When Peter stood up at Pentecost, his audience was entirely Jewish. What did they hear when he declared that "the promise is for you and for your children and for all who are far off, everyone whom the Lord our God calls to himself" (Acts 2:39)? What they heard would have immediately governed their covenant practice, including whether they baptized their infants.
Peter's words identify three groups. Many interpreters today read "those who are far off" as Gentiles or "your children" as spiritual descendants. But the decisive question is not how we read these words now, with the benefit of progressive revelation; it is how the Jews heard them then—before Cornelius, before the Jerusalem Council—within the covenantal framework they had always known. And remarkably, Acts gives us the evidence to answer that question. Their subsequent behavior reveals their understanding.
This paper argues that the Jewish Christians at Pentecost understood Peter's three groups as follows:
- You—the Jews standing before him
- Your children—their physical offspring
- Those who are far off—Jews scattered among the nations
As we will see, the narrative of Acts demonstrates that this was indeed their initial understanding. They were incomplete in their reading of the third group—"those who are far off" ultimately included Gentiles, as the Cornelius episode would reveal. But they were correct in their reading of the second group—"your children" meant exactly what every Jew would have understood: their offspring, the next generation of the covenant community. We know this because no corresponding revelation ever corrected their understanding of children. The correction that came addressed only the scope of adult entry into the covenant, never the status of children within it.
The book of Acts demonstrates that the Jewish Christians understood "those who are far off" as scattered Israelites, not Gentiles—proven by their behavior and their shock at Cornelius's conversion. If they heard "those who are far off" in traditional Jewish covenant categories, they would have heard "your children" the same way. The later revelation that Gentiles were included addressed adult entry into the covenant—it never revised the status of children.
Every line of scriptural evidence—behavioral, narrative, practical, and epistolary—converges on the same conclusion: the apostles understood and practiced infant baptism as covenant continuity.
The Deuteronomic Template
Peter's threefold structure was not novel. His Jewish audience would have recognized it immediately from Deuteronomy 30, the great covenant renewal passage that promised Israel's restoration after exile:
When all these things come upon you ... and you call them to mind among all the nations where the LORD your God has driven you, and return to the LORD your God and obey his voice, according to all that I command you today, you and your children, with all your heart and with all your soul, then the LORD your God will restore your fortunes ... and gather you again from all the peoples where the LORD your God has scattered you. If any of you are driven out to the farthest parts under heaven, from there the LORD your God will gather you. (Deut. 30:1–4, emphasis added)
The parallel is striking:
Peter's Jewish audience would not have heard new covenantal categories. They heard him announcing the fulfillment of what Moses had promised—and Moses had explicitly included children.
But the parallel goes deeper. Deuteronomy 30 continues with a promise that sounds remarkably like Jeremiah's New Covenant: “And the LORD your God will circumcise your heart and the heart of your offspring, so that you will love the LORD your God with all your heart and with all your soul, that you may live" (Deut. 30:6, emphasis added).
Here is the promise of heart transformation—the same promise Jeremiah would later elaborate as the law "written on hearts" (Jer. 31:33). Yet notice what Deuteronomy explicitly includes: the heart of your offspring (Hebrew: zar'ekha). The promise of heart circumcision is multigenerational. God pledges to transform not only the hearts of those who hear, but the hearts of their children.
The Jews at Pentecost knew this text. When Peter declared that the promise was for them, their children, and those far off, they heard the echo of Moses. And when the Spirit fell—the Spirit who circumcises hearts and writes the law within—they understood this as the fulfillment of what Deuteronomy 30 had promised. That promise had always included their offspring.
The Jeremiah 31 Objection Preempted
Before examining the historical evidence from Acts, we must address the primary Baptist objection—the appeal to Jeremiah 31. Baptists argue that the new covenant described there is fundamentally different from previous covenants. They point to Jeremiah's promise that all covenant members will "know the LORD, from the least to the greatest" (Jer. 31:34), arguing that this excludes infants who cannot yet demonstrate such knowledge.
But this objection overlooks what Deuteronomy 30 had already established. The promise of heart transformation—which Jeremiah elaborates—was given centuries earlier by Moses, and it included offspring. If Baptists claim Deuteronomy 30 is prophetic of the new covenant (and they must, since heart circumcision is the essence of new covenant blessing), then they must reckon with the fact that this new covenant prophecy explicitly includes children.
Jeremiah 31 does not introduce a new principle that excludes offspring; it elaborates a promise that had always included them. This requires us to read Jeremiah 31 according to the ordinary function of covenantal speech in Scripture. Covenant promises and obligations are frequently announced to the covenant community in comprehensive, adult-capacity language—as is typical of covenantal and prophetic speech—even when that language cannot yet be fulfilled by all members. Such language describes the intended character and maturity of covenant life rather than serving as a prerequisite that restricts covenant membership to those already capable of its full realization.
What then does "from the least to the greatest" mean? Baptists read it as describing the composition of the new covenant—every single member, without exception, will personally know God. Since infants cannot yet "know the LORD," they argue, infants cannot be covenant members. But this reading proves too much. Jeremiah also says, "no longer shall each one teach his neighbor." If needing to be taught disqualifies someone from covenant membership, then Baptists have a problem—they still teach their members. Every church has pastors, discipleship, and instruction. Clearly the phrase does not mean that teaching ceases in the new covenant.
The better reading is that Jeremiah describes the democratization of access to God, not a prerequisite for membership. Under the old arrangement, knowledge of God was mediated through a hierarchy—priests and prophets possessed access that ordinary Israelites lacked. The new covenant promise is that this mediation gives way to direct access through the Spirit poured out on all flesh. It describes what will characterize the renewed community, not a prerequisite that must be demonstrated before one may receive the covenant sign.
The pattern throughout Scripture is consistent: cognitive covenant commands describe what characterizes adult covenant members without excluding children from covenant membership and its sign. "Circumcise your hearts" (Deut. 10:16) was commanded to adults who could understand it; eight-day-old infants still received circumcision. "Hear, O Israel" (Deut. 6:4) was addressed to those who could hear; their infants were still covenant members. "They shall all know me" (Jer. 31:34) describes what characterizes the renewed covenant community; it does not specify that only those who already demonstrate this knowledge may receive the covenant sign.
The question is not whether heart transformation is essential to the new covenant—it is. The question is whether heart-transformation language functions as a prerequisite for receiving the covenant sign or as a promise that God will fulfill in the covenant community across generations. Deuteronomy 30:6 settles the matter: it is a promise, and the promise includes offspring.
The Evidence from Acts
The theological argument from Deuteronomy 30 is significant, but the historical evidence from Acts is decisive. We can actually test how the Jewish Christians understood Peter's words by examining their subsequent behavior.
When persecution scattered the church from Jerusalem, those who went out carried the gospel beyond the city—but only to Jews. Acts records that they preached "to no one except Jews only" (Acts 11:19). This detail is crucial. It demonstrates that the early church understood "those who are far off" as scattered Israelites, not Gentiles. Their missionary practice confirms that they were still operating within traditional Jewish covenant categories.
This is the key inference: if the Jewish Christians understood "those who are far off" as scattered Jews rather than as Gentiles or spiritual offspring, then they would have understood "your children" in the same traditional Jewish covenant categories—as their physical offspring who belonged to the covenant community and should receive the covenant sign. Some Reformed Baptists argue that "your children" should be understood spiritually—as the elect—appealing to passages like John 6:45. But this argument faces a decisive problem: the Jews demonstrably did not hear Peter this way. If "your children" meant spiritual offspring, then "those who are far off" should also be spiritual (elect Gentiles). You cannot selectively spiritualize one element while leaving another in its covenantal sense. They heard the whole statement through Jewish covenantal ears. The appeal to John 6:45 may work as a theological interpretation, but it fails as a historical claim about how these Jews heard Peter in 30 AD.
The Cornelius episode confirms this reading. In chapter 10, God gives Peter a vision—three times—declaring that what God has made clean, Peter must not call unclean. When messengers from Cornelius arrive, the Spirit tells Peter to go without hesitation. Yet even then, Peter struggles to understand what God is doing. When the Spirit falls on Cornelius's household, Peter is astonished. In chapter 11, the Jerusalem church rebukes him for associating with uncircumcised men.
Peter's defense is revealing: "If then God gave the same gift to them as he gave to us when we believed in the Lord Jesus Christ, who was I that I could stand in God's way?" (Acts 11:17).
Peter admits that he had been standing in God's way. This is a retrospective acknowledgment that his earlier understanding had been incomplete. He had heard Acts 2:39 in traditional Jewish covenant categories—and he was wrong about the scope of "those who are far off."
The same logic applies to the qualifying phrase, "everyone whom the Lord our God calls to himself." Some read this as limiting the promise to those who are effectually called—that is, the regenerate elect. On this reading, only those who respond savingly to God's call are truly in view, which would exclude infants.
But this interpretation faces the same problem as the spiritual reading of "your children": it does not match how the Jews actually heard Peter's words. The Jewish Christians understood Peter within their existing covenantal framework—the framework they had inherited and lived within their entire lives. They would have heard "whom the Lord our God calls" as describing how God gathers his people into this new phase of covenant history—not as a restriction that would exclude their children from the covenant community.
Consider the covenantal logic. God calls; his people respond; the covenant community consists of those who answer that call together with their households. This is precisely the pattern we see throughout Acts—entire households entering the covenant when the head of household believes. The "call" explains how adults enter the covenant; it does not negate the covenantal structure that has always included believers and their children together.
If the qualifying clause meant "only the regenerate," we would expect the apostles to have clarified this—especially given how easily the Jews would have misunderstood. But no such clarification appears. The Jews heard the promise covenantally, and nothing in the subsequent narrative suggests they were wrong to do so.
But notice what the Cornelius revelation corrected: Peter's understanding of Gentile inclusion. What it did not correct—what is never mentioned, debated, or even hinted at—is the status of children. If the apostles' covenantal understanding of "your children" was also mistaken, the Cornelius moment was the natural point to address both errors. Yet only one correction appears.
The Household Principle After Cornelius
If the Cornelius revelation had corrected the covenantal understanding of children—if the apostles now understood that only professing believers should receive baptism—we would expect to see this reflected in subsequent baptismal practice. Instead, we find the opposite: household baptisms continue throughout Acts.
After Cornelius, Luke records:
- Lydia's household—"She was baptized, and her household as well" (Acts 16:15)
- The Philippian jailer's household—"He was baptized at once, he and all his family" (Acts 16:33)
- Crispus's household—"Crispus, the ruler of the synagogue, believed in the Lord, together with his entire household" (Acts 18:8)
- Stephanas's household—"I did baptize also the household of Stephanas" (1 Cor. 1:16)
The Greek term oikos ("household") carries deep covenantal resonance—translating the Hebrew bayit, the household unit that received covenant blessings and obligations together from Abraham onward (Gen. 17:11–13).
This household principle continues unbroken through Acts. The apostles did not begin baptizing only professing individuals after Cornelius; they continued baptizing households. If the Cornelius revelation had taught them that children should no longer be included until they could profess faith, Luke's repeated mention of household baptisms would be inexplicable.
Baptists often respond that these households may have consisted entirely of adults, or that all members of the household believed. But this misses the point. The very category of household baptism reflects traditional Jewish covenantal thinking. If the apostles had come to understand baptism as the sign of individual profession only, they would have baptized believers, not households. The continued use of household language demonstrates that the covenantal framework remained intact.
The Epistolary Confirmation
If the apostles had corrected the Jewish understanding of "your children" from physical to spiritual, they would have needed to reinforce that correction in their subsequent teaching to the churches. Instead, we find the opposite—they continue using covenantal family language without any clarification that its meaning has changed.
Consider the evidence: "For the unbelieving husband is made holy because of his wife, and the unbelieving wife is made holy because of her husband. Otherwise your children would be unclean, but as it is, they are holy" (1 Cor. 7:14).
Paul uses the same covenantal holiness language—hagios, "holy" or "set apart"—that described Israel's covenant status throughout the Old Testament. And he applies it to the physical children of believers. If "your children" in Acts 2:39 now meant spiritual offspring rather than physical descendants, Paul's continued use of this language would have been catastrophically confusing.
"Children, obey your parents in the Lord, for this is right." (Eph. 6:1)
"Children, obey your parents in everything, for this pleases the Lord." (Col. 3:20)
Paul addresses children directly as members of the covenant community—"in the Lord"—recipients of apostolic instruction with obligations flowing from their covenant status.
Paul is writing to churches that include both Jewish and Gentile believers. If the covenantal understanding of children had been corrected—if "your children" now meant "the elect" rather than "your offspring"—Paul's continued use of the old covenantal language would be inexplicable. You do not correct a fundamental misunderstanding about covenant membership and then continue using the same terminology that caused the confusion.
Unless, of course, there was no confusion to correct.
The Argument from Silence
What is absent from the New Testament is just as telling as what is present. The great controversies concern whether to include Gentiles, never whether to exclude children. Had the apostles overturned the Abrahamic pattern, it would have provoked outrage, required explanation, and left a record.
For two thousand years, children of believers had received the covenant sign by God's explicit design (Gen. 17:7). To overturn this would have been a seismic shift—far more significant than Gentile inclusion, which the prophets had anticipated.
Yet Acts records no such controversy. We find extended debates about circumcision requirements for Gentiles (Acts 15), fierce resistance to eating with uncircumcised men (Acts 11:2–3), and careful deliberation about what to require of Gentile converts. But not a single word about excluding children from the covenant community.
The silence is best explained by continuity, not omission. The controversies of the early church concerned the horizontal expansion of the covenant (to Gentiles)—never its vertical contraction (excluding children). If both changes had occurred, we would expect both to leave traces. Only one does.
Conclusion
The new covenant did not narrow the scope of God's promises; it expanded them. The children were already in. The surprise was that the Gentiles were, too. Even if the early Jewish Christians initially misunderstood, their covenantal reading would have led them to baptize their infants—and the Cornelius revelation, which corrected their understanding of Gentile inclusion, never touched the status of children.
Deuteronomy 30 had promised that God would circumcise the hearts of his people and their offspring. Jeremiah 31 elaborated this promise as a new covenant with the law written on hearts. At Pentecost, Peter announced that this promise had arrived—for those present, for their children, and for all whom the Lord would call from the farthest parts of the earth.
From the day of Pentecost, Jewish believers would have continued the practice embedded in their covenantal DNA: including their children in the covenant community and marking them with the covenant sign. This was not theological innovation but covenant fidelity—trusting the same God who had promised to circumcise the hearts of his people and their offspring.
