vibrations helps the consciousness to remain in a certain condition, and we naturally find that in the Greek and Roman Catholic Churches the effects produced by the words of the sacrament are greater than these produced in Churches where the words of power are translated. One advantage that comes out of that is that, in the first case, where the priest is using the words that themselves make the vibrations, the man’s character, devotion, and knowledge are not as important as they are in the case where the mechanical effect is lost, and the priest must supply by his own devotion and will-power that which could be more readily produced by the mantra. It is out of that that has come the statement that the unworthiness of the priest does not destroy the worth of the sacrament. Certainly it is not as potent where the priest is unworthy, but where the mechanism is perfect, the worker not being perfect is less important. Now if a clairvoyant watches what is done when a sacrament is taking place, he sees that on the repetition of the words of consecration and the making of the sign of power a visible change occurs in the consecrated object. It is most marked if we turn to the Mass, or Holy Communion. You have there on the altar the sacred elements—the bread and the wine. According to the Roman Catholic doctrine, at the words of power, what is called “transubstantiation” takes place. That teaching has been very much misunderstood by the ordinary Protestant. He does not realise that in every visible object there is an invisible and formative idea; that that idea, working along ordinary lines, produces one of the ordinary objects that you see around you; but that if the idea be changed by the use of a word of power, a mantra, that that change of the idea produces a change of astral matter, and in the etheric and even dense physical matter also a change of vibration is set up. And although it is true that in the densest matter the vibration is not powerful enough to alter the arrangement of the particles, it is true that in all the most important part of that object a change has occurred, and it is that change which is indicated by the word “transubstantiation.” No instructed Roman Catholic ever was foolish enough to think anything save that which I am now putting to you. Now if that idea seems strange, let me remind you of a simple fact which will throw light on the whole thing. Students of organic chemistry are familiar with isometric compounds. Those compounds are made up of exactly the same number of the same chemical elements. Nevertheless, the chemist will tell you that according to the inner arrangement of those elements will be the qualities of the thing. You may have in some of the higher carbon compounds (even so low down as where you have entering into the base only four carbon atoms) an arrangement or rearrangement of those elements such as to give you entirely different qualities—in one case a poison, in the other harmless.
