Controversy: fighting over the faith
Controversies have always preceded schisms but have not necessarily resulted in them. After a division, the contesting parties seek to consolidate their respective positions, both among their supporters and against their opponents, so that doctrine takes on an apologetic character even between Christians and acquires—on the assumption that attack is the best form of defense—a polemical edge. As a result, the teaching of each community sometimes suffers through the exaggeration of certain features and the neglect of others.
One controversy that led to schism is the debate between East and West concerning the Spirit’s procession. The Eastern churches have long suspected that the West’s error resides in giving an “Augustinian” priority to an undifferentiated divine essence that in fact renders the distinct persons nonessential to the Godhead. The West, meanwhile, has suspected that the East, by holding to the Father (alone) as “the fount of deity,” may never have overcome the “Arian” subordination of the other two persons of the Godhead.
The other main issue between East and West has concerned the status of the see of Rome. Although the East has recognized that Rome enjoyed a certain “primacy of honour” among the other patriarchal sees of the first millennium (Constantinople, Alexandria, Antioch, Jerusalem), it considers hypertrophic the development by which Rome dogmatized its own claim to universal jurisdiction and an infallible teaching authority.
In the 16th century, Luther’s pugnacity on behalf of his rediscovered gospel expressed itself in combative writings aimed at various targets. The most decisive of those aimed at Rome was the treatise On the Babylonian Captivity of the Church (1520), which attacked the current sacramental system and left Christ himself as the sole sacrament in the scriptural sense (cf. 1 Timothy 3:16) and baptism and the Lord’s Supper as his “sacramental signs.” Luther also attacked the “enthusiasts” among the would-be reformers; at the colloquy of Marburg (1529), rejecting the teachings of Huldrych Zwingli, he proclaimed the existence of the real presence of Christ in the Lord’s Supper with a literal est (“This is my body”). Luther approved the relatively conciliatory Confession of Augsburg (1530), but the Schmalkaldic Articles of 1537 turned fiercely against Rome, which responded at the Council of Trent (1545–63), where it asserted the validity of traditional Catholic teachings in areas of conflict—salvation, sacraments, ecclesiology—and anathematized any who should hold positions that it perceived to exist in Protestantism.
The confessional documents of the Reformation churches typically combined a reaffirmation of the Trinitarian and Christological doctrines of the ancient councils and creeds with a new statement of scriptural soteriology against the current understanding and practice of the Roman Church. They also treated questions of authority, government, and discipline. In sacramental doctrine, the Reformation confessions not only state disagreement with Rome but also reveal certain differences among the various Reformation churches.
Interconfessional apologetics and polemics became built into standard works of theological instruction. A perduring example was Calvin’s Institutes of the Christian Religion (final edition 1559). From the Catholic side, Jacques-Bénigne Bossuet displayed what he saw as the inconsistencies of Protestantism in his History of the Variations of the Protestant Churches (1688).
Nevertheless, the European “wars of religion” of the 16th and 17th centuries resulted, if only by reaction and at a geographically variable pace, in the growth of civil tolerance. An admixture of other cultural factors led to a certain moderation of confessional claims at the intellectual level also; exemplary in this regard would be the German philosopher Gotthold Ephraim Lessing (1729–81). Eventually, the divided churches realized that the task of evangelization, in relation both to domestic secularization and to the global mission, called them to a mutual reconciliation that lay in the nature of the gospel.
An instance of emergent ecumenism, which developed into a broad movement in the 20th century, is found in John Wesley’s Letter to a Roman Catholic (1749) and his sermon Catholic Spirit (1750). Not only on the basis of the universal Creator and Redeemer common to all humanity but also on the grounds of a shared Christian faith (which he set forth as an expansion upon the Nicene Creed), Wesley invited Catholics and Protestants to join in a “union in affection” in which they might “help each other on in whatever we are agreed leads to the Kingdom,” even if differences in “opinions,” “modes of worship,” and church government prevent “an entire external union.”
