But we should, I think, be reading the signs of the times amiss if we did not also take account of the fact that there has been growing up lately a new type of corporate personality, not known to history before, and exemplified by your own United States and by the British Empire; the conception of sovereign States linked together in a single life, and exercising therein a joint sovereignty in dealing with those who lie outside the federation, is something of which history bears no record; and we need to try to understand its principle, and see what it is capable of contributing to the life of men in order that we may not fail to use our opportunity, and bring our contribution.[#] [#] See Appendix V. _On Providence in History_. There is our outline sketch of the way in which the history of our own civilisation has grown, within which the Church and Nation are at work. We are members of both. What duty falls upon us as the result of that dual membership? The Christian citizen is called of necessity to fulfil one of three functions—prophet, priest and king. The prophet is one who is called to testify to the ideal unflinchingly, not considering consequences, not perhaps considering ways and means of reaching the ideal, but simply insisting on its nature and calling men and nations to penitence so far as they fail to reach it. It may require more courage than the office of the king or statesman, and yet in itself it is the easiest, because it is relatively simple. In all modern nations, and more so in the degree in which they are democratic, every citizen partakes of the duty of kingship. He has some share in determining how his nation shall act, either in the management of its own internal affairs or in its dealings with other people, and one who has this responsibility and is also a Christian, is involved in the absolute duty of trying to think, and to think with genuine effort, how he may be actually guiding his nation toward the ideal. He must not be content with pious platitudes leading to no action, nor content to consider only his own country’s welfare; but as a member of the Church of Christ which embraces all mankind, he is called to think out and, having thought, to pursue in act the methods by which his nation may genuinely be doing its part to build up the one great Temple of God—His Holy City.
