The will of the Lord in regard to the visible unity of His whole Church is plain: "Other sheep I have which are not of this fold: them also I must lead; and they shall hear My voice, and there shall be one flock, one Shepherd." No doubt there is a difference between a fold ([Greek: anle]) and a flock ([Greek: poimne]), between the racial unity of the Jewish Dispensation and the Catholic and international character impressed from the beginning on the Christian Church. But a flock is as visible as a fold is. We can see the one moving along the road under the shepherd's guidance just as distinctly as we see the other gleaming white on the hillside, or raising its turf-capped walls above the level of the moor. We can see, of course, if the walls of a fold are broken down; but we can see also whether a flock is united, whether it is moving forward as one mass, or is broken up and scattered. Such separations might be well enough if the different little companies were all going quietly on in one way; though even then their breaking up would argue on the one hand a portentous failure in that recognition of the shepherd's voice and the obedience to him which is due to his loving care, and on the other hand a strange lack of that gregariousness which is an instinct in the healthy sheep. But what if the sheep are seen running hither and thither in different directions: if they are found labouring to explain the inadvisability--nay, the impossibility--of their ever coming into line; if we see them instead crossing each other's path, starting from each other, jostling and butting one another, continually getting into situations provocative of fights and injuries? Is this the kind of picture which the Lord Jesus has drawn of His Flock, His Church as He wishes, and intends, that it should be: is this what He promises that it shall be? Christ made His Church one at the beginning: the rulers He set over it "were all with one accord in one place"; "the multitude of them that believed were of one heart and of one soul." And when the Gentiles had been brought in, what care did the Apostles take lest the new departure should cause a separation along a line made obsolete by the Cross of Christ; and with what adoring admiration does St Paul gaze at the delightful spectacle of Jew and Gentile made one new man in Christ Jesus--"where," he cries, "there cannot be Greek and Jew, circumcision and uncircumcision, barbarian, Scythian, bondman, freeman, but Christ is all, and in all."
