The movement of withdrawal and renunciation is a necessary element in every Christian life. ... It is an inevitable answer; but it is also inadequate… - H. Richard Niebuhr

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.

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. ...

The Christian .. cannot dismiss the philosophy and science of his society as though they were external to him; they are in him. ... He cannot rid himself of political beliefs and economic customs by rejecting the more or less external institutions; these customs and beliefs have taken up residence in his mind.
