In the late 1800s and early 1900s, German scholar Ernst Troeltsch sought to impose a meaningful pattern on this confusion by organizing the complex relationships of the Christian community to the world into three types of religious social organization: church, sect, and mystical movement. He described the church as a conservative institution that affirms the world and mediates salvation through clergy and sacraments. It is also characterized by inclusivity and continuity, signified by its adherence to baptism and historical creeds, doctrines, liturgies, and forms of organization. The objective-institutional character of the church increases as it relinquishes its commitment to eschatological perfection in order to create the corpus Christianum, the Christian commonwealth or society. This development stimulates opposition from those who understand the Gospel in terms of personal commitment and detachment from the world. The opposition develops into sects, which are comparatively small groups that strive for unmediated salvation and that are related indifferently or antagonistically to the world. The exclusivity and historical discontinuity of the sect is signified by its adherence to believers’ baptism and efforts to imitate what it believes is the New Testament community. Mystical movements are the expression of a radical religious individualism that strives to interiorize and live out the personal example of Jesus. They are not interested in creating a community but strive toward universal tolerance, a fellowship of spiritual religion beyond creeds and dogmas. The Methodist church exemplifies the dynamic of these types. The Methodist movement began as a sectarian protest against the worldliness of the Church of England, and its success stimulated it to become a church, which in turn spawned various sectarian protests, including charismatic communities.

Niebuhr further developed Troeltsch’s efforts by distinguishing five repetitive types of the Christian community’s relations to the world. Niebuhr’s types are: Christ against culture, Christ of culture, Christ above culture, Christ and culture in paradox, and Christ the transformer of culture. The first two are expressions of opposition to and endorsement of the world, while the last three share a concern to mediate in distinctive ways the opposition between the first two.

Opposition to the world is exemplified by Tertullian’s question, “What has Athens to do with Jerusalem?” This sharp opposition to the world was expressed in the biblical disjunction between the children of God and the children of the world and between “the light” and “the darkness” (1 John 2:15, 4:4–5; Revelation), and it has continued to find personal exponents, such as Leo Tolstoy, and communal expressions, such as the Hutterites.

Endorsement of the world emerged in the 4th century with the imperial legal recognition of Christianity by the Roman emperor Constantine I. Although frequently associated with the medieval efforts to construct a Christian commonwealth, this type is present wherever national, social, political, and economic programs are “baptized” as Christian. Thus, its historical expressions may be as diverse as the Jeffersonian United States and Hitlerian Germany.

The other three types that Niebuhr proposed are variations on the theme of mediation between rejection and uncritical endorsement of the world. The “Christ above culture” type recognizes continuity between the world and faith. This was probably best expressed by St. Thomas Aquinas’s conviction that grace or the supernatural does not destroy nature but completes it. The “Christ and culture in paradox” type views the Christian community’s relationship to the world in terms of a permanent and dynamic tension in which the kingdom of God is not of this world and yet is to be proclaimed in it. A well-known expression of this position is Martin Luther’s law–gospel dialectic, distinguishing how the Christian community is to live in the world as both sinful and righteous at the same time. The conviction that the world may be transformed and regenerated by Christianity (“Christ the transformer of culture”) has been attributed to expressions that have theocratic tendencies, such as those of St. Augustine and John Calvin.

Efforts by scholars such as Troeltsch and Niebuhr to provide typical patterns of Christian relations to the world enable appreciation of the multiformity of these relationships without being overwhelmed by historical data. These models relieve the illusion that the Christian community has ever been monolithic, homogeneous, or static. This “many-sidedness” may be seen in the Christian community’s relationships to the state, society, education, the arts, social welfare, and family and personal life.
