In thus studying the thought of our time we see that the question of a hidden teaching in connection with Christianity becomes of vital importance. Is Christianity to survive as the religion of the West? Is it to live through the centuries of the future, and to continue to play a part in moulding the thought of the evolving western races? If it is to live, it must regain the knowledge it has lost, and again have its mystic and its occult teachings; it must again stand forth as an authoritative teacher of spiritual verities, clothed with the only authority worth anything, the authority of knowledge. If these teachings be regained, their influence will soon be seen in wider and deeper views of truth; dogmas, which now seem like mere shells and fetters, shall again be seen to be partial presentments of fundamental realities. First, Esoteric Christianity will reappear in the "Holy Place," in the Temple, so that all who are capable of receiving it may follow its lines of published thought; and secondly, Occult Christianity will again descend into the Adytum, dwelling behind the Veil which guards the "Holy of Holies," into which only the Initiate may enter. Then again will occult teaching be within the reach of those who qualify themselves to receive it, according to the ancient rules, those who are willing in modern days to meet the ancient demands, made on all those who would fain know the reality and truth of spiritual things.
Once again we turn our eyes to history, to see whether Christianity was unique among religions in having no inner teaching, or whether it resembled all others in possessing this hidden treasure. Such a question is a matter of evidence, not of theory, and must be decided by the authority of the existing documents and not by the mere ipse dixit of modern Christians.
As a matter of fact both the "New Testament" and the writings of the early Church make the same declarations as to the possession by the Church of such teachings, and we learn from these the fact of the existence of Mysteries—called the Mysteries of Jesus, or the Mystery of the Kingdom—the conditions imposed on candidates, something of the general nature of the teachings given, and other details. Certain passages in the "New Testament" would remain entirely obscure, if it were not for the light thrown on them by the definite statements of the Fathers and Bishops of the Church, but in that light they became clear and intelligible.
It would indeed have been strange had it been otherwise when we consider the lines of religious thought which influenced primitive Christianity. Allied to the Hebrews, the Persians, and the Greeks, tinged by the older faiths of India, deeply coloured by Syrian and Egyptian thought, this later branch of the great religious stem could not do other than again re-affirm the ancient traditions, and place in the grasp of western races the full treasure of the ancient teaching. "The faith once delivered to the saints" would indeed have been shorn of its chief value if, when delivered to the West, the pearl of esoteric teaching had been withheld.
The first evidence to be examined is that of the "New Testament." For our purpose we may put aside all the vexed questions of different readings and different authors, that can only be decided by scholars. Critical scholarship has much to say on the age of MSS., on the authenticity of documents, and so on. But we need not concern ourselves with these. We may accept the canonical Scriptures, as showing what was believed in the early Church as to the teaching of the Christ and of His immediate followers, and see what they say as to the existence of a secret teaching given only to the few. Having seen the words put into the mouth of Jesus Himself, and regarded by the Church as of supreme authority, we will look at the writings of the great apostle S. Paul; then we will consider the statements made by those who inherited the apostolic tradition and guided the Church during the first centuries A.D. Along this unbroken line of tradition and written testimony the proposition that Christianity had a hidden side can be established. We shall further find that the Lesser Mysteries of mystic interpretation can be traced through the centuries to the beginning of the 19th century, and that though there were no Schools of Mysticism recognised as preparatory to Initiation, after the disappearance of the Mysteries, yet great Mystics, from time to time, reached the lower stages of exstasy, by their own sustained efforts, aided doubtless by invisible Teachers.
The words of the Master Himself are clear and definite, and were, as we shall see, quoted by Origen as referring to the secret teaching preserved in the Church. "And when he was alone, they that were about Him with the twelve asked of Him the parable. And He said unto them, 'Unto you it is given to know the mystery of the kingdom of God, but unto them that are without, all these things are done in parables.'" And later: "With many such parables spake He the word unto them, as they were able to hear it. But without a parable spake He not unto them; and when they were alone He expounded all things to His disciples."[41] Mark the significant words, "when they were alone," and the phrase, "them that are without." So also in the version of S. Matthew: "Jesus sent the multitude away, and went into the house; and His disciples came unto Him." These teachings given "in the house," the innermost meanings of His instructions, were alleged to be handed on from teacher to teacher. The Gospel gives, it will be noted, the allegorical mystic explanation, that which we have called The Lesser Mysteries, but the deeper meaning was said to be given only to the Initiates.
Again, Jesus tells even His apostles: "I have yet many things to say to you, but ye cannot bear them now."[42] Some of them were probably said after His death, when He was seen of His disciples, "speaking of the things pertaining to the kingdom of God."[43] None of these have been publicly recorded, but who can believe that they were neglected or forgotten, and were not handed down as a priceless possession? There was a tradition in the Church that He visited His apostles for a considerable period after His death, for the sake of giving them instruction—a fact that will be referred to later—and in the famous Gnostic treatise, the Pistis Sophia, we read: "It came to pass, when Jesus had risen from the dead, that He passed eleven years speaking with His disciples and instructing them."[44] Then there is the phrase, which many would fain soften and explain away: "Give not that which is holy to the dogs, neither cast ye your pearls before swine"[45]—a precept which is of general application indeed, but was considered by the early Church to refer to the secret teachings. It should be remembered that the words had not the same harshness of sound in the ancient days as they have now; for the words "dogs"—like "the vulgar," "the profane"—was applied by those within a certain circle to all who were outside its pale, whether by a society or association, or by a nation—as by the Jews to all Gentiles.[46] It was sometimes used to designate those who were outside the circle of Initiates, and we find it employed in that sense in the early Church; those who, not having been initiated into the Mysteries, were regarded as being outside "the kingdom of God," or "the spiritual Israel," had this name applied to them.
There were several names, exclusive of the term "The Mystery," or "The Mysteries," used to designate the sacred circle of the Initiates or connected with Initiation: "The Kingdom," "The Kingdom of God," "The Kingdom of Heaven," "The Narrow Path," "The Strait Gate," "The Perfect," "The Saved," "Life Eternal," "Life," "The Second Birth," "A Little One," "A Little Child." The meaning is made plain by the use of these words in early Christian writings, and in some cases even outside the Christian pale. Thus the term, "The Perfect," was used by the Essenes, who had three orders in their communities: the Neophytes, the Brethren, and the Perfect—the latter being Initiates; and it is employed generally in that sense in old writings. "The Little Child" was the ordinary name for a candidate just initiated, i.e., who had just taken his "second birth."
When we know this use, many obscure and otherwise harsh passages become intelligible. "Then said one unto Him: Lord, are there few that be saved? And He said unto them: Strive to enter in at the strait gate; for many, I say unto you, will seek to enter in and shall not be able."[47] If this be applied in the ordinary Protestant way to salvation from everlasting hell-fire, the statement becomes incredible, shocking. No Saviour of the world can be supposed to assert that many will seek to avoid hell and enter heaven, but will not be able to do so. But as applied to the narrow gateway of Initiation and to salvation from rebirth, it is perfectly true
