Perception and dedication backed up by documentation mark this appeal to men of good will to understand and act their roles as Christian witnesses. Attacking the religious establishment as too often complacent and unwilling to lead in the areas of social justice and special emphasis on the Negro, Father Berrigan supplies a pattern for rectifying the scandal he sees being promoted by even the well intentioned. Particularly telling is his relating of race, the Nuclear Arms race and the Christian Conscience. Father Berrigan calls for a change from a religion centered about the negative to a positive demand for exercising Christian duty. He calls for a questioning and a reform of the Christian ""credo"" even in its absolutes so as to determine further development and clarify expression. The Church's resources are seen as available essentially for engagement with life, which to Father Berrigan means other men. This fervent and intelligently presented plea for exploring love on all levels and all its facets in concrete detailed form should be welcomed by all concerned with social issues of our time.
