Radical Christians are always making use of the culture, or parts of the culture, which they ostensibly reject. - H. Richard Niebuhr

In Protestant history the sect has ever been the child of an outcast minority, taking its rise in the religious revolts of the poor, of those who were without effective representation in church or state. ... By its very nature the sectarian type of organization is valid only for one generation. The children born to the voluntary members of the first generation begin to make the sect a church long before they have arrived at the years of discretion.

The ideal which was implicit in Jesus’ teaching became explicit in Paul. Not only did this apostle refuse to recognize the religious differences between the parties of Peter, Apollos, Paul, and Christ, but — what is more important — he showed his converts that in Christ there can be neither Jew nor Greek, male nor female, bond nor free, and that with God there is no respect of persons. Recognizing the diversity of gifts he resisted the ever-present tendency to find in diversity the excuse of division.

The church, as an organization interested in self-preservation and in the gain of power, has sometimes found the counsel of the Cross quite as inexpedient as have national and economic groups. In dealing with such major social evils as war, slavery, and social inequality, it has discovered convenient ambiguities in the letter of the Gospels which enabled it to violate their spirit and to ally itself with the prestige and power those evils had gained in their corporate organization. In adapting itself to the conditions of a civilization which its founder had bidden it to permeate with the spirit of divine love, it found that it was easier to give to Caesar the things belonging to Caesar if the examination of what might belong to God were not too closely pressed.
