That is a wide-spread and all but universally expressed instinct of human nature. Argue about it as you like, explain it away how you choose, charge the notions of priesthood and sacrifice with exaggeration, immorality, barbarism, if you will--still the thing remains. And I believe for my part that, so far from that want being one which will be left behind, with other rude and savage desires, as men advance in civilisation--it is as real and as permanent as the craving of the understanding for truth, and of the heart for love. When men lose it, it is because they are barbarised, not civilised, into forgetting it. On that rock all systems of religion and eminently all theories of Christianity, that leave out priest and sacrifice, will strike and split. The Gospel for the world must be one which will meet all the facts of man's condition. Chief among these facts is this necessity of the conscience, as expressed by the forms in which for thousands of years the worship of mankind has been embodied all but everywhere--an altar, and a priest standing by its side. I need not pause to remind you how this Jewish people, who have at all events taught the world the purest Theism, and led men up to the most spiritual religion, had this same institution of a priesthood for the very centre of its worship. Nor need I dwell at length on the fact that the New Testament gives--in its full adhesion to the same idea. We are told that all these sacerdotal allusions in it are only putting pure spiritual truth in the guise of the existing stage of religious development--the husk, not the kernel. It seems to me much rather that the Old Testament ceremonial--Temple, priesthood, sacrifice--was established for this along with other purposes, to be a shadow of things to come. Christ's office is not metaphorically illustrated by reference to the Jewish ritual; but the Jewish ritual is the metaphor, and Christ's office the reality. He is the Priest. And what is the priest whom men crave? The first requisite is oneness with those whom he represents. Men have ever felt that one of themselves must fill this office, and have taken from among their brethren their medium of communication with God. And we have a Priest who, 'in all things, is made like unto His brethren,' having taken part of their flesh and blood, and being 'in all points tempted like as we are.' The next requisite is that these men, who minister at earth's altars, should, by some lustration, or abstinence, or white robe, or other external sign, be separated from the profane crowd, and possess, at all events, a symbolic purity--expression of the conviction that a priest must be cleaner and closer to God than his fellows. And we have a Priest who is holy, harmless, undefiled, radiant in perfect purity, lustrous with the light of constant union with God.
