XII. Comparing the Call of Isaiah and the Baptismal Commissioning of Jesus

Isaiah’s call and Jesus’ baptism stand as two of the most theologically rich commissioning moments in all of Scripture. Both occur at turning points in salvation history: Isaiah’s call (Isa. 6) comes at the end of King Uzziah’s reign, signaling impending judgment and the need for prophetic clarity; Jesus’ baptism (Matt. 3; Mark 1; Luke 3; John 1) inaugurates His public ministry and the fulfillment of messianic prophecy. In both scenes, the heavens open to reveal the divine will. Isaiah sees the Lord “high and lifted up” with seraphim crying, “Holy, holy, holy” (Isa. 6:1–3), while Jesus sees the Spirit descending “like a dove” and hears the voice of the Father declaring, “This is my beloved Son, with whom I am well pleased” (Matt. 3:17). Each vision reveals a Trinitarian dimension: Isaiah’s vision implies divine majesty and purification; Jesus’ baptism explicitly manifests Father, Son, and Holy Spirit.

The structure of each moment also emphasizes mission through consecration. Isaiah is purified with a burning coal from the altar a painful yet grace-filled preparation for his prophetic role. Jesus, though sinless, humbles Himself to be baptized by John “to fulfill all righteousness” (Matt. 3:15). Where Isaiah is cleansed before being sent, Jesus is revealed as already pure and yet chooses to descend into the waters as a sign of solidarity with sinful humanity. As Brant Pitre observes, “Jesus’ baptism is not for His sake but for ours He steps into the place of sinners to transform baptism into a sacrament of divine adoption.”[29] Isaiah responds, “Here I am! Send me,” while Jesus emerges from the water already on the path to the cross. Both begin their mission immediately following divine encounter, and both will proclaim a message that will be heard by some and rejected by many.

Yet the most striking contrast lies in the fruit of their mission. Isaiah is sent to preach to a people whose hearts will grow dull, eyes blind, and ears deaf (Isa. 6:9–10). His faithfulness is met with resistance and martyrdom. Jesus, too, will be rejected but He will also heal the deaf, open blind eyes, and raise the dead, reversing the judgment that Isaiah could only announce. As John’s Gospel affirms, “Though he had done so many signs before them, they still did not believe in him, so that the word spoken by the prophet Isaiah might be fulfilled” (John 12:37–38). Isaiah prefigures Christ; Christ fulfills Isaiah. One sees the throne from afar; the other steps down from it. Both are servants, but only one is the Son.

The way the two calls tie together. Jesus’ baptism makes baptism of divine adoption. Significant, easy to brush past. God spoke from the heavens, in whom I’m well pleased. Desire of the hearts, long to belong.

XIII. Comparing the Response of Contemporaries to Isaiah and Jesus

Both Isaiah and Jesus were faithful messengers sent to a resistant people and both were put to death for proclaiming the truth. Isaiah was commissioned to speak to Judah in a time of religious corruption and political crisis, and God warned him from the start that his message would fall on deaf ears: “Keep on hearing, but do not understand” (Isa. 6:9). His prophecies though beautiful, poetic, and full of divine vision called out the sins of the nation and its leaders. According to ancient Jewish tradition preserved in the Martyrdom of Isaiah and alluded to in Hebrews 11:37, Isaiah was sawn in two under the wicked King Manasseh, a violent death borne of his unflinching obedience. His contemporaries did not tolerate the word of God when it cut too close to the heart.

Jesus, likewise, began His public ministry amid great expectation and spiritual distortion. Though many initially followed Him for His teaching and miracles, Jesus’ consistent call to repentance, His critiques of religious leaders, and His claim to divine authority provoked opposition. As John’s Gospel makes clear, the widespread rejection of Jesus fulfilled Isaiah’s own words: “He has blinded their eyes and hardened their heart” (John 12:40). Ultimately, like Isaiah, Jesus was condemned and executed not by accident, but as the culmination of His prophetic and redemptive mission. Yet unlike Isaiah, Jesus’ death was not only martyrdom it was atonement, but a voluntary offering also that reconciled the world to God.

Thus, while both were prophets rejected by their generation and killed for their obedience, the fruit of their missions diverges in kind and scope. Isaiah’s word revealed sin and pointed toward future redemption. Jesus’ word accomplished redemption and exposed sin to the light of mercy. Both unveil the human tendency to resist the truth, but both also show that God’s word is never wasted. In the divine pedagogy, even rejection becomes seed. Isaiah’s blood was the price of truth preserved; Jesus’ blood was the price of salvation made present.

Death not the end, where is the sting. Comfort of all who face death.
