In sharp contrast to this Augustinian tradition is that of the Old and the New Testament as understood by the Fathers of the Roman Orthodox Ecumenical Councils. The “spirit” of man in the Old and New Testaments is that which is sick and which in the patristic tradition became also known as “the noetic energy” or “faculty.” By this adjustment in terminology this tradition of cure became more intelligible to the Hellenic mind. Now a further adjustment may be made by calling this sick human “spirit” or “noetic faculty” a “neurobiological faculty or energy” grounded in the heart, but which has been short circuited by its attachment to the nervous system centered in the brain thus creating fantasies about things which either do not exist or else do exist but not as one imagines. This very cure of fantasies is the core of the Orthodox tradition. These fantasies arise from a short circuit between the nervous system centered in the brain and the blood system centered in the heart. The cure of this short-circuit is noetic prayer (noera proseuche) which functions in tandem with rational or intellectual prayer of the brain which frees one from fantasies which the devil uses to enslave his victims.
