Were the titles "Son of God" and "Lamb of God" eternal, or did Jesus receive them only at the Incarnation?

Jesus Christ is the eternal Son of God, while the title "Lamb of God" is tied to His eternal plan of salvation accomplished in human history. Scripture distinguishes between His unchanging divine person and the ministry He took upon Himself for our redemption.

The question regarding the titles "Son of God" and "Lamb of God" requires a careful distinction between who Christ is from eternity and what He accomplished in time. The Bible does not teach that the Son was ever created, began to exist, or achieved divinity through birth, baptism, or resurrection. At the same time, His sacrificial ministry as the Lamb became a historical reality through the Incarnation, the cross, and His death for the sins of the world.

The Son of God: An Eternal Person, Not a Created Being

The New Testament does not state that God created the Son and subsequently sent Him, but rather that the Father sent the One who was already His Son. Jesus Himself prayed to the Father about the glory He had before the world existed. This testifies to His preexistence and eternal divine glory.

“And now, Father, glorify me in your presence with the glory I had with you before the world began.” John 17:5

The Gospel of John speaks even more clearly, identifying Christ as the eternal Word: He was with God and was God, and all created things came into being through Him. Therefore, the Son does not belong to the realm of creation; He is the Creator alongside the Father.

“In the beginning was the Word, and the Word was with God, and the Word was God. ... Through him all things were made; without him nothing was made that has been made.” John 1:1–3

The expression "Son of God" does not mean that Christ had a beginning in the way a human son begins to exist after birth. In biblical language, this title reveals His unique, eternal relationship with the Father and His full participation in the divine nature. The apostle Paul calls the Son the image of the invisible God and explains that all things were created in Him.

“The Son is the image of the invisible God, the firstborn over all creation. For in him all things were created: things in heaven and on earth.” Col 1:15–16

The word "firstborn" here does not mean "created." The very next verse explicitly rules out such an interpretation: all of creation came into existence through Him. In Adventist understanding, Christ is the self-existent, eternal God the Son. Ellen White wrote that "in Christ is life, original, unborrowed, underived," emphasizing His full and eternal deity.

The Incarnation Did Not Make Jesus the Son; It Revealed the Son to the World

When the angel told Mary that the Holy One born to her would be called the Son of God, he was not announcing the beginning of the Son’s existence. He was explaining how the eternal Son would enter human history: through a supernatural conception and birth from the Virgin. The One who was the Son prior to the Incarnation also became truly human.

“So the holy one to be born will be called the Son of God.” Luke 1:35

This harmonizes with Paul’s words: God sent forth His Son, and then the Son was born of a woman. The sending of the Son precedes His birth as a human being.

“But when the set time had fully come, God sent his Son, born of a woman, born under the law.” Gal 4:4

Likewise, the resurrection did not make Jesus God’s Son. It powerfully and publicly confirmed His sonship and His victory. Christ did not attain Deity in the resurrection; He rose as the One who was already the Lord of life.

The Lamb of God: An Eternal Purpose and an Accomplished Sacrifice

With the title "Lamb," the case is different. It describes Christ’s specific mission as the Substitute who bears the sin of the world. John the Baptist called Jesus the Lamb even before Calvary, because Christ had already arrived to carry out His appointed ministry.

“Look, the Lamb of God, who takes away the sin of the world!” John 1:29

However, Christ was not literally crucified in eternity. His death occurred once at a specific moment in history. Peter explains that the sacrifice was foreknown before the foundation of the world, but Christ was revealed at the end of the ages for our sake.

“He was chosen before the creation of the world, but was revealed in these last times for your sake.” 1 Pet 1:20

Thus, the phrase about the Lamb "slain from the creation of the world" highlights the absolute certainty of God’s plan of salvation, rather than a continuous or literal crucifixion prior to the creation of the universe. In God’s plan, Calvary was certain from the very beginning; in history, it was realized when Christ gave Himself for humanity.

“All inhabitants of the earth will worship the beast—all whose names have not been written in the Lamb’s book of life, the Lamb who was slain from the creation of the world.” Rev 13:8

The Unity of Eternal Nature and Saving Mission

We must not pit these truths against one another. The eternal Son became man precisely because the love of God sought to save sinners. He did not cease to be God when taking on human nature, nor did He begin to be the Son only in Bethlehem. Yet as the Lamb, He voluntarily embraced the path of suffering, obedience, and death.

“Who, being in very nature God, did not consider equality with God something to be used to his own advantage; rather, he made himself nothing by taking the very nature of a servant, being made in human likeness.” Phil 2:6–7

Conclusion and Practical Application

Jesus is the eternal Son of God: He was not created, nor did He receive His divine nature at the Incarnation. In contrast, the title "Lamb of God" specifically points to His saving mission, planned from eternity and accomplished on the cross. The eternal God the Son drew close to us in human flesh and gave Himself for our sins.

In practical terms, this means we can place our complete trust in Christ. He has the power to save because He is the eternal Lord; He has the desire to save because He is the sacrificial Lamb. Daily embrace His forgiveness, worship Him as God, and imitate His selfless love in the way you treat others.
