The work of propagating such truths in parables was left to the disciples of the high Initiates. It was their duty to follow the key‐note of the Secret Teaching without revealing its mysteries. This is shown in the histories of all the great Adepts. Pythagoras divided his classes into hearers of exoteric and esoteric lectures. The Magians received their instructions and were initiated in the far hidden caves of Bactria. When Josephus declares that Abraham taught Mathematics he meant by it “Magic,” for in the Pythagorean code Mathematics mean Esoteric Science, or Gnosis. Professor Wilder remarks: The Essenes of Judæa and Carmel made similar distinctions, dividing their adherents into neophytes, brethren and the perfect.... Ammonius obligated his disciples by oath not to divulge his higher doctrines, except to those who had been thoroughly instructed and exercised [prepared for initiation].(77) One of the most powerful reasons for the necessity of strict secresy is given by Jesus Himself, if one may credit Matthew. For there the Master is made to say plainly: Give not that which is holy unto the dogs, neither cast ye your pearls before swine; lest they trample them under their feet, and turn again and rend you.(78) Profoundly true and wise words. Many are those in our own age, and even among us, who have been forcibly reminded of them—often when too late.(79) Even Maimonides recommends silence with regard to the true meaning of the _Bible_ texts. This injunction destroys the usual affirmation that “Holy Writ” is the only book in the world whose divine oracles contain plain unvarnished truth. It may be so for the learned Kabalists; it is certainly quite the reverse with regard to Christians. For this is what the learned Hebrew Philosopher says: Whoever shall find out the true sense of the Book of _Genesis_ ought to take care not to divulge it. This is a maxim that all our sages repeat to us, and above all respecting the work of the six days. If a person should discover the _true_ meaning of it by himself, or by the aid of another, then he ought to be silent, or if he speaks he ought to speak of it obscurely, in an enigmatical manner, as I do myself, leaving the rest to be guessed by those who can understand me. The Symbology and Esoterism of the _Old Testament_ being thus confessed by one of the greatest Jewish Philosophers, it is only natural to find Christian Fathers making the same confession with regard to the _New Testament_, and the _Bible_ in general. Thus we find Clemens Alexandrinus and Origen admitting it as plainly as words can do it. Clemens, who had been initiated into the Eleusinian Mysteries says, that: The doctrines there taught contained in them _the end of all instructions as they were taken from Moses and the prophets_,
