“Jesus is accused by his enemies of having wrought miracles and shown by his own apostles to have expelled demons by the power of the INEFFABLE NAME. The former firmly believed that he had stolen it in the Sanctuary. “And he cast the spirits with his word…and healed all that were sick” (Matthew 8:16). When the Jewish rulers ask Peter (Acts 4:7), “By what power, or by what name, have ye done this?” Peter replies, “By the NAME of Jesus Christ of Nazareth.” But does this mean the name of Christ, as the interpreters would make us believe; or does it signify, “by the NAME which was in the possession of Jesus of Nazareth”, the initiate, who was accused by the Jews to have learned it but who had it really through initiation? Besides, he states repeatedly that all that he does, he does in “His Father’s Name”, not in his own.
But who of the modern Masons has ever heard it pronounced? In their own Ritual, they confess that they never have. The “Sir Orator” tells the “Sir Knight”, that the passwords which he received in the preceding degrees are all “so many corruptions” of the true name of God engraved on the triangle; and that therefore they have adopted a “substitute” for it. Such also is the case in the Blue Lodge, where the Master, representing King Solomon, agrees with King Hiram that the Word…“shall be used as a substitute for the Master’s word, until wiser ages shall discover the true one.”
What Senior Deacon, of all the thousands who have assisted in bringing candidates from darkness to light; or what Master who has whispered this mystic “word” into the ears of supposititious Hiram Abiffs, while holding them on the five points of fellowship, has suspected the real meaning of even this substitute, which they impart “at low breath”? How few new-made Master Masons but go away imagining that it has some occult connection with the “marrow in the bone.”
What do they know of that mystical personage known to some adepts as the “venerable MAH”, or of the mysterious Eastern Brothers who obey him, whose name is abbreviated in the first syllable of the three which compose the Masonic substitute – the MAH, who lives at this very day in a spot unknown to all but initiates, and the approaches to which are through trackless wilderness, untrodden by Jesuit or missionary foot, for it is beset by dangers fit to appall the most courageous explorers? And yet, for generations this meaningless jingle of vowels and consonants has been repeated in novitiate ears, as though it possessed even so much potency as would deflect from its course, a thistledown floating in the air!”
