Theories of personal development can contribute to the understanding of conscience and conscience formation. (I) Clinical psychologist Carl Rogers has formulated a description of stages in the process of personal growth. While Rogers' stages run parallel to Kohlberg's stages of moral development, they contribute a more sensitive appreciation of some aspects of moral conscience. (II) Kohlberg's idea of conscience appears to be a postconventional phenomenon characterized by moral rationalism. This fact raises certain questions about the value of Kohlberg's work as a paradigm for Christian conscience formation. (III) Both Rogers and Kohlberg contribute to an understanding of conscience. In Christian theology, however, conscience is a multifaceted reality which represents a plurality of moral dimensions. While stage advance describes some characteristics of mature conscience, conscience is a broader reality than either Rogers' or Kohlberg's stages will satisfy to describe.
