[T]he origin (arkhê) is not divided up into the All (to pan), for if it were divided up it would destroy the All too; and the All could not any more come into being if the origin did not remain by itself, different from it. Therefore, too, we go back everywhere to one. And in each and every thing there is some one to which you will trace it back, and this in every case to the one before it, which is not simply one, until we come to the simply one; but this cannot be traced back to something else. (tr. Armstrong 1967, 395-397)
The origin or source, for Plotinus, is indeed different (hetéras) from its productions, but this difference or otherness is not ontological, for everything is ultimately traced back and subsists in relation to the One, i.e., all things have the One as the ground of their being (ousia). The division (meros) characteristic of lower entities is not a permanent state, and certainly not one in which personhood is freely developed in relation to God; rather, it is an unstable situation that is only remedied by a contemplative reversion (epistrophê) to the immediate source of one’s being. In the case of the second and third principles, Intellect and World-Soul, their productive and maintaining powers, respectively, are effectual only because they simultaneously proceed from and revert to the absolute One.
Any attempt to come to provide a philosophical explanation of the triune God on the basis of this Platonic system obviously renders Christ and the Spirit ontologically dependent upon the Father, and therefore of lesser rank; and it renders the creation a necessary efflux of God, with no real value apart from its dependence upon the divine ousia. The One’s difference or otherness, in the Platonic-Plotinian schema, is not due to its free act of calling existents out of non-being, but rather to its effortless overflowing of essence. Whereas all beings or hypostases, including the second and third divine principles, susbist by way of their contemplative dependency upon the One, the One itself contemplates and depends upon nothing but itself (cf. Ennead 5.2.1). Herein lies it otherness. Communion and freedom are alike impossible.
Theophilus of Antioch, writing a century before Plotinus, described, through the language and concepts available to him – and to the limited extent that it is possible do so – the inner life of God, which is that of a freely willing creator: “the power of God is shown in this, that, first of all, He creates out of nothing, according to His will, the things that are made” (Ad Autol. 2.13, ANF 2:99). God’s logos and sophia were not, for Theophilus, subordinate hypostases emanating from the Father. We have seen that Theophilus, borrowing a Stoic distinction, conceived of the Logos as the expression of the Father’s internal thoughts, actualized for the purpose of creation. The Spirit (pneuma) he conceived as having a two-fold power or purpose: to hold the cosmos together in a divine embrace, and to penetrate the material realm with a vivifying and maintaining power.
[B]y the Spirit which is borne above the waters, [Moses] means that which God gave for animating the creation, as he gave life to man, mixing what is fine with what is fine. For the Spirit is fine, and the water is fine, that the Spirit may nourish the water, and the water penetrating everywhere along with the Spirit, may nourish creation. For the Spirit being one, and holding the place of light, was between the water and the heaven, in order that the darkness might not in any way communicate with the heaven, which was nearer God, before God said, ‘Let there be light.’ (Ad Autol. 2.13, ANF 2:100)
This is sublime imagery: the Spirit-filled water flowing through the rifts and rills of matter, being carried to every inch of the created realm, giving life and sustenance to all. God, while wholly other, surrounds and penetrates this realm, holding it lovingly in His hand and nourishing it with His Spirit (Ad Autol. 1.7). It is a relation of a proud creator to His glorious creation. Possibly a bit too anthropomorphic for the subtle tastes of Platonic philosophers, but if we pass beyond the poetry to the theological conception, we arrive at a view of God that at once maintains His complete transcendence and otherness, and brings to the fore His intimate relationship with His free creation. The intimate connection between principles that we have seen in the Platonic schema, and which was attractive to Christian theologians, was hereby maintained by Theophilus, yet without sacrificing the purely Christian concept of God as a triune power whose loftiness exceeds human intellectual capacity. “The containing spirit,” writes Theophilus, “is along with the creation contained by the hand of God. As, therefore, the seed of the pomegranate, dwelling inside, cannot see what is outside the rind, itself being within; so neither can man, who along with the whole creation is enclosed by the hand of God, behold God” (Ad Autol. 1.5, ANF 2:90).
