The State is only one of the various forms in which national life expresses itself. It is the nation organised for self-protection. And wherever self-protection becomes the supreme need, the State, like Aaron's rod, swallows all the rest. But in many directions, the world has become, or is becoming, international. Science and philosophy, and, to a lesser degree, theology and art, have become the common possession of all civilised nations. The effort to make commerce the expression of international fellowship, with which the name of Cobden is associated, failed, largely as the result of the German policy of high tariffs, but its defeat is only temporary, and the commercial interdependence of nations will reassert its influence when the present phase of international strife is over. The function of the Church is to express the common life and interests of nations, as the State expresses the distinctive character of each. So the Church holds to the four universal things--the authority of Holy Scripture; the Creeds; the two Sacraments, and the historic episcopate. We believe that the retention of the historic Episcopate is essential to the maintenance of the Catholic ideal of the Church. For the bishop is the link between the local and the universal Church; the representative and guardian of the Catholic ideal in the life of the local community; and the representative of the local community in the counsels of the Catholic Church. I have often wished that at least one bishop from some other Church than our own could be associated with the consecration of all bishops of the Anglican Church. For by such association we should bring into clearer prominence the fact that the historic episcopate is more than a national institution. So we reach the final question: What can the Churches do to promote the unity of the nations? An invitation was recently issued by the Archbishop of Upsala for a conference of representatives of the Christian Churches, to reassert, even in this day of disunion, the essential unity of the Body of Christ. For various reasons, such a conference at the present juncture seems impracticable, but the time may come when, side by side with a Congress of the nations, a gathering of representatives of the Churches may be called together to reinforce, by its witness, the idea of international fellowship.
