Now that the Church is broken into pieces, perhaps the first step towards a restoration of true unity is to recognise that there may be real union without unity of external organization. In other words, it is quite possible that Churches which have individually a separate corporate existence--say the Presbyterian, Independent, and Episcopalian Churches--may be one in the New Testament sense. The human race is one; but this unity admits of numberless varieties and diversities in appearance, in colour, in language, and of endless subordinate divisions into races, tribes, and nations. So the Church may be truly one, one in the sense intended by our Lord, one in the _unity of the Spirit_ and the bond of peace, though there continue to be various divisions and sects. It may very well be argued that, constituted as human nature is, the Church, like every other society or institution, will be the better of a competing, if not an opposing, rival; that schism, divisions, sects, are necessary evils; that truth will be more thoroughly investigated, discipline more diligently and justly maintained, useful activities more vigorously engaged in, if there be rival Churches than if there be one. And it is certainly true that, so far as man can foresee, there is no possibility, not to say prospect, of the Church of Christ becoming one vast visible organization. Oneness in that sense is prevented by the very same obstacles that hinder all States and governments on earth from being merged into one great kingdom. But as amidst all diversities of government and customs it is the duty of States to remember and maintain their common brotherhood and abstain from tyranny, oppression, and war, so it is the duty of Churches, however separate in creed or form of government, to maintain and exhibit their unity. If the sects of the Church will frankly and cordially recognise one another as parts of the same whole, if they will exhibit their relationship by combining in good works, by an interchange of ecclesiastical civilities, by aiding one another when aid is needed, this is, I conceive, real union. Certainly Churches which see it to be their duty to maintain a separate existence ought to be equally careful to maintain a real unity with all other Churches.
