But that very sapient fellow Simon makes his statement thus, that there is an indefinite power, and that this is the root of the universe. And this indefinite power, he says, which is fire, is in itself not anything which is simple, as the gross bulk of speculators maintain, when they assert that there are four incomposite elements, and have supposed fire, as one of these, to be uncompounded. Simon, on the other hand, alleges that the nature of fire is twofold; and one portion of this twofold (nature) he calls a something secret, and another (a something) manifest. And he asserts that the secret is concealed in the manifest parts of the fire, and that the manifest parts of the fire have been produced from the secret. And he says that all the parts of the fire, visible and invisible, have been supposed to be in possession of a capacity of perception. The world, therefore, he says, that is begotten, has been produced from the unbegotten fire. And it commenced, he says, to exist thus: The Unbegotten One took six primal roots of the principle of generation from the principle of that fire. For he maintains that these roots have been generated in pairs from the fire; and these he denominates Mind and Intelligence, Voice and Name, Ratiocination and Reflection. And he asserts that in the six roots, at the same time, resides the indefinite power, which he affirms to be Him that stood, stands, and will stand. And when this one has been formed into a figure, He will, according to this heretic, exist in the six powers substantially and potentially. And He will be in magnitude and perfection one and the same with that unbegotten and indefinite power, possessing no attribute in any respect more deficient than that unbegotten, and unalterable, and indefinite power. If, however, He who stood, stands, and will stand, continues to exist only potentially in the six powers, and has not assumed any definite figure, He becomes, says Simon, utterly evanescent, and perishes. And this takes place in the same manner as the grammatical or geometrical capacity, which, though it has been implanted in man's soul, suffers extinction when it does not obtain (the assistance of) a master of either of these arts, who would indoctrinate that soul into its principles. Now Simon affirms that he himself is He who stood, stands, and will stand, and that He is a power that is above all things. So far, then, for the opinions of Simon likewise.

(Hom. lix. 2) Our Lord having reproached the Jews with blindness, they might have said, We are not blind, but we avoid Thee as a deceiver. Our Lord therefore gives the marks which distinguish a robber and deceiver from a true shepherd. First come those of the deceiver and robber: Verily, verily, I say unto you, He that entereth not by the door into the sheepfold, but climbeth up some other way, the same is a thief and a robber. There is an allusion here to Antichrist, and to certain false Christs who had been, and were to be. The Scriptures He calls the door. They admit us to the knowledge of God, they protect the sheep, they shut out the wolves, they bar the entrance to heretics. He that useth not the Scriptures, but climbeth up some other way, i. e. some self-chosen1, some unlawful way, is a thief. Climbeth up, He says, not, enters, as if it were a thief getting over a wall, and running all risks. Some other way, may refer too to the commandments and traditions of men which the Scribes taught, to the neglect of the Law. When our Lord further on calls Himself the Door, we need not be surprised. According to the office which He bears, He is in one place the Shepherd, in another the Sheep. In that He introduces us to the Father, He is the Door; in that He takes care of us, He is the Shepherd.
