== Reciting of definitions is (IMHO) inappropriate == 

 It sounds like a grade school assignment to site definition after definition from different dictionaries and encyclopedias.  And it is a citing of secondary sources. 

 I would recommend giving the best definition of theodicy that you can.  If there is so much disagreement that this is impossible, then say that, and give the most pertinent meanings in common usage, with citations to original sources.
