The Demonology of the Byzantine Fathers
The Demonology of the Byzantine Fathers
A Study of the Ladder of Saint John Climacus [c. 580-649]
By Deacon Dr. John Chryssavgis
I. Introduction 
The  importance  of  the  demonological  theme in Patristic spirituality  is nowhere  expounded  by  the  Fathers in any  systematic  fashion  but  can  be  gauged  from  their  writings  describing  the  struggle  of  the  human  person,  from  their  anthropology.  In the  Ladder  of  St.  John  Climacus,  demons  seem  to  dominate  the  stage,  although  he  never  succumbed  to  any  obsession with  demonology  of the  kind  which characterized  second  and  third  century  Gnosticism  and  which  was  responsible  for  the  erection  of  a  vast  and  complex  system  of  demonic  hierarchies.  Still,  Climacus  reflects  an  intense  experience  of  demonic  influence,  which  brings  about  splits  and  conflicts  within  man and  impels  him  to  struggle  against  its  divisive  claims.  To split,  to  divert,  to  shift,  to  disrupt is its  essential  procedure;  but  the  struggle is basically  within  man.  Indeed, in the  East  it  is  accepted  that  demons  approach us in the  form  corresponding  to  our  own  inward  state.  Satan  says  to  St. Anthony:  
It is not I who trouble them (the monks),
It is they who trouble themselves.
Thus  demonology  does  in some  measure  signify,  though  it is  not  reducible  to,  psychology.  Nonetheless,  Climacus'  demonological  language  is  at  times  highly  objectified,  pointing,  as  will  be seen,  to real  agents  rather  than  imaginary  shadows.
Demons  are  spirits (pneumata)  or  noetic  beings  (noeroi) which  are  evil  and  whose  main function  is  to  darken  man's  intellect (nous).  Being  spirits,  they  are  more  difficult  to  deal  with  than  human  persons.  They  hate  the  good  and  it  is  they  and  man's  consent  to  them,  not  man  himself,  who  are  the  cause  of  evil.  They  sow  the  seed  of  sin  within  man  and  "force  us to  sin"  but  they  cannot  predict  the  consequences  of  their  sowing,  they  cannot  know  the  future of  our  innermost  thoughts  - except,  as  the  Macarian Homilies  imply,  by  virtue  of  the  fact  that  they  have  been  with  us  for  so  long. But  God  knows (epistatai) that  they  cause  sinful  thoughts  and  that,  at  times,  they  act  without  man's  consent. Their  main  characteristic,  as  will  be  seen  below,  is  judging,  discriminating  against  others  - etymologically diavallein  means  to  slander,  to  throw  over,  to  separate,  to  divide;  in  fact,  people  become  "diabolic"  by  acting  in  this  fashion.   It  seems  that  man, too,  can  become demonized  and  thus  act  against  himself  as  well  as  others.   
Before  examining  some  of  the  ways  in  which  demons  tempt man, one must  note  that  such  expressions  as  "demon  of  despondency"  and  "demon  of  fornication"  indicate  the  aim  of  the  demonic  assaults  rather  than  a  distinction  between  the spirits  as  such.  It  is  this  sense  that  each  demon  can  be  said  to  have  his  particular  function to  fulfill  as  in  a  war.
