want to separate from so many countries and people and maintain a separate doctrine. But here stands God's command that every one shall be separate from, and not be agreed with, those who teach falsely," etc. (Sec.42.) 6. Misguided Efforts at Christian Union.--Perhaps never before has Christendom been divided in as many sects as at present. Denominationalism, as advocated by Philip Schaff and many Unionists, defends this condition. It views the various sects as lawful specific developments of generic Christianity, or as different varieties of the same spiritual life of the Church, as regiments of the same army, marching separately, but attacking the same common foe. Judged in the light of the Bible, however, the numerous sects, organized on various aberrations from the plain Word of God, are, as such, not normal developments, but corruptions, abnormal formations, and diseased conditions of the Christian Church. Others, realizing the senseless waste of moneys and men, and feeling the shame of the scandalous controversies, the bitter conflicts, and the dishonorable competition of the disrupted Christian sects, develop a feverish activity in engineering and promoting external ecclesiastical unions, regardless of internal doctrinal dissensions. For centuries the Pope has been stretching out his arms to the Greek and Protestant Churches, even making concessions to the Ruthenians and other Uniates as to the language of the liturgy, the marriage of priests, the cup to be given to the laity, etc. In order to present a united political front to the Pope and the Emperor, Zwingli, in 1529, offered Luther the hand of fellowship in spite of doctrinal differences. In political interests, Frederick William III of Prussia, in 1817, forced a union without unity on the Lutherans and Reformed of his kingdom. In America this Prussian Union was advocated by the German Evangelical Synod of North America. The Church of England, in 1862, 1874, and 1914, endeavored to establish a union with the Old Catholics and the Russian Church even at the sacrifice of the _Filioque_. (The Lutherans, when, in 1559 and again in 1673 to 1681, negotiations were opened to bring about an understanding with the Greek Church, insisted on unity in the doctrines of Justification and of Free Will, to which Jeremiah II took exception.)
