29. But that they may know, when they see the word “alone,” that the Son is in no wise to be separated from the Father, let them remember it was said by God in the Prophets: “I stretched forth the heavens alone.” Isa. xliv. 24. The Father certainly did not stretch them forth without the Son. For the Son Himself, Who is the Wisdom of God, says: “When He prepared the heavens I was present with Him.” Prov. viii. 27. And Paul declares that it was said of the Son: “Thou, Lord, in the beginning hast laid the foundation of the earth, and the heavens are the work of Thy hands.” Heb. i. 10. Cf. also Ps. cii. 25. Whether therefore the Son made the heavens, as also the Apostle would have it understood, whilst He Himself certainly did not alone spread out the heavens without the Father; or as it stands in the Book of Proverbs: “The Lord in wisdom hath founded the earth, in understanding hath He prepared the heavens;” Prov. iii. 19. it is proved that neither the Father made the heavens alone without the Son, nor yet the Son without the Father. And yet He who spread out the heavens is said to be alone.
