Dialogue is a sure mission, and is faithful to the basics of Orthodoxy.
Working on the rapprochement of the denominations is a natural action of true Orthodoxy. The dialogue among churches is not just a necessity, but it is also duty and faithfulness to Orthodoxy. Orthodoxy is not a wall of separation or high pulpit from which we address the others. Orthodoxy is meek. An Orthodox faithful does not have any special privilege in being Orthodox.
