(3) But we must, as I think, see from the Oracles the nature of Time and Eternity, for they do not always (merely) call all the things absolutely unoriginated and really everlasting, eternal, but also things imperishable and immortal and unchangeable, and things which are in like fashion, as when they say, "be ye opened, eternal doors," and the like. And often they characterize the things the most ancient by the name of Eternity; and again they call the whole duration of our time Eternity, in so far as the ancient and unchangeable, and the measurement of existence throughout, is a characteristic of Eternity. But they call time that concerned in generation and decay and change, and sometimes the one, and sometimes the other. Wherefore also, the Word of God says that even we, who are bounded here by time, shall partake of Eternity, when we have reached the Eternity which is imperishable and ever the same. But sometimes eternity is celebrated in the Oracles, even as temporal, and time as eternal. But if we know them better and more accurately, things spiritual are spoken of and denoted by Eternity, and things subject to generation by time. It is necessary then to suppose that things called eternal are not absolutely co-eternal with God, Who is before Eternity, but that following unswervingly the most august Oracles, we should understand things eternal and temporal according to the hopes recognized by them, hut whatever participates partly in eternity and partly in time, as things midway between things spiritual and things being born. But Almighty God we ought to celebrate, both as eternity and time, as Author of every time and eternity, and "Ancient of days," as before time, and above time; and as changing appointed seasons and times; and again as being before ages, in so far as He is both before eternity and above eternity and His kingdom, a kingdom of all the Ages. Amen.

(11) The following statement from a modern text book may serve to point to the difference between the conception of Pure Duration, and Time: "Pure Duration is conceived without regard to the motions of changes in things. Time on the contrary is the sensible measure of any portion of duration, often marked by particular phenomena, as the apparent revolution of the celestial bodies, the rotation of the earth on its axis, etc. Our conception of Time originates in that of motions; and particularly in those regular and equable motions carried on in the heavens, the parts of which, from their perfect similarity to each other, are correct measures of the continuous and successive quantity called Time, with which they are conceived to co-exist. Time, therefore, may be defined as, The perceived number of successive movements. Time, based upon the movements of the celestial bodies, or the earth, is frequently measured by instruments based upon such movements, such as watches, clocks, sun-dials, etc." We are also conscious of the passage of Time by changes in our mental states, our thoughts, our mental images, etc., both in the waking state or the state of dreams. Without changes in the outside world, represented to our consciousness by perceptions of such changes, or without changes in our mental states, Time would not exist for us. It thus follows that given an Eternal Changeless Reality, for whom and by whom no "outside world" has been or is manifested; and which is wrapped in an unconscious and dreamless sleep, such as is pictured in the First Aphorism; for such a Reality there could exist no Time—no Time would present itself—Timelessness would abide, until Change began once more.

(4) And for this cause, just as Eternity transcends the bounds of Time; so Time [itself], in that it cannot have bounds set to it by number, or by change, or by the period of the revolution of some second [kind of Time],—is of the nature of Eternity. Both, then, seem boundless, both eternal. And so stability, though naturally fixed, yet seeing that it can sustain the things that are in motion,—because of all the good it does by reason of its firmness, deservedly doth hold the chiefest place. XXXII

(1) God, then, hath [ever] been unchanging, and ever, in like fashion, with Himself hath the Eternity consisted,—having within itself Cosmos ingenerate, which we correctly call [God] Sensible. Of that [transcendent] Deity this Image hath been made,—Cosmos the imitator of Eternity. Time, further, hath the strength and nature of its own stability, in spite of its being in perpetual motion,—from its necessity of [ever] from itself reverting to itself.

(2) And so, although Eternity is stable, motionless, and fixed, still, seeing that the movement of [this] Time (which is subject to motion) is ever being recalled into Eternity,—and for that reason Time’s mobility is circular,—it comes to pass that the Eternity itself, although in its own self, is motionless, [yet] on account of Time, in which it is—(and it is in it),—it seems to be in movement as all motion. So that it comes to pass, that both Eternity’s stability becometh moved, and Time’s mobility becometh stable. So may we ever hold that God Himself is moved into Himself by [ever-] same transcendency of motion. For that stability is in His vastness motion motionless; for by His vastness is [His] law exempt from change.

(10) The First Aphorism further states: "Time there was not: for Change had not begun." Here, again, is expressed another "hard saying" for the student who has not grasped the true meaning of "Time." Time, in the strict philosophical meaning of the term, does not mean pure duration of existence —instead, it means "the measure of changing existence." An enduring existence in which there is no change of form, activity, or degree, mental or physical, is Timeless. Time, in fact, is but the "measure of Change." Without Change there can be no Time, in the true sense of the latter term. Pure Being manifests not Time. Time is the result of Becoming, or Change, and is always measured by change or becoming in something.

(10) The Pre-existing then is beginning and end of existing things; beginning indeed as Cause, and end as for whom; and term of all, and infinitude of all infinitude; and term, especially, of things that are, as it were, opposed. For in One, as we have often said, He both pre-holds and sustains all existing things, being present to all, and everywhere, both as regards the one, and the same, and as the every same, and issuing forth to all, and abiding in Himself; and standing and moving, and neither standing nor moving; neither having beginning, or middle, or end; neither in any of the existing things, nor being any of the existing things. And neither does any of the things eternally existing, or those temporarily subsisting, entirely come up to Him, but He towers above time and eternity, and all things eternal and temporal. Wherefore also, He is Eternity itself, and things existing, and the measures of things existing, and things measured through Him and from Him. But let us speak of these things more opportunely on another occasion.

(2) Eternity, for instance, presents in an instant the future and the present, also the past of time. But truth, much more powerful than limitless duration, can collect its proper germs, though they have fallen on foreign soil. For we shall find that very many of the dogmas that are held by such sects as have not become utterly senseless, and are not cut out from the order of nature (by cutting off Christ, as the women of the fable dismembered the man), though appearing unlike one another, correspond in their origin and with the truth as a whole. For they coincide in one, either as a part, or a species, or a genus. For instance, though the highest note is different from the lowest note, yet both compose one harmony. And in numbers an even number differs from an odd number; but both suit in arithmetic; as also is the case with figure, the circle, and the triangle, and the square, and whatever figures differ from one another.

(12) Therefore, the student will perceive the necessary truth of the statement of the First Aphorism that for the Eternal Parent, wrapped in the Sleep of the Cosmic Night, "Time there was not: for Change had not begun." It is impossible to hold otherwise, considering the nature of Time, and the absence of Change during the Cosmic Night of the Eternal Parent. The student will perceive that given Infinite Existence, and the absence of Change, then we must necessarily postulate Pure Duration, and the absence of Time. There is no logical escape from this conclusion.

(2) Mind: Hear [then], My son, how standeth God and All. God; Aeon; Cosmos; Time; Becoming. God maketh Aeon; Aeon, Cosmos; Cosmos, Time; and Time, Becoming The Good - the Beautiful, Wisdom, Blessedness - is essence, as it were, of God; of Aeon, Sameness; of Cosmos, Order; of Time, Change; and of Becoming, Life and Death. The energies of God are Mind and Soul; of Aeon, lastingness and deathlessness; of Cosmos, restoration and the opposite thereof; of Time, increase and decrease; and of Becoming, quality. Aeon is, then, in God; Cosmos, in Aeon; in Cosmos; Time; in Time, Becoming. Aeon stands firm round God; Cosmos is moved in Aeon; Time hath its limits in the Cosmos; Becoming doth become in Time.

(37) Timaeus: still more closely. Accordingly, seeing that that Model is an eternal Living Creature, He set about making this Universe, so far as He could, of a like kind. But inasmuch as the nature of the Living Creature was eternal, this quality it was impossible to attach in its entirety to what is generated; wherefore He planned to make a movable image of Eternity, and, as He set in order the Heaven, of that Eternity which abides in unity He made an eternal image, moving according to number, even that which we have named Time.

(37) Timaeus: For simultaneously with the construction of the Heaven He contrived the production of days and nights and months and years, which existed not before the Heaven came into being. And these are all portions of Time; even as “Was” and “Shall be” are generated forms of Time, although we apply them wrongly, without noticing, to Eternal Being. For we say that it “is” or “was” or “will be,” whereas, in truth of speech, “is” alone
