a number of things similar to each other.  If you strike off from a thousand five hundred, or if you strike off nine hundred, there is nothing lost of unity, because there never was unity.  A flock of one thousand or a flock of five is just as much a flock as any other number.

On the other hand, let us turn to the unity of peace which the apostle speaks of, and we find it is something different; it is made up of dissimilar members, without which dissimilarity there could be no unity.  Each is imperfect in itself, each supplying what it has in itself to the deficiencies and wants of the other members.  So, if you strike off from this body any one member, if you cut off an arm, or tear out an eye, instantly the unity is destroyed; you have no longer an entire and perfect body, there is nothing but a remnant of the whole, a part, a portion; no unity whatever.

This will help us to understand the unity of the Church of Christ.  If the ages and the centuries of the Church of Christ, if the different Churches whereof it was composed, if the different members of each Church, were similar—­one in this, that they all held the same views, all spoke the same words, all viewed truth from the same side, they would have no unity; but would simply be an aggregate of atoms, the sand-pit over again—­units, multiplied it may be to infinity, but you would have no real unity, and therefore, no peace.  No unity,—­for wherein consists the unity of the Church of Christ?  The unity of ages, brethren, consists it in this—­that every age is merely the repetition of another age, and that which is held in one is held in another?  Precisely in the same way, that is not the unity of the ages of the Christian Church.

Every century and every age has held a different truth, has put forth different fragments of the truth.  In early ages for example, by martyrdom was proclaimed the eternal sanctity of truth, rather than give up which a man must lose his life....  In our own age it is quite plain those are not the themes which engage us, or the truths which we put in force now.  This age, by its revolutions, its socialisms, proclaims another truth—­the brotherhood of the Church of Christ; so that the unity of ages subsists on the same principle as that of the unity of the human body:  and just as every separate ray—­the violet, the blue, and the orange—­make up the white ray, so these manifold fragments of truth blended together make up the one entire and perfect white ray of Truth.  And with regard to individuals, taking the case of the Reformation, it was given to one Church to proclaim that salvation is a thing received, and not local; to another to proclaim justification by faith; to another the sovereignty of God; to another the supremacy of the Scriptures; to another the right of private judgment, the duty of the individual conscience.  Unite these all, and then you have the Reformation one—­one in spite of manifoldness; those
