Peace subsists not between things exactly alike. We do not speak of peace in a single country. We say peace subsists between different countries where war _might_ be. There can be no _peace_ between two men who agree in everything; peace subsists between those who differ. There is no peace between Baptist and Baptist; so far as they are Baptists, there is perfect accordance and agreement. There may be peace between you and the Romanist, the Jew, or the Dissenter, because there are angles of sharpness which might come into collision if they were not subdued and softened by the power of love. It was given to the Apostle Paul to discern that this was the ground of unity. In the Church of Christ he saw men with different views, and he said So far from that variety destroying unity, it was the only ground of unity. There are many doctrines, all of them different, but let those varieties be blended together--in other words, let there be the peace of love, and then you will have unity.
Once more this unity, whereof the apostle speaks, consists in submission to one single influence or spirit. Wherein consists the unity of the body? Consists it not in this,--that there is one life uniting, making all the separate members one? Take away the life, and the members fall to pieces: they are no longer one; decomposition begins, and every element separates, no longer having any principle of cohesion or union with the rest.
There is not one of us who, at some time or other, has not been struck with the power there is in a single living influence. Have we never for instance, felt the power wherewith the orator unites and holds together a thousand men as if they were but one; with flashing eyes and throbbing hearts, all attentive to his words, and by the difference of their attitudes, by the variety of the expressions of their countenances testifying to the unity of that single living feeling with which he had inspired them? Whether it be indignation, whether it be compassion, or whether it be enthusiasm, that one living influence made the thousand for the time, one. Have we not heard how, even in this century in which we live, the various and conflicting feelings of the people of this country were concentrated into one, when the threat of foreign invasion had fused down and broken the edges of conflict and variance, and from shore to shore was heard one cry of terrible defiance, and the different classes and orders of this manifold and mighty England were as one? Have we not heard how the mighty winds hold together, as if one, the various atoms of the desert, so that they rush like a living thing, across the wilderness? And this, brethren, is the unity of the Church of Christ, the subjection to the one uniting spirit of its God.
