The Society of Friends, for Rufus Jones as for Arthur Roberts, remains a single movement, called by God to a special role in American Christianity and world history. Both men have also been realistically aware of human limitations and diversity. Yet they have seen God's power, shared in meetings for worship as well as in the religious experience of individuals, able to change human society and transcend human ideas and institutions.
