Belgic Confession : Article 10 (2021)

Article 10: The Deity of Christ
We believe that Jesus Christ, according to his divine nature, is the only Son of God-- eternally begotten, not made nor created, for then he would be a creature.
He is one in essence with the Father; coeternal; the exact image of the person of the Father and the "reflection of his glory,"^13 being in all things like him.
He is the Son of God not only from the time he assumed our nature but from all eternity, as the following testimonies teach us when they are taken together.
