A red light on a railroad tells that there is danger at the spot. Therefore, the outward signs in the Sacraments tell us that there is in the Sacraments something we do not see and which they signify and impart. For example, the outward sign in Baptism is the pouring of the water on the head of the person to be baptized, and the saying of the words. Water is generally used for cleaning purposes. Water, therefore, is used in Baptism as an outward sign to show that as the water cleans the body, so the grace given in Baptism cleans the soul. It is not a mere sign, for at the very moment that the priest pours the water and says the words of Baptism, by the pouring of the water and saying of the words with the proper intention the soul is cleansed from Original Sin; that is, the inward grace is given by the application of the outward sign. Again, in Confirmation the outward sign is the anointing with oil, the Bishop's prayer, and the placing of his hands upon us. Now what inward grace is given in Confirmation? A grace which strengthens us in our faith. Oil, therefore, is used for the outward sign in this Sacrament, because oil gives strength and light. In olden times the gladiators--men who fought with swords as prize-fighters do now with their hands--used oil upon their bodies to make them strong. Oil was used also to heal wounds. Thus in Confirmation the application of this outward sign of strength gives the inward grace of light and strength. Moreover, oil easily spreads itself over anything and remains on it. A drop of water falling on paper dries up quickly; but a drop of oil soaks in and spreads over it. So oil is used to show also that the grace of Confirmation spreads out over our whole lives, and strengthens us in our faith at all times. Again, in Penance we have the outward sign when the priest raises his hand and pronounces over us the words of absolution. If we did not have these outward signs how could anyone know just at what time the graces are given? We can know now, for at the very moment the outward sign is applied the grace is given; because it is the application of the sign that by divine institution gives the grace, and thus the two must take place together. "Institution by Christ" is absolutely necessary because He gives all grace, and He alone can determine the manner in which He wishes it distributed. The Church can distribute His grace, but only in the way He wishes. Hence it cannot make new Sacraments or abolish old ones. 137 Q. How many Sacraments are there? A.
