In his famous controversy with Celsus attacks were made on Christianity which drew out a defence of the Christian position in which frequent references were made to the secret teachings.[124]
Celsus had alleged, as a matter of attack, that Christianity was a secret system, and Origen traverses this by saying that while certain doctrines were secret, many others were public, and that this system of exoteric and esoteric teachings, adopted in Christianity, was also in general use among philosophers. The reader should note, in the following passage, the distinction drawn between the resurrection of Jesus, regarded in a historical light, and the "mystery of the resurrection."
"Moreover, since he [Celsus] frequently calls the Christian doctrine a secret system [of belief], we must confute him on this point also, since almost the entire world is better acquainted with what Christians preach than with the favourite opinions of
philosophers. For who is ignorant of the statement that Jesus was born of a virgin, and that He was crucified, and that His resurrection is an article of faith among many, and that a general judgment is announced to come, in which the wicked are to be punished according to their deserts, and the righteous to be duly rewarded? And yet the Mystery of the resurrection, not being understood, is made a subject of ridicule among unbelievers. In these circumstances, to speak of the Christian doctrine as a secret system, is altogether absurd. But that there should be certain doctrines, not made known to the multitude, which are [revealed] after the exoteric ones have been taught, is not a peculiarity of Christianity alone, but also of philosophic systems, in which certain truths are exoteric and others esoteric. Some of the hearers of Pythagoras were content with his ipse dixit; while others were taught in secret those doctrines which were not deemed fit to be communicated to profane and insufficiently prepared ears. Moreover, all the Mysteries that are celebrated everywhere throughout Greece and
barbarous countries, although held in secret, have no discredit thrown upon them, so that it is in vain he endeavours to calumniate the secret doctrines of Christianity, seeing that he does not correctly understand its nature."[125]
It is impossible to deny that, in this important passage, Origen distinctly places the Christian Mysteries in the same category as those of the Pagan world, and claims that what is not regarded as a discredit to other religions should not form a subject of attack when found in Christianity.
Still writing against Celsus, he declares that the secret teachings of Jesus were preserved in the Church, and refers specifically to the explanations that He gave to His disciples of His parables, in answering Celsus' comparison of "the inner Mysteries of the Church of God" with the Egyptian worship of animals. "I have not yet spoken of the observance of all that is written in the Gospels, each one of which contains much doctrine difficult to be understood, not merely by the multitude, but even by certain of the more intelligent,
including a very profound explanation of the parables which Jesus delivered to 'those without,' while reserving the exhibition of their full meaning for those who had passed beyond the stage of exoteric teaching, and who came to Him privately in the house. And when he comes to understand it, he will admire the reason why some are said to be 'without,' and others 'in the house.'"[126]
And he refers guardedly to the "mountain" which Jesus ascended, from which he came down again to help "those who were unable to follow Him whither His disciples went." The allusion is to "the Mountain of Initiation," a well-known mystical phrase, as Moses also made the Tabernacle after the pattern "showed thee in the mount."[127] Origen refers to it again later, saying that Jesus showed himself to be very different in his real appearance when on the "Mountain," from what those saw who could not "follow Him on high."[128]
