That is almost exactly the same language as "proposition one" of the ELCA Task Farce, which is coming up for a vote in Orlando this August. This calls us to learn to live together despite our disagreements, for the sake of "unity in Christ" and the ELCA's "mission".
But REAL unity in Christ is Trinitarian and sacramental, and means being one with each other "as the Father and I are one". This has to do with theosis/divinization/sanctification, NOT stifling of the views of orthodox believers for the sake of "unity" with gnostics and antinomians!!!! "Proposition one" is, like the other two propositions, a bunch of anti-Christian hooey!!
By the way, my Serbian Orthodox congregation (including I) will be celebrating Vidovdan, the observance of the 1389 Battle of Kosovo, this Sunday. (The actual date is the 28th.) So Anglicans and Lutherans on this list should remember our Serbian Orthodox Christian brothers and sisters in prayer this Sunday, aloud during the prayer of the church in the liturgy if possible!
In 1998, during Clinton's little diversion, I read up on that. Didn't know much about the Balkans before then except that the Nazi's in WWII got a number of black eyes there. When I learned the history behind Kosovo, I knew that we were (are?) on the wrong side. I will remember that in my prayers this Sunday.
