The human organism may serve as a type of this. Here is a spiritual being, the Ego, in its will, its thoughts, its affections, invisible, and it makes its presence manifest, and it acts, through the material manifestation and instrument of itself, the body. To believers in God, nature itself, in its deepest reality, is the revelation of the Divine Presence, and the instrument of the Divine action. A beautiful sunset is a veritable and genuine sacrament. In the light of this profound truth, of matter as the manifestation and instrument of spirit, we are enabled to see how futile was the ancient dispute concerning the number of the Sacraments. In view of the fuller and larger knowledge which has come to us, this, like so many other objects of theological strife, ought before this to have been consigned to the limbo of forgotten controversies. But in all this we have been, in fact, interpreting the whole universe in the light of the Incarnation. For that is the supreme sacrament of all, the very type and complete embodiment of the sacramental principle. There we see the Divine manifesting Itself through, and using as the instrument of its action, a Human, a "material" Body. The Eucharist thus for the first time becomes intelligible. It is only one particular illustration, although a most momentous one, of the universal sacramental principle, of which all things else in the world are also illustrations. There we have the Spirit manifesting itself and acting, as always and everywhere, wherever "matter" is found; but in a particular way, and for a particular purpose. The bread and the wine are the material substances which He uses at the critical moments in His perpetual action of feeding us with the flesh and blood of the Son of man. And these elements were obviously chosen, "ordained by Christ Himself," for their most significant symbolism. There is no truer philosophy of the Eucharist than that which is contained in the familiar words of the Church Catechism, which speak of "the strengthening and refreshing of our souls by the Body and Blood of Christ, as our bodies are by the bread and wine." That wonderful, and in itself essentially sacramental process, by which the organism lives by the incorporation and assimilation into its own substance of other substances which we call foods, is the exact analogue of the way in which our true, spiritual manhood lives by the incorporation and assimilation of the manhood of Christ, that manhood which is holy, which exists in the Divine Union, which has perfectly realised eternal life in the complete dying to sin, and the complete putting on of holiness. The Eucharist is, in the broadest sense, the final act in the drama of our salvation. It is the means by which, by His own appointment, all that Christ achieved _for_ us upon the Cross, the repudiation of, or dying to sin, the realisation of perfect obedience, obedience unto death, comes to be _in_ us, is made all our own.
