C.H. Spurgeon:

It is not said, “I will feed My sheep one by one,” but, “I will feed My flock.” The Lord has only one flock, and so in this world He has only one Church. “Well,” says one, “we see 20 denominations.” Thank God for it! I am not one of those who would deplore the fact that different Brothers are set for the defense of different parts of the Truth of God. Can you doubt that when Christ prayed that His people might be one, He was heard? It were almost blasphemy to think that His petition was denied! Very well, then, they are one. If the intercession of Christ prevailed, then today the Church is one! I do not believe for a moment that the oneness which Christ intended was ever a oneness of opinion, or a oneness of form of worship any more than a oneness of association, congregating them together in the same building! It was a mystical, secret, vital unity which exists in the Church of God at this very day! Brothers and Sisters, all Believers are really and truly one! When their souls are in a glow with Divine Love, and their hearts speak out of the fullness of their emotion, the unity of the one flock becomes perceptible! The little divisions in the Church of God that challenge your notice are like little cracks upon the surface of the earth—the rock is not cracked. The divisions that we have in the churches are only little skin wounds—the body is not divided. “Not a bone of Him shall be broken.” The great body of Christ still remains indissolubly one! And here tonight, be we Independent, or Baptist, Presbyterian, Episcopalian, or Methodist—if we are one with Christ, we must be one with one another!

After all, the Catholic is right in the expression, while he is wrong in the meaning he attaches to it, when he says there is no salvation out of the pale of the Church. Referred to any worldly policy, it is a lie, but in sober truth, outside of the one indivisible Church of Christ lightly defined, there can be no salvation! But, thanks be unto Christ, every soul that knows the voice of God, the Good Shepherd, and follows at His beck and call, belongs to the one flock, soon to be gathered into the one fold. Note, then, the distinctive and the aggregate description—they are sheep individually and they are, collectively, a flock.
