He is asking everyone to ame three (or more) theological works from the last 25 years (1981-2006) that you consider important and worthy to be included on a list of the most important works of theology of that last 25 years (in no particular order).
I think that traditionalist Orthodox Christians should definitely chime in, in hopes that the people who are replying now, and who will see the published results of this meme will take the time and read traditionalist Orthodox books which perhaps can plant a seed in their hearts so one day they may find themselves converting to Orthodoxy.
An important theological work by a traditional Orthodox Christian from the last 25 years? That's a tough one, since most traditionalists that I've read from that period were busy defending their ecclesiastical situation, not actually write something of important theological value. Orthodox Psychotherapy (1986) by Met. Hierotheos is about the only one I can think of (though he's traditional, not traditionalist). Perhaps you or Anastasios (or someone else) know of some books that I've missed out on though. Out of curiosity, which ones would you nominate?
