You have accomplished the work of the Living Triune God,» wrote His Eminence Metropolitan Seraphim of Piraeus in a congratulatory letter to His Beatitude Patriarch Irenaeus of Serbia, on the occasion of the second proposal (after the Metropolis of Piraeus) to the Primates of the Autocephalous Orthodox Churches for the recognition of the Holy Eighth (879-880 AD) and Ninth (1351 AD) Ecumenical Synods at the future convening of the Pan-Orthodox Synod in 2016.
