The pure, theistic conception gives at once the pure conception of creation.
Not that the idea of creation can be immediately perceived in the idea of God, which has been shown to be impossible; but that it can be perceived in the idea of God by the medium of the knowledge of finite existences given to the intellect together with the knowledge of infinite being, in the [{2}] primitive intuition. When the idea of infinite being is fully explicated and demonstrated in the perfect conception of God, the existence of real entities which are not God, and therefore not included in necessary being, being known, the relation of these things extrinsic to the being of God, to the being of God itself, becomes evident in the idea of God. It is evident that they have no necessary self-existence either out of the divine being or in the divine being, and therefore have been brought out of nonentity into entity by the act of God.
This creative act of God is that by which he reduces possibility to actuality. It is evident that this possibility of creation, or creability of finite existences extrinsic to the divine essence, is necessary and eternal. For God could not think of doing that which he does not think as possible, and his thoughts are eternal. The thought or idea of creation is therefore eternal in the divine mind. It is a divine and eternal archetype or ideal, which the externised, concrete reality copies and represents. The divine essence is the complete and adequate object of the divine contemplation.
It is, therefore, in his own essence that God must have beheld the eternal possibility of creation and the ground or reason of creability. It is the divine essence itself, therefore, which contains the archetype or ideal of a possible creation. As an archetype, it must contain that which is equivalent to finite essences, capable of being brought into concrete, actual existence by the divine power, and multiplied to an indefinite extent God's eternal knowledge of the possibility of creation is, therefore, his knowledge of his own essence, as an archetype of existences which he is capable of enduing with reality extrinsic to the reality of his own being, by his omnipotent power. The eternal possibility of creation, therefore, exists necessarily in the being and omnipotence of God. It is the imitability of the divine essence as archetype by finite essences, which are its real and extrinsic similitudes, and which are extrinsecated by an act of the divine will. The ideal or archetype of creation is evidently as necessary, as eternal, as unchangeable, as God himself. God cannot create except according to this archetype, and in creating must necessarily copy himself, to give extrinsic existence to something which is a concrete expression of the divine ideal in his own intelligence. This ideal which creation copies being, therefore, eternal in the divine intelligence, and the interior activity of the divine intelligence, or its interior ideal life, being inexplicable except in the relation of the three persons in God, creation is likewise inexplicable, except in relation to the distinct persons of the Trinity.
The Son, or Word, proceeds from the contemplation of his own divine essence by the Father, who thus reproduces the perfect and coequal image of himself. In this act of contemplation, the knowledge of the archetype of creation, or of the creability of essences resembling the divine essence, is necessarily included. The expressed ideal or archetype of all possible existences is therefore in the Word, as the personal image of the Father, and he contains in himself, in an eminent and equivalent manner, infinite similitudes or images capable of being reduced to act, and made to reflect himself in a countless variety of ways. The Son thus communicates with the Father in creative omnipotence. The spiration of the Holy Spirit, from the Father and the Son, consummating the act of contemplation by which the Son is generated in love, and thus completing the interior, intelligent, or spiritual life of God within himself, is perfectly correlated to the eternal generation of the Son. The complete essence of God is communicated by the Father and the Son to the Holy Spirit, and with it creative omnipotence as necessarily included in it. The object of volition in God is identical with the object of intelligence. The essence of God as being the archetype of a possible creation, [{3}] that is, the ideal of creation, or the idea which creation copies, being included in the term of the divine intelligence, or in the Word, is also included in the term of the divine love, or the Holy Spirit. The ideal of creation is therefore included in the object of the eternal, intelligent, living contemplation in which the three persons of the blessed Trinity are united. The power of illimitable creation according to the divine archetype is a necessary and eternal predicate of his divine being, which he contemplates with complacency. The idea of creation is therefore as eternal as God; it is coeval with him, and the object of the ineffable communications of the divine persons with each other from eternity. God has always been pleased with this idea, as the artist delights himself in the ideal of beauty, to which he feels himself capable of giving outward form and expression in sculpture, painting, or architecture.
The decree of God to reduce this possibility of creation to act, or the creative purpose, is likewise eternal; since all divine acts are in eternity, and there is no process of deliberation or progress from equilibrium to determination possible in the unchangeable God. God is actus purissimus, most pure act, and there is in him nothing potential or reducible to act which is not in act from eternity; since in him there is no past or future, and no succession, but tota, simul ac perfecta possessio vitae interminabilss, a complete, simultaneous, and perfect possession of interminable life.
The necessity of his own self-existent being does not determine him to the creative act, but merely to the exercise of supreme omnipotence in choosing freely between the contemplation of creation in its ideal archetype alone, and of creation in its ideal archetype determined to outward actual expression. The inward life of God is necessary, and the interior act of beatific contemplation is of the essence of the divine being. Nothing beyond this, or outside of the interior essence of God, can be necessary, and the creation cannot therefore be necessary, or it would be included in the idea of God, and be identical with the essence of God. God does not create, therefore, by necessity of nature, but by voluntary choice. It is the only exercise of voluntary choice possible to him. It is a choice, however, which though free is determined from eternity. He might have eternally chosen the contrary, that is, to leave the possible creation unactualized in its ideal archetype. He did eternally choose, however, to create.
The learned expositor of St. Thomas, F. Billuart, says that the purpose to create is communicated by the Father to the Word, concomitantly with the intelligence of the divine essence by which he is generated. [Footnote 1] Creation is no afterthought, no capricious or sportive play of omnipotence, like the jeu d'esprit which a poet throws off from a sudden impulse of fancy. The creative purpose has been the theme of the mysterious communications of the three persons of the blessed Trinity, from all eternity. In God, purpose and act, consultation and decree, are one. The decree of creation and the creative act are identical. The creative act, therefore, a parte Dei, is eternal. It is an illusion of the imagination to conceive of time as having existed before creation. "In the beginning, God created the heavens and the earth." That beginning was the first moment of time, which St. Thomas says God created when he created the universe. Time is a mere relation of finite entities to each other and to infinite being, arising from their limitation. The procession of created existences is necessarily in time, and could not have begun ab aeterno without a series actually infinite, which is impossible. Nevertheless, the first instant of created time had no created time behind it, and no series of instants behind it, intervening between it and eternity, but touched immediately on eternity.
