Very interesting reading with links to:
Opening speech by Arshbishop Christodoulos (Thessaloniki, 1 June 2003)
Certain parts of this speech are very good in my opinion.
Also, there is a letter from the symposium participants to H.B. Patriarch Maximos of Bulgaria and H.B. Catholicos Elias, Patriarch of Georgia.
This letter is a request from the current Orthodox participants that these two Patriarchates rejoin the WCC. Also interesting.
There's also the "final report" on Orthodox involvement in the WCC which will be discussed at the 2006 conference.
