I. THE VINE AND ITS BRANCHES.--_The unity of the vine_. The vine and its branches constitute one plant. Some branches may be trailed along the trellis-work outside the cottage door, others conducted through hothouse after hothouse; yet one life, one stream of sap, one essential quality and character pervades them all, from the dark root, buried in the soil, to the furthest twig or leaf. Yonder branch, waving its fronds high up against the hothouse glass, cannot say to that long leafless branch hidden beneath the shelf, You do not belong to me, nor I to you. No twig is independent of another twig. However different the functions, root and branches, leaves and cluster, all together make one composite but organic whole. So is it with Christ. All who are one with Him are one with each other. The branches that were nearest the root in the days of Pentecost are incomplete without the last converts that shall be added in the old age of the world. Those without these will not be made perfect. This is the underlying truth of the holy Catholic Church. Men have tried to show that it must be an outward and visible organization, consisting of those who had received, through a long line of apostolical succession, some mystic power for administering rites and conferring absolution, together with those who came beneath the touch of their priestly hands. That theory has notoriously broken down. But the truth of which it is a grotesque travesty is presented in our Lord's conception of the vine, deeply planted in the dark grave of Joseph's garden, which had reached down its branches through the ages, and in which every believing soul has a part. Touch Christ, become one with Him in living union, abide in Him, and you are one with the glorious company of the apostles, the goodly fellowship of the prophets, the noble army of martyrs and the Church of the First-born, whose names are written in heaven. _The pliancy of the vine._--More than most plants it needs a husbandman. It cannot stand upright like other fruit-trees, but requires a skillful hand to guide its pliant branches along the espaliers, or to entwine them in the trellis-work. It suggests a true thought of the appearance presented to the world by Christ and His Church. Mrs. Hamilton King, in her description of the sermon preached in the hospital by Ugo Bassi, on the eve of the great movement which, by the expulsion of the Austrians, gave Italy to the Italians, specially dwells on this. Down five wards the prisoners are lying on the hospital-beds from which they will never rise again. To them the deep voice of the hero-preacher tells the story of the vine: how "it is tied to a stake, and if its arms stretch out, it is but cross-wise; they are also forced and bound."
