How does the Trinity relate to Jesus being the Son?

The relationship of the Trinity to Jesus as the Son is fundamental in understanding the Christian doctrine of God. John 1:1-2 emphasizes the preexistence of the Word (Jesus) who was both with God and was God, illustrating the complex relationship within the Trinity. Jesus is not merely assigned the title of Son; rather, He is eternally begotten of the Father, which means His sonship is intrinsic to His being. This eternal relationship underscores the reality that to deny Christ's divinity and His role within the Trinity is to undermine the core of the Christian faith, affecting our grasp of the true nature of God and His redemptive plan.
