No, Hanson and his ELCA minions did not drop the filioque in "ELW". They just added a footnote to the Creed saying that the filioque was a later addition to the Creed, which is true.
There have been recent official dialogues between the Orthodox (SCOBA) and Lutherans (ELCA) and beteen Orthodox and Roman Catholics over the fililoque. Both dialogue groups recommended dropping the filioque. However, at least in the Lutheran-Orthodox dialogue, the Lutheran consensus was to remove the filioque for ecclesiological, historical, and ecumenical reasons, with no theological changes from the "double procession". Thus the "ELW", perhaps perversely, reflects where the leading edge (i.e., NOT the liberal-protestant trailing edge) of ELCA theology is now on that issue.
However, these dialogues, and especially Hanson's running off to occupied Constinople to see the Ecumenical Patriarch from time to time, have done no good in improving the ELCA's standing with the Orthodox.
For the view of the Antiochian Orthodox Church on the ELCA, see http://www.antiochian.org/Orthodox-Lutheran
The lack of theological agreement on the "double procession" and other issues in those dialogues, and especially the ELCA's "full communion" agreements with liberal protestants and its embrace of the "gay" agenda, give the ELCA just about the same standing in the Orthodox world as "TEC"--precisely zero!!!!
Mark Hanson doesn't need to travel to Constantinople or Moscow to find out where he stands. There are at least two fine Orthodox bishops right in Chicagoland where Hanson lives--Serbian Orthodox Metropolitan Christopher (a participant in the Lutheran-Orthodox dialogues) and OCA Archbishop Job. I'm sure that either one of them would be happy to tell Hanson the truth about where he stands, even if he dosn't want to believe the Antiochian statement that he can read on the open Internet.
The Orthodox call doing these things heresy!!!!
