Session 2.6: November 3, 2023
Scripture Reading: Acts 1:12 - 2:13
12 Then they returned to Jerusalem from the mountain called the Mount of Olives (which is near Jerusalem, a Sabbath day’s journey away). 13 When they had entered Jerusalem, they went to the upstairs room where they were staying. Peter and John, and James, and Andrew, Philip and Thomas, Bartholomew and Matthew, James son of Alphaeus and Simon the Zealot, and Judas son of James were there. 14 All these continued together in prayer with one mind, together with the women, along with Mary the mother of Jesus, and his brothers. 15 In those days Peter stood up among the believers (a gathering of about 120 people) and said, 16 “Brothers, the scripture had to be fulfilled that the Holy Spirit foretold through David concerning Judas—who became the guide for those who arrested Jesus— 17 for he was counted as one of us and received a share in this ministry.” 18 (Now this man Judas acquired a field with the reward of his unjust deed, and falling headfirst he burst open in the middle and all his intestines gushed out. 19 This became known to all who lived in Jerusalem, so that in their own language they called that field Hakeldama, that is, “Field of Blood.”) 20 “For it is written in the book of Psalms, ‘Let his house become deserted, and let there be no one to live in it,’ and ‘Let another take his position of responsibility.’ 21 Thus one of the men who have accompanied us during all the time the Lord Jesus associated with us, 22 beginning from his baptism by John until the day he was taken up from us—one of these must become a witness of his resurrection together with us.” 23 So they proposed two candidates: Joseph called Barsabbas (also called Justus) and Matthias. 24 Then they prayed, “Lord, you know the hearts of all. Show us which one of these two you have chosen 25 to assume the task of this service and apostleship from which Judas turned aside to go to his own place.” 26 Then they cast lots for them, and the one chosen was Matthias; so he was counted with the eleven apostles.
1 Now when the day of Pentecost had come, they were all together in one place. 2 Suddenly a sound like a violent wind blowing came from heaven and filled the entire house where they were sitting. 3 And tongues spreading out like a fire appeared to them and came to rest on each one of them. 4 All of them were filled with the Holy Spirit, and they began to speak in other languages as the Spirit enabled them.
5 Now there were devout Jews from every nation under heaven residing in Jerusalem. 6 When this sound occurred, a crowd gathered and was in confusion because each one heard them speaking in his own language. 7 Completely baffled, they said, “Aren’t all these who are speaking Galileans? 8 And how is it that each one of us hears them in our own native language? 9 Parthians, Medes, Elamites, and residents of Mesopotamia, Judea and Cappadocia, Pontus and the province of Asia, 10 Phrygia and Pamphylia, Egypt and the parts of Libya near Cyrene, and visitors from Rome, 11 both Jews and proselytes, Cretans and Arabs—we hear them speaking in our own languages about the great deeds God has done!” 12 All were astounded and greatly confused, saying to one another, “What does this mean?” 13 But others jeered at the speakers, saying, “They are drunk on new wine!”
Main Themes
WAITING ON THE PROMISE AND SELECTING A NEW APOSTLE
The fulfillment of Acts 1: 8 is interrupted by a problem left over from the gospel. One of the twelve witnesses must be replaced. Yet there is also a sense in which 1:12-26 is not simply a “problem” but part of the preparation for Pentecost. The disciples pray together (which is often linked with the Spirit’s descent) and the leadership structure for the righteous remnant of Israel is restored.
The Physical Setting—The Upper Room
One might suppose that the entire group was staying in one upper room, but surely Luke means only that they habitually met there. No upper room would accommodate 120 people, and certainly the women would not have stayed with the men. One may also ask: which upper room? The definite article might suggest that this was a well-known upper room. The reader of Luke-Acts will infer that it is probably the same upper room that hosted the Last Supper (Luke 22:11-12).
The Theological Setting—The Remnant
What do I mean by a righteous remnant? Throughout the rocky history of the nation of Israel, full of disobedience to God, a small contingent always remained faithful. This was the remnant—quite literally, what remained and rebuilt after each of God’s judgments. One can hardly avoid connecting this idea of a righteous remnant to the apostles, particularly given their number (12, just like the tribes of Israel). Thus, selecting a twelfth apostle was important to restore the symbolic value of the first leaders of the church. Israel’s remnant fits well into the context of the Spirit and Israel’s restoration and role in salvation. In fact, this is the fulfillment of God’s first covenant with his people. All the way back in Genesis, God promised Abraham:
Now the Lord said to Abram,
“Go out from your country, your relatives, and your father’s household
to the land that I will show you.
Then I will make you into a great nation, and I will bless you,
and I will make your name great,
so that you will exemplify divine blessing.
I will bless those who bless you,
but the one who treats you lightly I must curse,
so that all the families of the earth may receive blessing through you.” Genesis 12:1-3
The continuity between Genesis and Acts is incredible.
12 out of (Approximately) 120 and the Language of Calling
The connection between the apostles and the remnant is reinforced when we notice the number of apostles and how Peter spoke of their calling. Peter notes that Judas the traitor had received the same privileges of calling that the other eleven had. Judas is described as being “numbered.” Peter describes the apostolic calling here as a “service” in which Judas once shared. Peter also describes this calling in terms of a “portion” or “lot” in the service. This description reinforces the fact that possessors of the office of apostle were chosen by divine purpose, including the betrayer. There is a beautiful connection between Peter’s language and the Old Testament. In Numbers, for example, God chooses the Levites to serve as his priests:
5 The Lord spoke to Moses: 6 “Bring the tribe of Levi near, and present them before Aaron the priest, that they may serve him. 7 They are responsible for his needs and the needs of the whole community before the tent of meeting, by attending to the service of the tabernacle. 8 And they are responsible for all the furnishings of the tent of meeting, and for the needs of the Israelites, as they serve in the tabernacle. 9 You are to assign the Levites to Aaron and his sons; they will be assigned exclusively to him out of all the Israelites. 10 So you are to appoint Aaron and his sons, and they will be responsible for their priesthood, but the unauthorized person who comes near must be put to death.”
11 Then the Lord spoke to Moses: 12 “Look, I myself have taken the Levites from among the Israelites instead of every firstborn who opens the womb among the Israelites. So the Levites belong to me, 13 because all the firstborn are mine. When I destroyed all the firstborn in the land of Egypt, I set apart for myself all the firstborn in Israel, both man and beast. They belong to me. I am the Lord.” Number 3:5-13
Furthermore, notice the numbers involved. Twelve are chosen out of approximately 120. A tenth. Like the tithe.
Any tithe of the land, from the grain of the land or from the fruit of the trees, belongs to the Lord; it is holy to the Lord. Leviticus 27:30
Or exactly like in Nehemiah (during the restoration of Israel after the Babylonian exile).
So the leaders of the people settled in Jerusalem, while the rest of the people cast lots to bring one out of every ten to settle in Jerusalem, the holy city, while the other nine remained in other cities. The people gave their blessing on all the men who volunteered to settle in Jerusalem. Nehemiah 11:1-2
Sometimes I think we miss the point that Acts is the restoration of Israel through the remnant of the people of God. Put simply, the Spirit comes, the sick are healed, the remnant rebuilds. Acts is the coming of the kingdom.
CHOOSING A SUCCESSOR
Many church assemblies in Acts addressed controversial issues (Acts 6:1; 11:2-3; 15:1-7; 21:21-22); the matter of choosing Judas’s successor, however, seems not so much controversial as necessary to prepare a united witness for the time when the Spirit would come.
The Problem—Judas the Betrayer
In Acts, Peter speaks of Judas as a guide to those who arrested Jesus. However, Luke’s audience would surely think of the fuller account of this betrayal in Luke. Treachery or betrayal was considered one of the most heinous offenses in antiquity, a breach of sacred trust. Notice that just like in the Gospel John, this treachery is not treated as a surprise. Instead, it was foretold. Jesus knew what would happen if he remained with Judas. Jesus went intentionally to his grave.
How Did Judas Die?
In the Bible, we have multiple accounts of Judas’s death. Yet Matthew’s version of Judas’s demise seems to differ at key points from Luke’s. Is it possible to reconcile these accounts?
Now when Judas, who had betrayed him, saw that Jesus had been condemned, he regretted what he had done and returned the 30 silver coins to the chief priests and the elders, saying, “I have sinned by betraying innocent blood!” But they said, “What is that to us? You take care of it yourself!” So Judas threw the silver coins into the temple and left. Then he went out and hanged himself. The chief priests took the silver and said, “It is not lawful to put this into the temple treasury, since it is blood money.” After consulting together they bought the Potter’s Field with it, as a burial place for foreigners. For this reason that field has been called the “Field of Blood” to this day. Then what was spoken by Jeremiah the prophet was fulfilled: “They took the 30 silver coins, the price of the one whose price had been set by the people of Israel, and they gave them for the potter’s field, as the Lord commanded me.” Matthew 27:3-10
The major differences are (1) whether Judas obtained the field himself (Acts 1:18 vs. Matt 27:7) and (2) how he met his end (Acts 1:18 vs. Matt 27:5). Regarding the first problem, perhaps Luke’s narrative stems from his (or his sources’) abbreviation of a longer account that could have included the high priests or that the priests, counting the money as legally belonging to Judas, could have bought the field in Judas’s name. Regarding the second problem, plausibly, if Judas hanged himself from a tall tree or building in the sort of rocky field natural in Judean hill country, his innards might well spatter (assuming that the tree was tall) when someone cut or (less likely) untied the rope (or it eventually broke). (This assumes that the body was cut down before it decomposed or before it was picked apart by scavengers; in view of Judean piety, this assumption is likely, again assuming that the corpse was found, as it probably would have been if near Jerusalem.) Others have suggested the possibility of the body’s being torn down and opened by wild dogs, fitting both versions. Luke or his source would then report the gorier fate of Judas’s corpse rather than his actual mode of death.
Qualifications for Apostleship
Peter lists the qualifications (1:20) for Judas’s replacement. This gives us great insight into the requirements to be an apostle, so we should spend a minute or two making note of them.
Antiquity was no stranger to lists of qualifications, particularly for reliable witnesses. Peter could have safely assumed that Judas’ replacement had to be of good moral character and male. (Male testimony was nearly always accepted most highly. There could also be theological reasons to select a male.) But, what were the special qualifications to be not simply a witness but an apostle?
Thus one of the men who have accompanied us during all the time the Lord Jesus associated with us, beginning from his baptism by John until the day he was taken up from us—one of these must become a witness of his resurrection together with us. Acts 1:21-22
This looks like one requirement but, in a sense, it is two. First, an apostle had to be a firsthand eyewitness of all of Jesus’ ministry—from his baptism to his resurrection. Choosing those who had spent the most time with Jesus was important so that they could guarantee and interpret the message about him. Moreover, in antiquity just like now, eyewitness sources were considered the best, and those further removed from the witnesses were considered weaker.
Second, and this is implied but it is no less important, an apostle had to be one of those who persevered. At the cross, all disciples deserted Jesus. So that desertion could be ignored (or all persons would be disqualified from discipleship). Nevertheless, throughout Jesus’ ministry many of his followers left him. Recall, for example, the crowd’s reaction after Jesus fed the five thousand and taught them that he was the bread of life:
I am the bread of life. 49 Your ancestors ate the manna in the wilderness, and they died. This is the bread that has come down from heaven, so that a person may eat from it and not die. 51 I am the living bread that came down from heaven. If anyone eats from this bread he will live forever. The bread that I will give for the life of the world is my flesh.”
Then the Jews who were hostile to Jesus began to argue with one another, “How can this man give us his flesh to eat?” Jesus said to them, “I tell you the solemn truth, unless you eat the flesh of the Son of Man and drink his blood, you have no life in yourselves.
…
Then many of his disciples, when they heard these things, said, “This is a difficult saying! Who can understand it?” When Jesus was aware that his disciples were complaining about this, he said to them, “Does this cause you to be offended? Then what if you see the Son of Man ascending where he was before? The Spirit is the one who gives life; human nature is of no help! The words that I have spoken to you are spirit and are life. But there are some of you who do not believe.” (For Jesus had already known from the beginning who those were who did not believe, and who it was who would betray him.)
…
After this many of his disciples quit following him and did not accompany him any longer. So Jesus said to the twelve, “You don’t want to go away too, do you?” John 6:41b-53, 60-64, 66-67
Two Are Proposed, Lots Are Cast
Two candidates are proposed by the community: Joseph called Barsabbas (also called Justus) and Matthias. (“Joseph” was a very common name, hence requiring some further description. Historians often provided additional names for historical figures with common names.)
How did the apostles choose between the two men? First, they prayed in recognition of two facts: (1) God knows the hearts of all men, and (2) God selects the apostles.
Then they prayed, “Lord, you know the hearts of all. Show us which one of these two you have chosen 25 to assume the task of this service and apostleship from which Judas turned aside to go to his own place.” Acts 1:24-25
I discussed God’s election of his apostles above. The idea that God knows men’s hearts is also not new. We read statements to that effect in John, and it appears throughout the Old Testament. For example:
But the Lord said to Samuel, “Don’t be impressed by his appearance or his height, for I have rejected him. God does not view things the way people do. People look on the outward appearance, but the Lord looks at the heart.” 1 Samuel 16:7
So, the assembly’s prayer indicates that they are depending on God to provide the right replacement for Judas. The Lord’s “choosing” Matthias provides continuity with his “choosing” other apostles. The question we often have is whether casting lots was the proper way to let God choose or communicate his decision.
(By the way, what are lots? The lots may have been stones or pottery fragments shaken in a container, with Matthias’s being the first to emerge.)
Lot oracles (usually answering yes/no questions or other binary choices) were common in antiquity. Many cities had dice oracles for their citizens to consult in city centers. More relevant here is the use of lots for choosing public officials. Various classical Athenian officials were chosen by lot. Democracies in particular, but also other Greek cities, used lots to distribute, with a minimum of conflict, public offices among those who were equally eligible. The use of lots is also well documented in Ptolemaic and Roman Egypt. In the Roman Republic, Romans could evade partisan politics by drawing lots. Romans did not use lots for selecting normal magistrates but did use them for selecting judges and other offices. Lots could be used to decide who would lead in battle, which general would go to war, which positions the legions would take in battle, which members of a disgraced cohort would be beaten to death, who might be sacrificed, and whose property would have to be sold.
The point is that the apostles did not use some weird or irresponsible system to decide between Joseph and Matthias. They used a fairly standard procedure to elect officials when the candidates were equally qualified. Perhaps this is why casting lots seemed unobjectionable to the apostles and the rest of the believers. At the same time, we should notice that casting lots is not used again by the apostles. So, we should not consider its use prescriptive for the church.
Pentecost
All Together in One Place—Where?
The Pentecost miracle happened when all the disciples were together in one place (Acts 2:1). To be honest, I always assumed that was the upper room mentioned in chapter 1. Maybe that’s right, but maybe it isn’t. If one inspects the text closely, the place is not specified. There are two choices for this unspecified location: the temple or a private home (presumably the one with the upper room).
Before we consider the evidence, why would think the temple was their gathering place? The narrative that follows verse 2:1 implies that either they were in or at some point they enter the temple courts. Nowhere else in Jerusalem could they have drawn a crowd sufficient to produce three thousand converts, whereas the Temple Mount could fit about seventy-five thousand people. So, the disciples were either in or near the temple. Let’s consider some of the evidence.
The apostles frequently met in the temple (Luke 24:53; Acts 2:46; 5:12) but also “from house to house” (Acts 2:46), so both options are plausible. But maybe we can figure it out from verse two, which refers to the “entire house” being filled. Is the term “house" dispositive of the issue? Not decisively. The temple or tabernacle is called a house in Luke 6:4 and 19:46 (quoting Isaiah 56) and Acts 7:46-47; but the term also appears in contrast to the temple (Luke 1:23; Acts 2:46; 5:42), and Luke’s emphasis on house meetings makes that sense more likely (Acts 2:46; 5:42; 20:20).
If we favor preceding context over following context (i.e., chapter 1 over chapter 3), as someone reading the book in sequence for the first time would do and consider the allusion to the disciples’ unity, we might be pointed back to the upper room of 1:13. If this is the case, we might conclude that the disciples rushed from there into the temple, still praising God. A transition from upper room to temple is plausible. Any home large enough to host huge numbers in an upper room would have to have been in the Upper City near the Temple Mount.
When? During the Festival of Pentecost
Pentecost, another name for the Feast of Weeks, was one of the great Jewish pilgrimage festivals, and as such, it would have been heavily attended by Jews from all over the world (as they knew it) and perhaps some Gentile tourists. Its history dates to the Old Testament. As a scholar explains:
The Passover feast was celebrated at twilight in the evening of the fourteenth day of the first month (Lev 23:5). It was followed on the fifteenth day by the beginning of the closely related seven-day Feast of Unleavened Bread (Lev 23:6). On the next day, the sixteenth, the first fruits of the (barley) harvest had to be brought to the Lord (Lev 23:11, cf. vv. 6-7). Seven weeks and one day later, the Feast of Weeks (Pentecost) was celebrated, during which, among other things, offerings from the grain (wheat) harvest and two loaves of bread had to be brought to God (Exod 34:22; Lev 23:1517). (The fact that this festival was on the fiftieth day later gave rise to the name Pentecost, from the Greek word for “fiftieth.”)
Although many ancient estimates of festival attendance may be exaggerations (e.g., later rabbinic estimates), massive attendance (in the thousands or tens of thousands) is not disputed. Such well-attended festivals were not unusual in the Mediterranean. Both pious believers and tourists would attend. Well-to-do Greeks and Romans apparently visited sanctuaries as tourists, and it is reasonable to guess that the Jerusalem temple’s grandeur may have drawn a few Gentile tourists. Nevertheless, pilgrims would constitute the vast majority of visitors for Pentecost.
Although Scripture demanded the attendance of all Israelite males at these festivals (Exodus 23:17; 34:23; Deuteronomy 16:16), first-century Jews seem to have applied the requirement only within the Holy Land itself due to practical realities. Some sources suggest that more Diaspora Jews attended Pentecost than Passover because of the difficulties of traveling earlier in the season.
Although Pentecost was originally a harvest festival, eventually a tradition developed that associated the occassion with the giving of Law at Sinai. Whether this tradition was known by Luke and his audience or relevant to them is disputed. Luke certainly does not acknowledge the connection. Luke mentions Pentecost for two clear reasons: he shows that, as Jesus had promised, the disciples did not have long to wait for the gift of the Spirit (1:5), and he explains why so many Diaspora Jews were present to recognize the languages spoken (2:5-12).
The Miracle
Wind and Fire
On Pentecost, God provided objective, external phenomena to confirm the internal empowerment taking place when he filled the church with the Spirit. Yet, we should notice that Luke is reserved in his description. He speaks of it “like” wind and “like” fire, just as he spoke of the Spirit coming on Jesus as “like” a dove. This might be intentional on his part, to prevent the reader from understanding the Spirit as a substance—as the Greeks would have done. Instead, Luke presents a more Jewish and biblical theology, in which the Spirit is only compared to substances.
Why wind and fire? Broadly speaking, this imagery would have connected with anyone in the ancient world. Theophanic storm images of wind and fire were common signs of divine presence. But, is there a more specific connection we should make?
Wind
Wind often indicates the powerful presence of God in the Old Testament. In particular, the scene in Acts evokes Ezekiel 37 (more on that in a minute).
In Acts 2:2, Luke uses a rare term for “wind.” The term πνοῆς appears elsewhere in the New Testament only at Acts 17:25, where it refers to human “breath” as a gift of God (and alludes directly to Gen 2:7). It appears 24 times in the Septuagint, referring especially to the breath of life. Whereas the more common term for “wind” and “breath” in Greek provides more obvious associations with God’s “Spirit,” the term used by Luke points us to Genesis and life-giving. Moreover, Jewish tradition connected the divine breath of Gen 2:7 with the eschatological wind of the Spirit in Ezekiel 37. Jewish people expected an eschatological “wind” of the Spirit to bring the breath of life into the slain of Israel. A redacted version of Ezekiel 37 is presented below:
The hand of the Lord was on me, and he brought me out by the Spirit of the Lord and placed me in the midst of the valley, and it was full of bones. 2 He made me walk all around among them. I realized there were a great many bones in the valley, and they were very dry. 3 He said to me, “Son of man, can these bones live?” I said to him, “Sovereign Lord, you know.” 4 Then he said to me, “Prophesy over these bones, and tell them: ‘Dry bones, listen to the Lord’s message. 5 This is what the Sovereign Lord says to these bones: Look, I am about to infuse breath into you and you will live. 6 I will put tendons on you and muscles over you and will cover you with skin; I will put breath in you, and you will live. Then you will know that I am the Lord.’”
7 So I prophesied as I was commanded. There was a sound when I prophesied— I heard a rattling, and the bones came together, bone to bone. 8 As I watched, I saw tendons on them, then muscles appeared, and skin covered over them from above, but there was no breath in them.
9 He said to me, “Prophesy to the breath—prophesy, son of man—and say to the breath: ‘This is what the Sovereign Lord says: Come from the four winds, O breath, and breathe on these corpses so that they may live.’” 10 So I prophesied as I was commanded, and the breath came into them; they lived and stood on their feet, an extremely great army.
11 Then he said to me, “Son of man, these bones are all the house of Israel. Look, they are saying, ‘Our bones are dry, our hope has perished; we are cut off.’ 12 Therefore prophesy, and tell them, ‘This is what the Sovereign Lord says: Look, I am about to open your graves and will raise you from your graves, my people. I will bring you to the land of Israel. 13 Then you will know that I am the Lord, when I open your graves and raise you from your graves, my people. 14 I will place my breath in you and you will live; I will give you rest in your own land. Then you will know that I am the Lord—I have spoken and I will act, declares the Lord.’”
…
24 “‘My servant David will be king over them; there will be one shepherd for all of them. They will follow my regulations and carefully observe my statutes. 25 They will live in the land I gave to my servant Jacob, in which your fathers lived; they will live in it—they and their children and their grandchildren forever. David my servant will be prince over them forever. 26 I will make a covenant of peace with them; it will be a perpetual covenant with them. I will establish them, increase their numbers, and place my sanctuary among them forever. 27 My dwelling place will be with them; I will be their God, and they will be my people. 28 Then, when my sanctuary is among them forever, the nations will know that I, the Lord, sanctify Israel.’” Ezekiel 37
If you remember from our study of John, Jesus continually promised life, abundant and eternal. We need to look no further than the famous verse, John 3:16
For this is the way God loved the world: He gave his one and only Son, so that everyone who believes in him will not perish but have eternal life.
Notice, therefore, that if the Spirit gives life, and we receive the Spirit now, then Acts is presenting a realized eschatology. Eternal life begins now.
Fire
Fire was also commonly associated with the presence of God in the Old Testament. Perhaps the best-known example is the burning bush:
Now Moses was shepherding the flock of his father-in-law Jethro, the priest of Midian, and he led the flock to the far side of the desert and came to the mountain of God, to Horeb. The angel of the Lord appeared to him in a flame of fire from within a bush. He looked, and the bush was ablaze with fire, but it was not being consumed! Exodus 3:1-3
The other major example (although many more could be provided) is the pillar of fire that guided the Israelites through the desert.
They journeyed from Sukkoth and camped in Etham, on the edge of the desert. Now the Lord was going before them by day in a pillar of cloud to lead them in the way, and by night in a pillar of fire to give them light, so that they could travel day or night. He did not remove the pillar of cloud by day nor the pillar of fire by night from before the people. Exodus 13:20-22
Fire was also an image associated with judgments, including end-time judgments, and purification. More importantly, Luke’s informed audience would quickly connect the fire with Luke 3:16-17 (which, incidentally, contains both motifs).
John answered them all, “I baptize you with water, but one more powerful than I am is coming—I am not worthy to untie the strap of his sandals. He will baptize you with the Holy Spirit and fire. 17 His winnowing fork is in his hand to clean out his threshing floor and to gather the wheat into his storehouse, but the chaff he will burn up with inextinguishable fire.” Luke 3:16-17
Though less common than simply “flames,” the expression “tongues of fire” is common in Jewish texts, perhaps because fire is often said to devour (sometimes translated as consumes). For example, the expression appears in the Qumran scrolls. Of course, Luke may have also selected that comparison to make a connection with the Spirit empowering the disciples to speak in tongues.
Empowered
In Scripture, the phrase “filled with the Spirit” applied to the Spirit’s gifting for skills, whether in sacred craftsmanship (Exodus 31:3; 35:31), for leadership (Deuteronomy 34:9), or for prophecy (Micah 3:8). Luke employs the biblical phrase “filled with the Spirit” frequently, especially for an experience enabling prophets and prophetic inspiration (Luke 1:15, 41, 67) and for power for Christian proclamation, both for apostles (Acts 4: 8; 9:17; 13:9) and others (4:31; 13:52).
Speaking in Tongues
In Greek, the term for tongues, as in tongues of fire or speaking in tongues, is glōssais. Just like in English, the term can refer to a physical, literal tongue (e.g., “I burned my tongue”) or a language. The activity of speaking in tongues is glossolalia, which just means speaking (although it was often used to refer to prophetic speech).
The idea of the Spirit of God enabling Christ followers to speak in tongues is rather novel. There is scant precedent. In one document from Qumran, different angels apparently lead the heavenly worship on successive Sabbaths in different languages. There is also a Jewish source speaking of divine sashes that allowed some women to speak in Angelic languages—but this source may be later than Acts (and the languages spoken by the women are described as intelligible, so perhaps they are no angelic after all). So, Spirit-inspired use of other languages seems unprecedented in the Judaic background of Acts.
However, Jewish tradition certainly affirmed Spirit-filled prophecy. For example, consider 1 Samuel:
Afterward you will go to Gibeah of God, where there are Philistine officials. When you enter the town, you will meet a company of prophets coming down from the high place. They will have harps, tambourines, flutes, and lyres, and they will be prophesying. 6 Then the Spirit of the Lord will rush upon you and you will prophesy with them. You will be changed into a different person. When these signs have taken place, do whatever your hand finds to do, for God will be with you. 1 Samuel 10:5-7
Could this speaking in tongues have been borrowed from non-Jewish cultures? As Craig Keener points out:
Many scholars think that the early Christian experience of tongues originated in such magical syllables or in unintelligible ecstatic speech, attested in both Egypt and Greece. The extant early Christian understandings of the experience, however (in Luke and Paul), do not reflect this background, and the experience probably (as Luke suggests) initially predates the expansion of Christianity into a Diaspora setting where such a background could make sense.
In short, God-empowered speaking in tongues, even if interpreted liberally, was unusual in the ancient world. However, it is central to Acts and the early church. This kind of speaking in tongues is even attested to by church fathers. For example, Irenaeus (c. 130 – 202 AD) wrote:
In like manner we do also hear many brethren in the Church, who possess prophetic gifts, and who through the Spirit speak all kinds of languages, and bring to light for the general benefit the hidden things of men, and declare the mysteries of God . . . . Her. 5.6.1
A Reversal of Babel
Many people (including scholars and commentators, current and ancient) understand Acts 2 as a reversal of the Babel story and believe that Luke patterned his narrative after it. The allusion is not immediately clear but there are some indications. The table of nations in Genesis 10 (shortly preceding the Babel narrative) seems to inform the list of nations in Acts 2. Acts 2 speaks of spreading tongues and confusion, using terms that sound similar to the confusion of tongues in the Babel narrative. More importantly, whether the author makes a textual allusion or not, the theological inference seems justified. Let’s read the Babel story.
The whole earth had a common language and a common vocabulary. . . . Then they said, “Come, let’s build ourselves a city and a tower with its top in the heavens so that we may make a name for ourselves. Otherwise we will be scattered across the face of the entire earth.”
But the Lord came down to see the city and the tower that the people had started building. And the Lord said, “If as one people all sharing a common language they have begun to do this, then nothing they plan to do will be beyond them. Come, let’s go down and confuse their language so they won’t be able to understand each other.”
So the Lord scattered them from there across the face of the entire earth, and they stopped building the city. That is why its name was called Babel—because there the Lord confused the language of the entire world, and from there the Lord scattered them across the face of the entire earth.
In Babel, God scattered nations for trying to deify themselves, paralleling Adam’s revolt and his expulsion from the garden. By contrast, the disciples at Pentecost were waiting in obedience to a divine command; instead of trying to reach heaven, they were waiting for their Lord, who had ascended to heaven, to send them the Spirit. In Gen 11:7, God descended to confound the transgressors, but at Pentecost God descends to clarify the mystery of the gospel to all people. In Genesis, God descended and scattered tongues to prevent unity; in Acts, the Spirit descends and scatters tongues to create unity across cultures and nations.
I said last time, but I will say it again. The coming of the Spirit, the story of Acts, is the beginning of the end of the world. The curse on sinful mankind is being reversed. The kingdom of God is both here and growing. The message of salvation spreads from Israel to all nations.
