Big Idea: Jesus, at last recognized as the Messiah, speaks of his own rejection and death but then is revealed in glory.
Understanding the Text
This is the climax to the christological theme that has been developing through the first part of the Gospel: the question “Who is this?” now receives two definitive answers, one from the human witness Peter (“God’s Messiah”), the other from God himself (“my Son”). Here too is the answer to John the Baptist’s question in 7:19. But Peter’s acclamation leads, to the reader’s surprise, to a declaration by Jesus that the Messiah’s mission is to suffer and die, before being raised to life again. This will now become the central theme of the Gospel, as Jesus repeats the warning at intervals (9:43–45; 13:31–35; 14:25–27; 17:25; 18:31–34). His determined progress toward Jerusalem to meet his fate will provide the framework of the story from 9:51.
The revelation of Jesus’s glory on the mountain stands out as a unique experience for the disciples. It provides the reader with a reassuring glimpse behind the scenes, a “moment of truth,” to offset the dark events to come. God’s repetition of his testimony to Jesus, first given at his baptism (3:22), gives the reader a theological background against which to interpret what follows.
Historical and Cultural Background
On the meaning of “messiah,” see the sidebar “The Messiah.”
The ascent of a mountain with three chosen companions recalls Moses at Sinai (Exod. 24). That same passage also speaks of God’s glory seen in a cloud on the mountain, into which Moses entered; cloud and bright light are understood as signs of God’s presence in the Old Testament.
Interpretive Insights
9:18 Once when Jesus was praying in private. This is a typical situation in Luke; compare 11:1, when again the disciples are present. Note that the revelations of 9:18–20, 28–36 both occur in the context of Jesus’s prayer. Luke does not mention the location near Caesarea Philippi, north of Galilee (so Mark and Matthew).
9:19 Some say John the Baptist. The answer echoes the popular opinions mentioned in 9:7–8; see comments there.
9:20 Peter answered, “God’s Messiah.” To see Jesus as a prophet, as the people did, placed him on a level with many other prophets in the Old Testament and since. Peter’s insight is that Jesus is unique. There was to be only one Messiah (see the sidebar “The Messiah”). The reader already knows that Jesus is the Messiah (2:11, 26; 4:41); now the disciples have caught up.
9:21 not to tell this to anyone. This surprising reticence is probably best explained by the likely connotations of the term “messiah” for the popular mind (and possibly also in Peter’s intention; cf. Mark 8:30–33). The mission that Jesus goes on to outline is diametrically opposed to any notion of the triumphant expulsion of the Roman armies, and he does not want to stir up such misleading hopes (or give a political handle to his enemies) before his paradoxical mission has been accomplished. He is the Messiah, but not that sort of messiah.
9:22 The Son of Man must. On this term, see the sidebar “The Son of Man” at 5:12–26. Its use here, as a deliberate substitute for Peter’s term “Messiah,” is designed to avoid the potentially misleading connotations of that title and to allow Jesus to set his own, unexpected agenda.
the elders, the chief priests and the teachers of the law. These three groups together made up the Sanhedrin in Jerusalem, the official representatives of the Jewish people. This is therefore a formal rejection of the Jewish Messiah by the Jewish leadership.
he must be killed and on the third day be raised to life. Here and in 18:33 Jesus links resurrection to his predicted death. In 24:6–8 the women will be expected to remember this prediction, but it is clear in 24:11–12 and in the Emmaus story that the disciples had not grasped it.
9:23 take up their cross daily. Jesus has not specified crucifixion as such, but Jews knew what form Roman execution was likely to take. So “take up the cross” meant to face the prospect of a shameful death. Luke’s addition of “daily” suggests that he also took the phrase less literally, as a metaphor for public humiliation and self-denial.
9:24 whoever wants to save their life will lose it. This paradoxical statement depends on the fact that psych? is used to refer to both physical life and the spiritual self, or “soul.”
9:25 to gain the whole world. The same principle is extended beyond life itself to the values that govern most people’s lifestyle. “Gain” and “forfeit” are commercial metaphors.
9:26 the Son of Man . . . when he comes. The imagery is drawn from Daniel 7:13–14, where the “one like a son of man” comes before God to be enthroned in glory as sovereign and judge of all nations. That judgment is ultimately more important than human opposition, even if it leads to physical martyrdom.
9:27 will not taste death before they see the kingdom of God. In the light of the parallel in Mark 9:1, the reference is probably to Jesus’s triumphant establishment of God’s kingdom on earth, despite his own death. This would become “visible,” before some of them had “tasted death” in martyrdom, as the gospel spread and the church grew after Jesus’s resurrection. But it is also possible, especially since this is said of only “some” of those present, that it refers to the experience of witnessing the transfiguration, which follows immediately.
9:28 went up onto a mountain to pray. The location (traditionally Mount Tabor) is not important; it was a place apart from normal life, as often when Jesus prayed. For the “inner circle” of Peter, John, and James, see on 8:51.
9:29 the appearance of his face changed. In this unique event the “human incognito” of the Son of God is transcended, and his true glory is revealed (note the mention of “glory” in 9:31–32).
9:30 Two men, Moses and Elijah. The reappearance of men from the distant past (both of whom had left this earth in mysterious circumstances [Deut. 34:5–6; 2 Kings 2:11]) adds to the numinous atmosphere. Both were prophets, and both had met God on a mountain. Both were expected in Jewish belief to be part of the eschatological scenario. Their presence confirms Jesus’s status as the Messiah.
9:31 They spoke about his departure. “Departure” (exodos) probably focuses on Jesus’s death, but perhaps it also includes his resurrection as the completion of his triumphant “exodus” progress. Glory and death are thus inextricably linked. Jesus’s death is not an accident; it is the center of his messianic mission, soon to be “brought to fulfillment.”
9:33 He did not know what he was saying. Overwhelmed by the awesome spectacle, Peter blurts out his first thoughts. Such distinguished visitors need suitable shelter on the mountain, and it is a good thing that the disciples are there to provide it. Peter does not realize that this vision is not meant to last.
9:35 This is my Son, whom I have chosen; listen to him. What God declared in the second person to Jesus in 3:22 is now repeated (with “chosen” rather than “beloved”) for the benefit of the disciples. The added instruction “Listen to him,” uttered after the appearance of Moses with Jesus, echoes Moses’s prophecy (which featured in some messianic expectations) of a future prophet like himself to whom “You must listen” (Deut. 18:15); Jesus the Messiah now takes the place of Moses. But the central element in this declaration is again the identification of Jesus as the Son of God.
Theological Insights
This passage is packed with christological significance. Jesus is, as people supposed, a prophet (perhaps the prophet like Moses), but he is also more than a prophet—the Messiah. The appearance of Moses and Elijah with him adds to the sense of eschatological fulfillment. But the supernatural glory of the vision on the mountain and the divine declaration from the cloud take us beyond a merely human messiah to the Son of God, who himself shares in the essential glory of God.
Yet mixed in with this positive Christology is the strong note of suffering and death, not as an unfortunate diversion from the messianic mission but rather as its heart. The Son of Man who will appear in glory (9:26) is the same one who must be rejected by his own people (9:22). So to follow him is to take the road not to popularity and influence but instead to self-denial and the real possibility of martyrdom. And yet beyond his death is his resurrection and, for his disciples, the prospect of sharing his glory in the kingdom of God.
What a rich yet paradoxical theological harvest from a mere nineteen verses!
Teaching the Text
These verses contain at least three sections, each of which could be taught on its own:
the revelation of Jesus as the Messiah, and the paradoxical nature of that messiahship
the teaching of Jesus on discipleship
the revelation of his glory on the mountain
But to isolate any of these from the others is to lose the remarkable overall balance that makes this section as a whole such a satisfying, if surprising, complex of teaching. It is better if the whole section can be taken together.
A lesson or sermon on this material should focus on both its implications for Christology (the identity of Jesus) and for discipleship. Luke’s Gospel reaches a key turning point here as Peter recognizes and confesses that Jesus is the Messiah. Yet Jesus surprisingly defines that messiahship not as physical conquest but as suffering and sacrifice. This theme—the Messiah must suffer—is an important one in Luke-Acts and will reach its climax in the Gospel in the account of the Emmaus disciples after the resurrection (24:25–27). Jesus’s teaching about suffering here applies not only to himself but also to his disciples, who must take up their cross daily and follow him (9:23). The transfiguration that follows both confirms the glorious identity of Jesus as Messiah and also provides assurance for the disciples that after suffering will come vindication and glory.
The prominence of Peter in the final scene invites us to use him (as a typical disciple) as a lead-in to grasping the significance of these events, as we follow the rollercoaster of his perceptions and emotions:
his pride in at last grasping Jesus’s messiahship
his dismay when Jesus not only forbids them to speak of this but also apparently undermines it immediately by talking about rejection and death at the hands of the very people whom the Messiah has come to deliver
his perception of what was meant by being raised on the third day
the sinking feeling when Jesus speaks of the need to take up the cross and not to be ashamed of him
the exhilaration of the mountaintop experience, but also the scary sight of a transformed Jesus and two dead men returned
the embarrassment of his inappropriate words
his possible shift of perceptions about Jesus from 9:20 to 9:36
Illustrating the Text
Sometimes one must lose one’s life in order to gain it.
Literature: Till We Have Faces, by C. S. Lewis. This novel (1956), based on the myth of Cupid and Psyche, is reputed by some sources to be one of Lewis’s own favorite works. In it, the protagonist, Orual, has a lifelong battle with the gods (God).
She tries to meet the longings of her troubled soul through a series of people in her life, claiming to love them, but using them for the sake of her own needs. The gods pursue her relentlessly. Finally, having lost many of those around her and unable any longer to fill the God-shaped vacuum, she begins to submit. She says, “But when the craving went, nearly all that I called myself went with it. It is as if my whole soul had been one tooth and now that tooth was drawn. I was a gap.” And at the end, when Orual is about to die, she writes in the second book of her recorded battle with the gods, “I ended my first book with the words no answer. I know now, Lord, why you utter no answer. You are yourself the answer. Before your face questions die away. What other answer could suffice?”1
Beyond the suffering, there is glory.
Literature/Film: Henry V, by William Shakespeare. In this famous St. Crispin’s Day speech, Henry V inspires his troops during the Battle of Agincourt (1415). It emphasizes (especially in the last few lines) the glory that follows heroic suffering. Kenneth Branagh’s rendition of the speech from the 1989 film version is particularly powerful.
This day is called the feast of Crispian:
He that outlives this day, and comes safe home,
Will stand a tip-toe when the day is named,
And rouse him at the name of Crispian.
He that shall live this day, and see old age,
Will yearly on the vigil feast his neighbours,
And say ‘To-morrow is Saint Crispian:’
Then will he strip his sleeve and show his scars.
And say ‘These wounds I had on Crispin’s day.’
Old men forget: yet all shall be forgot,
But he’ll remember with advantages
What feats he did that day: then shall our names,
Familiar in his mouth as household words
Harry the king, Bedford and Exeter,
Warwick and Talbot, Salisbury and Gloucester,
Be in their flowing cups freshly remember’d.
This story shall the good man teach his son;
And Crispin Crispian shall ne’er go by,
From this day to the ending of the world,
But we in it shall be remember’d;
We few, we happy few, we band of brothers;
For he to-day that sheds his blood with me
Shall be my brother; be he ne’er so vile,
This day shall gentle his condition:
And gentlemen in England now a-bed
Shall think themselves accursed they were not here,
And hold their manhoods cheap whiles any speaks
That fought with us upon Saint Crispin’s day.2
