Let's treat it as a catechism! In some ways I never graduated from Sunday School, I just continued it at New St. Andrew's and keep up on it with the boys today. That being said, these are Sunday School questions (you really just need to read the Gospel of John). My boys use Hercules Collins catechism, so they could probably answer you. Maybe I'll ask them later.
A: God the Son always existed. From eternity, He is begotten of the Father, not made, and His generation is eternal, without beginning or end. This eternal generation signifies the Son’s essential relationship within the Trinity, proceeding from the Father while remaining of the same divine essence. Scripture declares, “In the beginning was the Word, and the Word was with God, and the Word was God” (John 1:1-2). And Jesus Himself prays, “And now, Father, glorify me in your own presence with the glory that I had with you before the world existed” (John 17:5).
A: He is “light from light,” as the Nicene Creed confesses, emphasizing the Son’s co-eternity with the Father. The Son is not only always light but derives His light from the Father eternally, for He is “the radiance of the glory of God and the exact imprint of his nature” (Hebrews 1:3). This radiant procession affirms that He shares the divine essence fully, yet without any implication of temporal origination. As Jesus declares, “I am the light of the world” (John 8:12). The light He bears is the eternal, uncreated light of God Himself.
A: The Son is the true God from the true God. This confession reflects the eternal procession within the Godhead, whereby the Son derives His divine essence from the Father without division, subordination, or temporality. Jesus Himself testifies to this unity when He says, “I and the Father are one” (John 10:30). The Apostle John affirms, “This is the true God and eternal life” (1 John 5:20). Thus, the Son has always been and will always be the true God, co-equal and consubstantial with the Father.
A: He always existed. To suggest that the Son was produced is to err gravely, falling into heresies such as Arianism, which denies the full divinity of the Son. Scripture testifies that His coming forth is eternal: “But you, O Bethlehem Ephrathah... from you shall come forth for me one who is to be ruler in Israel, whose coming forth is from of old, from ancient days” (Micah 5:2). Moreover, “He is before all things, and in Him all things hold together” (Colossians 1:17). The Son’s existence is eternal, uncaused, and necessary within the triune being of God.
