Again therefore, let us assume the principles of the science concerning these Gods, and demonstrate that the theory pertaining to them is consequent to the first causes. The intelligible Gods therefore, surpass wholes according to supreme transcendency, and primarily participate the union and divine light, in which all the Gods perfectly establish their hypostases. They likewise unically produce all things from themselves, according to the paternal and exuberant will of the communication of good, and pre-establish in themselves occultly the first effective causes of secondary natures. For the whole and common measures of forms presubsist in them, and they comprehend according to one cause the uniform genera of being, and prior to these, bound and infinity, from which the superessential orders of the Gods generate all beings.
But in the second rank after these, the intelligible and at the same time intellectual Gods subsist, being divided indeed according to the same number, and preserving the measure of the all-perfect triad in a second order, but producing into multitude the unities of intelligibles, and transferring the unical boundaries of those triads into essential hypostases, and which participate of the one. Instead of powers however, which are whole, without separation, and occult, they are transferred into divided causes, and which proceed far from the one.
Again, in the third rank after the intelligible Gods, those that are called intellectual are arranged at one and the same time indeed, proceeding into an order diminished with respect to that which is prior to it, and changing the number according to which they subsist. For instead of the perfective triads, they are intellectually divided according to hebdomads. And with respect to the hebdomads, the division of them into two triads, is supernally derived from the first triads; but the terminations of them into monads, express the ends of those orders. For every thing which is the peculiarity of difference and multitude, proceeds from thence to all the genera.
Again therefore, from these, the multiform orders of the ruling principles are generated, being divided indeed analogous to all the intelligible Gods, and to those that are prior to these intellectual Gods, viz. to those that are called intelligible and at the same time intellectual. They have however, their proximate and peculiar hypostasis from the one fabrication; but their united generation together with intellectuals, from the third triad of intelligibles. For that all-perfect cause produces also from itself, the whole orders of the Gods. Hence likewise Parmenides denominates it infinite multitude, as unfolding into light all the genera of being, and all the orders of divine natures, and as being sufficient through one all-perfect power to the generation of wholes.
Farther still, we may also assert this of these leading and ruling Gods, that the intellectual monads make their progression according to imparticipable intellect, in the same manner as the Gods prior to them illuminate imparticipable life, and prior to all things, the intelligible Gods constitute about themselves truly existing and intelligible essence. For every God is participated indeed by beings, and on this account falls short of the unity which is imparticipable and exempt from all things. But a different deity proceeds according to a different peculiarity. And some of the Gods indeed, being defined according to the ineffable good itself, comprehend the intelligible causes of wholes. But others produce the vivific powers, and connectedly contain the first genera of the Gods. Others again, unfold into light all the intellectual involutions, and preside over the participants of the unities that produce divided hypostases. Since therefore, the intellectual Gods primarily subsist according to imparticipable intellect, and on this account are denominated intellectual, the orders that first proceed immediately after them, illuminate the summit of participated intellect, and are intellectual indeed, as with reference to the inferior orders, and which are now divided according to providential energies about the world. But they are secondary to the first intellectuals, and are allotted a more partial government; just as the first of intellectuals, are indeed intelligible with respect to the Gods produced from them, but fall short of the union of first intelligibles. As therefore, they unfold into light the first and imparticipable life, which the intelligible monads pre-established in themselves according to cause only, and occultly; (for all the causes of wholes are pre-assumed there according to one ineffable union) after the same manner also, these Gods, shining forth the first of the intellectuals, express the Gods from whom they derive their subsistence, and are intellectual indeed, but produce the pure, uniform, and total hyparxis of the fathers, into a secondary, and multiplied progression, which is divided about themselves, and into a diminution of essence. By first emissions also from the first-effective, and self-subsistent fountains, they shine forth similarly to the intellectual Gods.
Hence also, they bind to themselves the ruling and generative causes of all the partial orders, and which exist prior to these orders both in dignity and power. And in short, they have the same transcendency with respect to the other Gods [subordinate to them,] which the intelligible Gods have to those that are produced from them. For the intelligible Gods being expanded above all the intellectual genera, have pre-established the intelligible hyparxis, by itself, unmingled and pure; and these ruling Gods have also established in themselves the supermundane union, and this peculiarity perfectly exempt from mundane natures. And as in the imparticipable and total hypostases, there is indeed, the intelligible genus, itself by itself; there is also the intellectual which is foreign from this; and there is that which is collective of both, which is celebrated as subsisting in the middle, and is denominated intelligible and at the same time intellectual,--thus also, in these partial orders, the peculiarity of the supermundane Gods, pre-exists by itself exempt from the parts of the universe, unco-ordinated with this world, and on all sides comprehending it according to cause.
But the essence of all the mundane Gods is allotted the third order, being proximately carried as in a vehicle in the parts of the world, giving completion to this one and only begotten God, and connectedly-containing the different progressions in it. The government however of the liberated Gods is allotted the middle bond of the extremes, possessing sovereign authority over all [mundane] natures, and in a certain respect communicating with the divisions about the world, but unitedly ascending at the same time into many of its parts, and collecting the divided numbers of the mundane Gods into unical bounds, and more simple causes. Every genus likewise, of the mundane Gods is spread under this liberated order, being on all sides connected, contained, and perfected by it, and filled with the first of goods. If therefore, there is any thing supermundane in the Gods, and if it imparts a certain definite hyparxis of essence to them, and defines a certain peculiarity of powers and a transcendency of order by itself, we must admit that it primarily subsists in the ruling Gods, being derived to them from the intellectual fathers, unmingled with a mundane nature. And this supermundane order indeed is universal, as with reference to all the partible rivers of the Gods, but it is partial, as with reference to the all-perfect, one and whole kingdom of the intellectual Gods. For it is everywhere necessary that the leading causes of secondary orders, should be in a certain respect assimilated to the terminations of the orders established above them.
And thus the progression of the Gods is one and continued, originating supernally from the intelligible and occult unities, and ending in the last division of a divine cause. For, as in sensibles the most gross and solid bodies, are not immediately connascent with the etherial expanse, but those which are simple and more immaterial than others, are proximately spread under the celestial periods, and of containing bodies, those which are primarily contained, are allotted a greater communion than those which are situated remotely, and are conjoined to them through other media; thus also, in the divine essences prior to the world, the second orders are in continuity with those prior to them. The progressions of beings however, are completed through similitude. But the terminations of the higher orders are united to the beginnings of second orders. And one series and indissoluble order, extends from on high, through the surpassing goodness of the first cause, and his unical power. For because indeed, he is one, he is the supplier of union; but because he is the good, he constitutes things similar to him, prior to such as are dissimilar. And thus all things are in continuity with each other. For if this continuity were broken, there would not be union. And things dissimilar to each other being placed in a consequent order, that which is more similar to the principle, would not have a more ancient and honourable progression into being. If therefore, we assert these things rightly, it is necessary that the first hypostases of the partial orders should be total, according to an intellectual transcendency which they are allotted in the divided genera of the Gods, and thus that they should causally comprehend all secondary natures, and conjoin them to the Gods prior to themselves. The order of the ruling Gods therefore, is in continuity with the kingdom of the intellectual Gods. Hence also, Parmenides proximately constitutes it from the demiurgic monad. These things however, will afterwards be apparent.
