The Sacrament of Marriage shows out the marks of a Sacrament as clearly and as definitely as do Baptism and the Eucharist. Both the outer sign and the inward grace are there. The material is the Ring--the circle which is the symbol of the everlasting. The Word of Power is the ancient formula, "In the Name of the Father, and of the Son, and of the Holy Ghost." The Sign of Power is the joining of hands, symbolising the joining of the lives. These make up the outer essentials of the Sacrament. The inner grace is the union of mind with mind, of heart with heart, which makes possible the realisation of the unity of spirit, without which Marriage is no Marriage, but a mere temporary conjunction of bodies. The giving and receiving of the ring, the pronouncing of the formula, the joining of hands, these form the pictorial allegory; if the inner grace be not received, if the participants do not open themselves to it by their wish for the union of their whole natures, the Sacrament for them loses its beneficent properties, and becomes a mere form. But Marriage has a yet deeper meaning; religions with one voice have proclaimed it to be the image on earth of the union between the earthly and the heavenly, the union between God and man. And even then its significance is not exhausted, for it is the image of the relation between Spirit and Matter, between the Trinity and the Universe. So deep, so far-reaching, is the meaning of the joining of man and woman in Marriage. Herein the man stands as representing the Spirit, the Trinity of Life, and the woman as representing the Matter, the Trinity of formative material. One gives life, the other receives and nourishes it. They are complementary to each other, two inseparable halves of one whole, neither existing apart from the other. As Spirit implies Matter and Matter Spirit, so husband implies wife and wife husband. As the abstract Existence manifests in two aspects, as a duality of Spirit and Matter, neither independent of the other, but each coming into manifestation with the other, so is humanity manifested in two aspects--husband and wife, neither able to exist apart, and appearing together. They are not twain but one, a dual-faced unity. God and the Universe are imaged in Marriage; thus closely linked are husband and wife. It is said above that Marriage is also an image of the union between God and man, between the universal and the individualised Spirits. This symbolism is used in all the great scriptures of the world--Hindu, Hebrew, Christian. And it has been extended by taking the individualised Spirit as a Nation or a Church, a collection of such Spirits knit into a unity. So Isaiah declared to Israel: "Thy Maker is thine Husband; the Lord of hosts is His name.... As the bridegroom rejoiceth over the bride, so shall thy God rejoice over thee."[347] So S. Paul wrote that the mystery of Marriage represented Christ and the Church.[348]
