A Course in Miracles is a  set of three books that teach that the way to remember God is by undoing guilt through forgiving others. The Course originated in 1965 in response to a request of two psychologists to find another way of relating to others. Many refer to the Course as the "Third Testament,"believing that it represents the same basic theology of the Bible, although in a more spiritually evolved form. The essential characteristic of the Course that lies at the core of our differences is that it is a non-dualistic spirituality . Christianity, as Judaism before it, is a dualistic thought system in which God and the world, spirit and matter co-exist as separate states, both of which are real. Reality is thus seen to be a dimension of opposites - as with good and evil - in marked distinction from the Course's understanding of reality as being only perfect unity in which there are no opposites.Kenneth Wapnick and Rev. W. Norris Clarke, S.J., priest, philosopher, theologian, and Professor Emeritus from Fordham University, engage in this dialogue in order to identify the radical differences, as well as the similarities, between the thought systems of A Course in Miracles and biblical Christianity.
