For, besides the succession of men and the succession of doctrine, there is in her likewise the succession of institutions. As chief of these, but involving a number of subordinate rites, the Apostles with their first oral teaching delivered likewise to the Church sacraments, instituted, not by them, but by their Lord Himself, which at once embodied the truth taught by them, and conveyed the grace by which that truth was to find a home in men’s heart and mind. No sooner was the first teaching of Peter at the head of the Apostles uttered, and the gift of forgiveness of sins and of adoption disclosed, than three thousand persons received the double gift by the baptism which followed. Thus they established in the Church seven great rites, encompassing the whole of human life. The regenerating power which was the beginning of the whole change that they sought to work in man was stored up in one; the confirming and developing it in a second; the feeding and increasing it in a third; the removal of obstacles to it in a fourth; the supporting and restoring the human nature so elevated, when under pressure of sickness and in fear of death, in a fifth; the blessing and consecrating the union of the species in a sixth; and, finally, the conferring that distinctive power which transmitted through all ages her Lord’s gift to the Church in a seventh. This is that great and marvellous sacramental system by which the Church, dowered, as we have said, in her quality of Bride with her Lord’s blood, applies that blood to His members, according to their needs. This is the perpetual consecration of matter to a supernatural end, of which the highest example is found in the Body of the Head Himself, and so it is an enfolding of human nature with the Incarnation, and a transforming it into the image of its Head. But such, likewise, is the summary of the whole written and unwritten teaching of the Church; such also, in few and brief words, the perpetual work of the succession of men whom we have described. Thus the three successions, of men, of doctrines, and of institutions, are woven by the Holy Spirit together as three strands of a rope which cannot be broken: in the union of these three His perpetual presence dwells; and this is the spinal cord whereby He joins the Body with the Head. Let us take instances wherein the force of this union is seen.
