XXVI. Thus also, then, when God is called “a consuming fire,” it is because a name and sign, not of wickedness, but of power, is to be selected. For as fire is the most potent of the elements, and masters all things; so also God is all-powerful and almighty, who is able to hold, to create, to make, to nourish, to make grow, to save, having power of body and soul. As, then, fire is superior to the elements, so is the Almighty Ruler to gods, and powers, and principalities. The power of fire is twofold: one power conduces to the production and maturing of fruits and of animals, of which the sun is the image; and the other to consumption and destruction, as terrestrial fire. When, then, God is called a consuming fire, He is called a mighty and resistless power, to which nothing is impossible, but which is able to destroy.
Respecting such a power, also, the Saviour says, “I came to send fire upon the earth,” indicating a power to purify what is holy, but destructive, as they say, of what is material; and, as we should say, disciplinary. Now fear pertains to fire, and diffusion to light.
XXVII. Now the more ancient men did not write, as they neither wished to encroach on the time devoted to attention bestowed on what they handed down, in the way of teaching, by the additional attention bestowed on writing, nor spent the time for considering what was to be said on writing. And, perhaps convinced that the function of composition and the department of teaching did not belong to the same cast of mind, they gave way to those who had a natural turn for it. For in the case of a speaker, the stream of speech flows unchecked and impetuous, and you may catch it up hastily. But that which is always tested by readers, meeting with strict examination, is thought worthy of the utmost pains, and is, so to speak, the written confirmation of oral instruction, and of the voice so wafted along to posterity by written composition. For that which was committed in trust to the elders, speaking in writing, uses the writer's help to hand itself down to those who are to read it. As, then, the magnet, repelling other matter, attracts iron alone by reason of affinity; so also books, though many read them, attract those alone who are capable of comprehending them. For the word of truth is to some “foolishness,” and to others a “stumbling-block;” but to a few “wisdom.” So also is the power of God found to be. But far from the Gnostic be envy. For it is for this reason also that he asks whether it be worse to give to the unworthy, or not commit to the worthy; and runs the risk, from his abundant love of communicating, not only to every one who is qualified, but sometimes also to one unworthy, who asks importunately; not on account of his entreaty (for he loves not glory), but on account of the persistency of the petitioner who bends his mind towards faith with copious entreaty.
XXVIII. There are those calling themselves Gnostics who are envious of those in their own house more than strangers. And, as the sea is open to all, but one swims, another sails, and a third catches fish; and as the land is common, but one walks, another ploughs, another hunts,— somebody else searches the mines, and another builds a house: so also, when the Scripture is read, one is helped to faith, another to morality, and a third is freed from superstition by the knowledge of things. The athlete, who knows the Olympic stadium, strips for training, contends, and becomes victor, tripping up his antagonists who contend against his scientific method, and fighting out the contest. For scientific knowledge is necessary both for the training of the soul and for gravity of conduct; making the faithful more active and keen observers of things. For as there is no believing without elementary instruction, so neither is there comprehension without science.
XXIX. For what is useful and necessary to salvation, such as the knowledge of the Father, and Son, and Holy Spirit, and also of our own soul, are wholly requisite; and it is at once beneficial and necessary to attain to the scientific account of them. And to those who have assumed the lead in doing good, much experience is advantageous; so that none of the things which appear to be known necessarily and eruditely by others may escape their notice. The exposition, too, of heterodox teaching affords another exercise of the inquiring soul, and keeps the disciple from being seduced from the truth, by his having already had practice beforehand in sounding all round on warlike instruments of music.
XXX. The life of the Gnostic rule, (as they say that Crete was barren of deadly animals,) is pure from every evil deed, and thought, and word; not only hating no one, but beyond envy and hatred, and all evil-speaking and slander.
XXXI. In length of days, it is not on account of his having lived long that the man is to be regarded happy, to whose lot it has also fallen, through his having lived, to be worthy of living for ever. He has pained no one, except in instructing by the word the wounded in heart, as it were by a salutary honey, which is at once sweet and pungent. So that, above all, the Gnostic preserves the decorous along with that which is in accordance with reason. For passion being cut away and stript off from the whole soul, he henceforth consorts and lives with what is noblest, which has now become pure, and emancipated to adoption.
XXXII. Pythagoras thought that he who gave things their names, ought to be regarded not only the most intelligent, but the oldest of the wise men. We must, then, search the Scriptures accurately, since they are admitted to be expressed in parables, and from the names hunt out the thoughts which the Holy Spirit, propounding respecting things, teaches by imprinting His mind, so to speak, on the expressions; that the names used with various meanings, being made the subject of accurate investigation, may be explained, and that that which is hidden under many integuments may, being handled and learned, come to light and gleam forth. For so also lead turns white as you rub it; white lead being produced from black. So also scientific knowledge (gnosis), shedding its light and brightness on things, shows itself to be in truth the divine wisdom, the pure light, which illumines the men whose eyeball is clear, unto the sure vision and comprehension of truth.
XXXIII. Lighting, then, our torch at the source of that light, by the passionate desire which has it for its object, and striving as much as possible to be assimilated to it, we become men full of light, Israelites indeed. For He called those friends and brethren who by desire and pursuit aimed after likeness to the Divinity.
XXXIV. Pure places and meadows have received voices and visions of holy phantasms. But every man who has been perfectly purified, shall be thought worthy of divine teaching and of power.
XXXV. Now I know that the mysteries of science (gnosis) are a laughing-stock to many, especially when not patched up with sophistical figurative language. And the few are at first startled at them; as when light is suddenly brought into a convivial party in the dark. Subsequently, on getting used and accustomed, and trained to reasoning, as if gladdened and exulting for delight, they praise the Lord....For as pleasure has for its essence release from pain; so also has knowledge the removal of ignorance. For as those that are most asleep think they are most awake, being under the power of dream-visions very vivid and fixed; so those that are most ignorant think that they know most. But blessed are they who rouse themselves from this sleep and derangement, and raise their eyes to the light and the truth.
XXXVI. It is, therefore, equally requisite for him who wishes to have a pupil who is docile, and has blended faith with aspiration, to exercise himself and constantly to study by himself, investigating the truth of his speculations; and when he thinks himself right, to descend to questions regarding things contiguous. For the young birds make attempts to fly in the nest, exercising their wings.
