After a general introduction I shall refer briefly to some ways in which Friends in the past have made a contribution to the Church’s life and work. I shall then set forth under seven heads the distinctive mission which I believe the Society of Friends has to our own generation both in Western lands and in the awakening nations of the East. In closing we may pause to consider what is required in order that this message may be believed in its fullness and power. I. During the time that I spent in China as a missionary, it was my privilege to be associated with the members of other Christian bodies who were working alongside of Friends in the Province of Szechwan. For a number of years there has been a large measure of co-operation in the missionary work in that province, in some directions of a more thorough character than in any other part of the mission field. The province was mapped out thirteen years ago between the various missions, and by this means overlapping has been avoided and great harmony has prevailed. To such an extent has this been the case that, at the Conference of West China Missions held in Chengtu in 1908, the ideal of “One Protestant Christian Church for West China” was unanimously adopted by a gathering representing the missions of six different denominations, and two inter-denominational societies. It was also resolved “that whereas all Christian missions laboring in West China have for their aim the establishment of the Kingdom of God, and whereas there is a sincere desire for more co-operation and a closer union of our Churches, this Conference recommends the free interchange of full members on a recommendation from the Pastor of the Church from which they come.” This remarkable action on the part of the West China Missionary Conference compelled me to look into the problem suggested by the title of this address in an altogether new way. If we were really working for a single united Church, what was to be the contribution of our Society: had we in fact anything distinctive and vital to give, and in what way were we to give it? The still more remarkable gathering held at Edinburgh in 1910, and the contact which I have since had with members of other Christian bodies in following up the results of that Conference, have pressed the question home with renewed force.
