127. The Nicene Doctrine of the Consubstantiality of the Son with the Father. (Chapter 9. Theology; the Development of Ecumenical Orthodoxy.) (History of the Christian Church) (Schaff, Philip)

Comp. the literature in 119 and 120, especially the four Orations of Athanasius against the Arians, and the other anti-Arian tracts of this father of orthodoxy.

The Nicene, Homo-ousian, or Athanasian doctrine was most clearly and powerfully represented in the East by Athanasius, in whom it became flesh and blood;1 and next to him, by Alexander of Alexandria, Marcellus of Ancyra (who however strayed into Sabellianism), Basil, and the two Gregories of Cappadocia; and in the West by Ambrose and Hilary.

The central point of the Nicene doctrine in the contest with Arianism is the identity of essence or the consubstantiality of the Son with the Father, and is expressed in this article of the (original) Nicene Creed: [We believe] in one Lord Jesus Christ, the Son of God; who is begotten the only-begotten of the Father; that is, of the essence of the Father, God of God, and Light of Light, very God of very God, begotten, not made, being of one substance with the Father.

The term o Jmoouvsio, consubstantial, is of course no more a biblical term,1 than trinity;1 but it had already been used, though in a different sense, both by heathen writers1 and by heretics,1 as well as by orthodox fathers. It formed a bulwark against Arians and Semi-Arians, and an anchor which moored the church during the stormy time between the first and the second ecumenical councils. At first it had a negative meaning against heresy; denying, as Athanasius repeatedly says, that the Son is in any sense created or produced and changeable. But afterwards the homoousion became a positive testword of orthodoxy, designating, in the sense of the Nicene council, clearly and unequivocally, the veritable and essential deity of Christ, in opposition to all sorts of apparent or half divinity, or mere similarity to God. The same divine, eternal, unchangeable essence, which is in an original way in the Father, is, from eternity, in a derived way, through generation, in the Son; just as the water of the fountain is in the stream, or the light of the sun is in the ray, and cannot be separated from it. Hence the Lord says: I am in the Father, and the Father in Me; He that has seen Me has seen the Father; I and My Father are one. This is the sense of the expression: God of God, very God of very God. Christ, in His divine nature, is as fully consubstantial with the Father, as, in His human nature, He is with man; flesh of our flesh, and bone of our bone; and yet, with all this, He is an independent person with respect to the Father, as He is with respect to other men. In this view Basil turns the term o Jmoouvsio against the Sabellian denial of the personal distinctions in the Trinity, since it is not the same thing that is consubstantial with itself, but one thing that is consubstantial with another. Consubstantiality among men, indeed, is predicated of different individuals who partake of the same nature, and the term in this view might denote also unity of species in a tritheistic sense.

But in the case before us the personal distinction of the Son from the Father must not be pressed to a duality of substances of the same kind; the homoousion, on the contrary, must be understood as identity or numerical unity of substance, in distinction from mere generic unity. Otherwise it leads manifestly into dualism or tritheism. The Nicene doctrine refuses to swerve from the monotheistic basis, and stands between Sabellianism and tritheism; though it must be admitted that the usage of oujsiva and u Jpovstasi"_ still wavered for a time, and the relation of the consubstantiality to the numerical unity of the divine essence did not come clearly out till a later day. Athanasius insists that the unity of the divine essence is indivisible, and that there is only one principle of Godhead. He frequently illustrates the relation) as Tertullian had done before him, by the relation between fire and brightness,1 or between fountain and stream; though in these illustrations the proverbial insufficiency of all similitudes must never be forgotten. We must not, says he, take the words in John xiv. 10: 'I am in the Father and the Father in Me' as if the Father and the Son were two different interpenetrating and mutually complemental substances, like two bodies which fill one vessel. The Father is full and perfect, and the Son is the fulness of the Godhead. We must not imagine, says he in another place, three divided substances1 in God, as among men, lest we, like the heathen, invent a multiplicity of gods; but as the stream which is born of the fountain, and not separated from it, though there are two forms and names. Neither is the Father the Son, nor the Son the Father; for the Father is the Father of the Son, and the Son is the Son of the Father. As the fountain is not the stream, nor the stream the fountain, but the two are one and the same water which flows from the fountain into the stream; so the Godhead pours itself, without division, from the Father into the Son. Hence the Lord says: I went forth from the Father, and come from the Father. Yet He is ever with the Father, He is in the bosom of the Father, and the bosom of the Father is never emptied of the Godhead of the Son.

The Son is of the essence of the Father, not by division or diminution, but by simple and perfect self-communication. This divine self-communication of eternal love is represented by the figure of generation, suggested by the biblical terms Father and Son, the only-begotten Son, the firstborn. The eternal generation is an internal process in the essence of God, and the Son is an immanent offspring of this essence; whereas creation is an act of the will of God, and the creature is exterior to the Creator, and of different substance. The Son, as man, is produced;1 as God, he is unproduced or uncreated;1 he is begotten1 from eternity of the unbegotten1 Father. To this Athanasius refers the passage concerning the Only-begotten who is in the bosom of the Father.

Generation and creation are therefore entirely different ideas. Generation is an immanent, necessary, and perpetual process in the essence of God himself, the Father's eternal communication of essence or self to the Son; creation, on the contrary, is an outwardly directed, free, single act of the will of God, bringing forth a different and temporal substance out of nothing. The eternal fatherhood and sonship in God is the perfect prototype of all similar relations on earth. But the divine generation differs from all human generation, not only in its absolute spirituality, but also in the fact that it does not produce a new essence of the same kind, but that the begotten is identical in essence with the begetter; for the divine essence is by reason of its simplicity, incapable of division, and by reason of its infinity, incapable of increase. The generation, properly speaking, has no reference at all to the essence, but only to the hypostatical distinction. The Son is begotten not as God, but as Son, not as to his natura, but as to his ijdiovth, his peculiar property and his relation to the Father. The divine essence neither begets, nor is begotten. The same is true of the processio of the Holy Ghost, which has reference not to the essence, but only to the person, of the Spirit. In human generation, moreover, the father is older than the son; but in the divine generation, which takes place not in time, but is eternal, there can be no such thing as priority or posteriority of one or the other hypostasis. To the question whether the Son existed before his generation, Cyril of Alexandria answered: The generation of the Son did not precede his existence, but he existed eternally, and eternally existed by generation. The Son is as necessary to the being of the Father, as the Father to the being of the Son.

The necessity thus asserted of the eternal generation does not, however, impair its freedom, but is intended only to deny its being arbitrary and accidental, and to secure its foundation in the essence of God himself. God, to be Father, must from eternity beget the Son, and so reproduce himself; yet he does this in obedience not to a foreign law, but to his own law and the impulse of his will. Athanasius, it is true, asserts on the one hand that God begets the Son not of his will,1 but by his nature,1 yet on the other hand he does not admit that God begets the Son without will,1 or of force or unconscious necessity. The generation, therefore, rightly understood, is an act at once of essence and of will. Augustine calls the Son will of will. In God freedom and necessity coincide.

The mode of the divine generation is and must be a mystery. Of course all human representations of it must be avoided, and the matter be conceived in a purely moral and spiritual way. The eternal generation, conceived as an intellectual process, is the eternal self-knowledge of God; reduced to ethical terms, it is his eternal and absolute love in its motion and working within himself.

In his argument for the consubstantiality of the Son, Athanasius, in his four orations against the Arians, besides adducing the proof from Scripture, which presides over and permeates all other arguments, sets out now in a practical method from the idea of redemption, now in a speculative, from the idea of God.

Christ has delivered us from the curse and power of sin, reconciled us with God, and made us partakers of the eternal, divine life; therefore he must himself be God. Or, negatively: If Christ were a creature, he could not redeem other creatures from sin and death. It is assumed that redemption is as much and as strictly a divine work, as creation.

Starting from the idea of God, Athanasius argues: The relation of Father is not accidental, arising in time; else God would be changeable;1 it belongs as necessarily to the essence and character of God as the attributes of eternity, wisdom, goodness, and holiness; consequently he must have been Father from eternity, and this gives the eternal generation of the Son. The divine fatherhood and sonship is the prototype of all analagous relations on earth. As there is no Son without Father, no more is there Father without Son. An unfruitful Father were like a dark light, or a dry fountain, a self-contradiction. The non-existence of creatures, on the contrary, detracts nothing from the perfection of the Creator, since he always has the power to create when he will. The Son is of the Father's own interior essence, while the creature is exterior to God and dependent on the act of his will. God, furthermore, cannot be conceived without reason (a[logo ), wisdom, power, and according to the Scriptures (as the Arians themselves concede) the Son is the Logos, the wisdom, the power, the Word of God, by which all things were made. As light rises from fire, and is inseparable from it, so the Word from God, the Wisdom from the Wise, and the Son from the Father. The Son, therefore, was in the beginning, that is, in the beginning of the eternal divine being, in the original beginning, or from eternity. He himself calls himself one with the Father, and Paul praises him as God blessed forever.

Finally Christ cannot be a proper object of worship, as he is represented in Scripture and has always been regarded in the Church, without being strictly divine. To worship a creature is idolatry.

When we attentively peruse the warm, vigorous, eloquent, and discriminating controversial writings of Athanasius and his co-laborers, and compare with them the vague, barren, almost entirely negative assertions and superficial arguments of their opponents, we cannot escape the impression that, with all their exegetical and dialectical defects in particulars, they have on their side an overwhelming preponderance of positive truth, the authority of holy Scripture, the profounder speculations of reason, and the prevailing traditional faith of the early church.

The spirit and tendency of the Nicene doctrine is edifying; it magnifies Christ and Christianity. The Arian error is cold and heartless, degrades Christ to the sphere of the creature, and endeavors to substitute a heathen deification of the creature for the true worship of God. For this reason also the faith in the true and essential deity of Christ has to this day an inexhaustible vitality, while the irrational Arian fiction of a half-deity, creating the world and yet himself created, long ago entirely outlived itself.
