We believe that Jesus Christ according to His divine nature is the only-begotten Son of God,1begotten from eternity, not made, nor created – for then He would be a creature – but of the same essence with the Father, equally-eternal, who reflects the glory of God and bears the very stamp of His nature (Heb 1:3), and is equal to Him in all things.2He is the Son of God, not only from the time that He assumed our nature but from all eternity,3as these testimonies, when compared with each other, teach us: Moses says that God created the world;4the apostle John says that all things were made by the Word which he calls God.5The letter to the Hebrews says that God made the world through His Son;6likewise the apostle Paul says that God created all things through Jesus Christ.7Therefore it must necessarily follow that He who is called God, the Word, the Son, and Jesus Christ, did exist at that time when all things were created by Him. Therefore He could say, Truly, I say to you, before Abraham was, I am (John 8:58), and He prayed, Glorify Thou Me in Thy own presence with the glory which I had with Thee before the world was made (John 17:5). And so He is true, eternal God, the Almighty, whom we invoke, worship, and serve.
