Acts 1:9-11 – The Ascension of Jesus

The Ascension of Jesus strikes me as an undervalued event in the teaching of the Protestant church. We do a great job on the death and resurrection of Jesus, especially around Easter, but rarely do we reflect much on the Ascension. There is an “Ascension Sunday” in liturgical calendars, but most Protestant churches do not make too much of the Ascension in our post-Easter worship.

The Ascension of Jesus

It is a bit of a surprise to find out that the Ascension is not found in Matthew or John and only appears in the longer ending of Mark. The last few verses of Luke mention the Ascension in anticipation of the longer telling of the story in Acts 1. The Ascension functions in the story of Luke-Acts the climax of everything Jesus taught about himself and his role as messiah, but also as an anticipation of the direction of the narrative plot of Acts, but also the theology of Acts.

With respect to the narrative development of the book, the message that Jesus is the Messiah will be preached in the next chapter, starting in Jerusalem, but ultimately the message will go to “the ends of the world.” Acts 28 concludes the book with Paul in a synagogue in Rome, still giving witness to the fact that Jesus was the Messiah.

With respect to theology, the Ascension is critically important for Luke’s Christology. As Keener points out, this event is anticipated as early as Luke 9:51 (an allusion to his being “taken up.” This is a rare word (ἀνάλημψις), only used here in the New Testament or the LXX, but it is used for a similar even in the Assumption of Moses and in Testament of Levi 18.3 to describe the rising of a “new priest” who will judge the Earth. This person is “like a star” and he will shall take away all darkness from under heaven, and there shall be peace in all the earth.”

The Ascension is also important for Luke’s view of the future. The departure of Jesus anticipates the way he will return, as the angelic messages state in Acts 1:11. I think that the pattern Luke has in mind here is drawn from Ezekiel 10 and 11. There the prophet sees the Glory of God depart from the temple to the east, stopping on a mountain to the east of the Temple before ascending to heaven (11:22-23). After the Glory of God has departed, Ezekiel is told that there will be no more delay, the city will fall and the long exile will begin.

By describing the Ascension as he does in Acts 1, Luke is calling attention to the fact that Jesus is the Glory of God and that his departure signals the continuation of the long exile of Israel. But like Ezekiel, there is a promise that the Glory of God will return to Israel again and he will “restore the kingdom.”

What are some other ways the Ascension functions as a part of  Luke’s theology of Jesus? Looking ahead in Acts, what else does this important event anticipate?

Acts 1:6 – “Will You Now Restore the Kingdom to Israel?”

In Acts 1:6, some disciples wonder if Jesus was now going to “restore the kingdom to Israel.” This question is reminiscent of the Olivet Discourse in Luke 21:5-37, where the disciples ask about the coming judgment on the Temple. When they asked “when will this happen” in Luke 21, Jesus’ answer implied that it would happen very soon, within a generation (Luke 21:32).

What prompts the question is Jesus’ command to remain in Jerusalem until they are baptized with the Holy Spirit “not many days from now.” As Keener observes, talk of the Spirit’s outpouring was de facto eschatological in character” (Acts, 1:682). Many texts from the Hebrew Bible indicate that the eschatological age would be characterized by the Spirit of God on all his people (Joel 2:28-31, which Peter quotes in the next chapter, but also Isa 42:1, 44:3, 59:21). If the Spirit is coming, then the time of the restoration of the Kingdom to Israel must be soon.

Return of the KingAfter the resurrection of Jesus, it was only natural for the disciples to think that Jesus would now enter the Temple in the power and glory of his resurrection and begin to reform the religion of Israel and begin the process of evangelizing the nations. This was a clear expectation of the Messiah’s activity. Beginning with the people of God, Messiah would either convert the enemies of Israel or destroy them. On a historical level, the question the disciples ask resonates with many other Jews living in the mid 30’s A.D.

The verb translated “restore” here (ἀποκαθίστημι) is a key eschatological term. It appears in Malachi 4:6 (LXX 3:23) and LXX Daniel 4:26, and it anticipates Acts 3:21 where the word appears in an eschatological context. The hope of Israel was that the kingdom would be restored to them as the prophets had predicted (Isa 2:2, 49:6; Jer 16:15; 31:27-34).

Isaiah 2:2-4 In the last days the mountain of the Lord’s temple will be established as chief among the mountains; it will be raised above the hills, and all nations will stream to it. 3Many peoples will come and say, “Come, let us go up to the mountain of the Lord, to the house of the God of Jacob. He will teach us his ways, so that we may walk in his paths.” The law will go out from Zion, the word of the Lord from Jerusalem. 4He will judge between the nations and will settle disputes for many peoples. They will beat their swords into plowshares and their spears into pruning hooks. Nation will not take up sword against nation, nor will they train for war anymore.

In fact, Luke began his first book with the hope of the coming Messiah in the Song of Zechariah (Luke 1:69-74) as well as the words of Simeon in the Temple (Luke 2:24-32).

The disciples expect Jesus to tell them that he is in fact about to restore the Kingdom and take his father David’s throne in Jerusalem. Much like the crowds in Luke 19:11, the disciples expect the Kingdom of God, as described by the prophets, to arrive at that moment.

Yet it is no surprise when Jesus reminds them it is not for them to known when the kingdom will be restored. The idea of an interim period between the present and the coming kingdom is well known in Second Temple Period Judaism. For example in 4 Ezra 4:33-37 the prophet asks “How long and when will these things be? Why are our years few and evil?” The answer in this late first century text is that “the time of threshing is delayed for the righteous—on account of the sins of those who dwell on earth.” The interim is to be used wisely. The new age will certainly dawn, but in the meantime the righteous will continue to labor. Many of Jesus’ parables have a similar theme (the Ten Virgins in Matt 25:1-14, for example).

As for the disciples, they are called to be witnesses to the good news of Jesus in Jerusalem, Judea, Samaria, and all the earth. To some extent, the kingdom is about to begin in the Temple in a manner which is not unlike what many expected. That the kingdom would be given to a group of Galileans rather than a faction within Judaism (Pharisees, Essenes, etc.) was not expected at all. These men are quite literally the most unlikely group of people to be commissioned with the task of announcing the Messiah to Israel and then the rest of the world!

Acts 1:8 – “You Will Be My Witnesses”

When asked if he was about to restore the Kingdom to Israel, Jesus reminds his disciples that “it is not for them to know” when the kingdom will be restored. Rather than knowing the “times and dates” God has planned, the disciples are to be witnesses to the good news of Jesus in Jerusalem, Judea, Samaria, and all the earth. To some extent, the kingdom is about to begin in the Temple in a manner which is not unlike what many expected. The Holy Spirit will fall upon people and they will speak the Word of God in power in the Temple itself.

Acts 1_8

These men are to be witnesses, a very important word in Luke-Acts and this command is in many ways programmatic for the chapters which follow. In the chapters which follow, the 12 disciples are called witnesses 8 times, and the Holy Spirit bears witness on their behalf (Acts 5:32). Both Paul (22:15, and 26:16) and Stephen (22:20) are called witnesses in Acts.

The disciples are to give testimony of who Jesus was (the messiah) and what Jesus did (died for the forgiveness of sins) and what he intends to do (return to establish his kingdom). They are all eyewitnesses of the life of Jesus, his death and resurrection, and they will be witnesses to the coming of the Holy Spirit (in Acts 2). They are Jesus’ own personal representatives sent to report to others what Jesus said and did.

As in the modern use of the word, a ‘witness” often functioned in a legal context, giving testimony in a court case. As the disciples give their testimony in various speeches, sermons or other teaching opportunities, they are offering evidence concerning who Jesus is. This evidence can be corroborated other eye-witnesses. In Luke 1:2, the author claims to have done this already, confirming the events of his Gospel by eyewitnesses. That Luke himself is a part of the story after Acts 16 indicates that he is an eyewitness himself and can confirm the truth of his document.

This is an important historical point, since what accounts for evidence for a first century historian differs from that of a modern writer. As Keener points out, to call upon witnesses is common in other Greco-Roman histories. An eyewitness was the most important evidence a writer could give. Polybius, for example claimed that “sight is, according to Heracleitus, by far the truer; for eyes are surer witnesses than ears” (Hist. 12.27). As I suggested in a previous post, Luke can be both historical and theological, since the two are virtually the same in the literary world of the first century.

This commission to be the witnesses of the Messiah in Jerusalem is based on the activity of the Holy Spirit. They are verbally commissioned, but it will be the reception of the Holy Spirit which empowers them to preach and confirms the words of their preaching (through signs and miracles).

How does this theme of “witness” work out in the Book of Acts? How are the disciples witnesses for the Messiah? To what extent is “eye-witness” important in modern evangelism? (Or, is it?)

Acts 1:1-3 – Jesus Gave Many Convincing Proofs

After the resurrection, Jesus gives many “convincing proofs” of the resurrection (1:3). The word Luke selects for “proof” (τεκμήριον) in this opening paragraph is word associated with other historical texts in the ancient world. The word is different than witness (a key word in Luke’s introduction to Acts) since “proof” refers to “evidential proof credible on its own merits” (EDNT, 340). Keener says the phrase “many proofs” appears in Hellenistic  historiography (1:666). The Greek historian Thucydides, for example, makes a statement the offers proof for the assertion using this word (2.39), and he used the verb in his introduction of his history with the sense of “prove positively” (1.3). I am not sure Luke would have intended this word to be understood in the same sense as Aristotle, who used the word in contrast to fallible signs (σημεῖον). For Aristotle, the word refers to “demonstrative proof” (LSJ).

Road to Emmaus Robert_Zund_ZUR010

Another way of understanding of the word is as a “confirming sign.” When Josephus created a speech for Joshua just before the Israelites enter the Promised Land, he described the miracles Israel experienced in the wilderness as “many signs” (Ant. 5.39 διὰ πολλῶν τεκμηρίων). This is intriguing; perhaps Luke refers to Jesus doing things to prove he was actually alive (eating with the disciples, Luke 24:41-43) or miracles (John 21:4-8). The “signs” were proof Jesus was indeed alive.

Most likely the “evidence” Jesus gave was scriptural proof drawn from the Hebrew Bible. Jesus explained to the disciples the key texts about the messiah and demonstrated to them Scripture anticipated a suffering messiah who would die and rise again. Certainly the disciples needed to be convinced Jesus had really died and was not alive (John 20, Thomas), the bulk of the proof took the form of opening the disciples minds to the idea that messiah came to suffer and die before judging and ruling the nations. This is exactly how Luke ended his gospel, the disciples who met Jesus on the road to Emmaus: “and beginning with Moses and all the Prophets, he interpreted to them in all the Scriptures the things concerning himself” (Luke 24:27).

Why would Jesus need to provide “convincing proofs”? In Second Temple Period Judaism, no one expected the messiah would die, let alone rise from the dead. A possible exception is 4 Ezra, but even in this book the messiah establishes a kingdom and dies after a very long reign. There was no Jewish expectation the suffering servant of Isaiah 40-55 would die, and no one read that text as messianic quite the way Christians do.

Jesus gives these proofs or signs to draw his disciples to the conclusion the messiah had to die and be raised from the dead. This claim demands a decision from disciples but also the reader of Acts. If Jesus was who he claimed, then what is going to happen at Pentecost?

When we read Peter’s sermons in Acts 2-3, there are several passages from the Hebrew Bible which could qualify as “convincing proofs.” What does Peter claim about Jesus in these sermons?

Acts and Mission Strategy

Following Ekhard Scnabel (Paul the Missionary), there are three elements which are a part of this missionary work. First, the missionary communicates the good news of Jesus as the Messiah and Savior. Second, the missionary communicates a new way of life to those who respond to the good news. This necessarily means that social and cultural patterns must change in the light of the Gospel. Third, the missionary tries to integrate these new believers into a new community. The new believers are a new family (brothers and sisters) or a new community (a citizenship in heaven).

Paul, flashing his Missionary Card

Paul, flashing his Missionary Card

By in large, I agree with this general outline of method. It is not difficult to demonstrate that Paul’s message centered on Jesus as the Messiah and that his death provided some kid of solution to the problem of sin. What is more, Paul is clear in his letters that when one is “in Christ” everything has changed. The believer is a new creation and therefore has a new relationship with God. The believer has a new family, which means there are new family obligations which bear on social connections. The new believer’s relationship with God has social and ethical ramifications which go beyond the typical confines of “religion” in the ancient world.

These elements of mission also explain many of the problems Paul faces in fulfilling his calling. How does a person “live out” this new relationship with Christ? How do Gentiles relate to the God of the Hebrew Bible? If Gentiles are in Christ, how ought the relate to the pagan world? Two examples come to mind. On the one hand, should the Gentile believer in Christ accept the Jewish law as normative for their worship and practice?

On the other hand, can someone who is “in Christ” attend a birthday celebration at a pagan temple without actually worshiping any god? In the first case, the Gentile is radically changing his pattern of life which would create a social break with his culture. In the second case, he is making a minor adjustment in order to remain socially accepted. These are not straw-men, since there are clear cases of both things happening in the New Testament. I assume Paul would be someplace between these two extremes, based on a reading of Galatians and 1 Corinthians.

I point this out because it highlights the difficulty of applying Acts as a one-size-fits-all mission strategy. I think that Schnabel’s first point clearly describes the activity of the Jewish church in Jerusalem, but does the second? To what extent does Peter have to instruct Jewish believers in proper practice? The third point may have applied although quite different in practice from the later Pauline congregations.

What is remarkable to me is that this last problem is a non-factor for the first nine chapters of Acts. Peter and the twelve do not face the problem of what to do with Gentiles since they do not target them at all. Even after Peter is sent to Cornelius, there is no really problem since the God-fearing Gentiles are nearly Jews by way of practice!
