Do Household Baptisms in Acts support Infant Baptism?

It’s no secret that one of the most significant differences between different churches is how they examine the question of “infant baptism.” While most historic churches baptize infants, e.g. Roman Catholics, Orthodox Christians, Lutherans, etc., those following the heritage of the radical reformation including Baptists and most evangelicals, insist on the cognitive assent of the baptized. That is, they believe one must have sufficient understanding of the Gospel and make a conscious choice to be baptized.

This question reaches beyond mere church practice into the heart of how we understand God's covenant relationship with His people across the ages. The question also hinges no how baptism is understood. That is to say, is baptism something we do for God in response to being saved, or is it God’s work in us, a gift through which God can create and nourish our faith, unite us to Christ, and make us full participants in His body (the church). To answer that question, I’d simply ask you to look up every verse about baptism in the New Testament. Ask yourself, what does each verse say baptism does when it happens? The fact is, the idea that baptism is a mere public profession of faith has no historic viability. It’s an innovation largely born in the post-reformation era. You won’t find it described that way anywhere in the Bible. While Baptist churches tend to decry “tradition” and deny it’s binding force, the truth is that most Baptists rely far more on their custom and tradition with respect to baptism, altar calls, and even their worship practices, than they derive such ideas and practice from Scripture.

When Peter proclaimed that God's promise was "for you and your children and for all who are far off" (Acts 2:39), what did he mean? Did this include infants, or was it a promise that was reserved only for “your children” provided they’d reached an age of accountability/understanding? To truly answer that question, we need to look at more than the immediate context of Acts. What we need to ask is how would this first generation of Jewish Christians understood baptism as the sign of the new covenant?

The Promise of the Spirit: Echoing Abraham's Covenant

Peter's declaration in Acts 2:39 that "the promise is for you and your children and for all who are far off—for all whom the Lord our God will call" establishes a profound theological connection to God's covenant with Abraham. The Greek phrase "ὑμῖν γάρ ἐστιν ἡ ἐπαγγελία καὶ τοῖς τέκνοις ὑμῶν" (for to you is the promise and to your children) mirrors the language of covenant inclusion found in Genesis 17:7: "And I will establish my covenant between me and you and your offspring after you throughout their generations for an everlasting covenant."

This is no accidental parallel. The Hebrew term זֶרַע (zera) in Genesis 17:7 for "offspring" encompasses both individual and collective meanings, spanning all future generations. Similarly, Peter's use of τέκνοις (teknois) in Acts extends the promise intergenerationally. The verbal echo is deliberate, establishing continuity between what God promised Abraham and what He now offers through Christ.

When we examine the context of Peter's sermon, this connection becomes even clearer. He had just reminded his Jewish audience of "the promise of the Holy Spirit" (Acts 2:33), which links directly to God's promise to Abraham that "in you all the families of the earth shall be blessed" (Gen 12:3). Paul later identifies this blessing specifically as "the promise of the Spirit through faith" (Gal 3:14).

 

The theological symmetry is striking—what began with Abraham finds its fulfillment in Pentecost.

Baptism as the Fulfillment of Circumcision

Colossians 2:11-12 provides essential insight into understanding baptism as the typological fulfillment of circumcision: "In him also you were circumcised with a circumcision made without hands, by putting off the body of the flesh, by the circumcision of Christ, having been buried with him in baptism, in which you were also raised with him through faith."

The Greek construction here reveals remarkable connections. Paul uses the phrase "ἐν τῇ περιτομῇ τοῦ Χριστοῦ" (in the circumcision of Christ) followed immediately by "συνταφέντες αὐτῷ ἐν τῷ βαπτισμῷ" (having been buried with him in baptism). This syntactical proximity creates a deliberate parallel—baptism functions as the "circumcision of Christ."

The connection gains additional significance when we consider that Luke, the author of Acts, was Paul's traveling companion. Luke's presentation of baptism in Acts almost certainly reflects this same theological understanding that Paul articulates in his epistles.

This relationship between circumcision and baptism explains why Peter, immediately after his Pentecost sermon, commands his hearers to "Repent and be baptized every one of you" (Acts 2:38). Just as circumcision marked entrance into the Abrahamic covenant community, baptism now marks entrance into the new covenant community in Christ.

Household Baptisms: Continuing the Covenant Pattern

The narrative of Acts presents multiple instances of household baptisms that parallel the household circumcision pattern established in Genesis 17. Consider these examples:

Lydia: "After she was baptized, and her household as well..." (Acts 16:15)

The Philippian jailer: "And he was baptized at once, he and all his family" (Acts 16:33)

Cornelius: "He commanded them to be baptized in the name of Jesus Christ" (Acts 10:48, after the Holy Spirit fell on "all who heard the word," v.44; see also 11:14)

Crispus: "Crispus, the ruler of the synagogue, believed in the Lord, together with his entire household" (Acts 18:8)

The Greek term οἶκος (oikos) used in these passages signifies the entire household unit, including all members under the authority of the household head. This perfectly parallels Genesis 17:12-13, where Abraham was commanded to circumcise "every male throughout your generations, whether born in your house or bought with your money."

The pattern is consistent: just as the Old Testament covenant sign was applied to entire households, so too is the New Testament covenant sign. The theological continuity is preserved while the sign itself is transformed and expanded.

Infant Baptism: Participating in the New Covenant

Discussions about infant baptism often become trapped in speculation about whether infants were present in the household baptisms recorded in Acts. This approach, however, is an argument from silence. We can no more prove that infants were present in these households than someone might try to prove that someone must’ve preached to each person in the households mentioned and each person came to a decision for themselves to be baptized. The text says neither—thus, the way the “household baptisms” are often evoked in discussions pertaining to infant baptism vs. believers baptism misses the point. It misses the deeper theological connection between circumcision and baptism as covenant signs.

The Greek term βαπτισθήτω (baptistheto) in Acts 2:38 appears as an aorist passive imperative, indicating baptism as something received rather than achieved. This grammatical form aligns perfectly with the passive nature of circumcision in Genesis 17, where infants received the covenant sign without cognitive participation.

Consider the theological implications: The covenant with Abraham explicitly included eight-day-old infants (Gen 17:12). If baptism fulfills and replaces circumcision as the covenant sign—and if the new covenant is more inclusive than the old, extending to women, Gentiles, and people of all ages—it would create a strange theological regression to suddenly exclude infants from receiving this sign.

The early church understood this connection. Origen (c. 185-254 AD) wrote: "The Church received from the apostles the tradition of giving baptism even to infants" (Commentary on Romans 5:9). The Greek term "παράδοσις" (paradosis) used here specifically refers to apostolic tradition handed down. Irenaeus in Against Heresies wrote similarly, seeming to indicate that Jesus had reached an age of mastery when He was baptized, not that we might imitate him by being his age (appx. 30) to be baptized, but to recognize his spiritual mastery becomes ours, we receive the same Spirit in baptism, even if we’re infants:

“Being thirty years old when He came to be baptized, and then possessing the full age of a Master, He came to Jerusalem, so that He might be properly acknowledged by all as a Master. For He did not seem one thing while He was another, as those affirm who describe Him as being man only in appearance; but what He was, that He also appeared to be. Being a Master, therefore, He also possessed the age of a Master, not despising or evading any condition of humanity, nor setting aside in Himself that law which He had appointed for the human race, but sanctifying every age, by that period corresponding to it which belonged to Himself. For He came to save all through means of Himself — all, I say, who through Him are born again to God — infants, and children, and boys, and youths, and old men. He therefore passed through every age, becoming an infant for infants, thus sanctifying infants; a child for children, thus sanctifying those who are of this age, being at the same time made to them an example of piety, righteousness, and submission; a youth for youths, becoming an example to youths, and thus sanctifying them for the Lord. So likewise He was an old man for old men, that He might be a perfect Master for all, not merely as respects the setting forth of the truth, but also as regards age, sanctifying at the same time the aged also, and becoming an example to them likewise. Then, at last, He came on to death itself, that He might be the first-born from the dead, that in all things He might have the pre-eminence, Colossians 1:18 the Prince of life, Acts 3:15 existing before all, and going before all.” (Ante-Nicene Fathers, 1:391, bold text added).

One might re-phrase Irenaeus’ argument as follows. If there’s any concern that one has not attained sufficient knowledge, understanding, or mastery to be baptized, don’t we all lack a full understanding of the mystery of salvation, the mystery of baptism? Jesus had a full mastery, even having attained the age of “mastery” (as understood in his culture) not that we must become masters as well, but so that he could enter the water on our behalf, so His infinite mastery and understanding might be ours not by cognitive ascent, but by our participation in the mystical union we have in Christ when we receive baptism, when we receive His gift in faith. This faith, a simple trust that even an infant exhibits when he nurses at his mother’s breast, is sufficient for our salvation. After all, the faith of Christ likewise overcomes our deficiencies of faith (see Galatians 2:20).

The Spirit's Call Transcends Age

Peter's statement that the promise is "for all whom the Lord our God will call" (Acts 2:39) uses the Greek perfect tense in "κέκληκεν" (keklēken), emphasizing God's completed action with continuing results. This grammatical choice underscores that God's call precedes and enables our response, rather than being contingent upon it.

This understanding corresponds perfectly with the reality of circumcision, which was administered to infants before they could possibly understand its significance. The covenant sign preceded covenant understanding—a powerful testimony to the priority of divine grace over human response.

When we recognize baptism as the fulfillment of circumcision, we see that both signs function as visible words of God's promise—tangible declarations of His covenant commitment that precede our understanding and response. Just as an infant received circumcision as a mark of covenant identity long before understanding it, so too can an infant receive baptism as the sign of God's promise, with understanding to follow through faith formation within the covenant community.

Baptism and Faith Formation

The household pattern of baptism reminds us that faith is nurtured in community, particularly in families. When entire households were baptized, it established a context for ongoing faith formation. Parents and household heads were expected to instruct their households in the meaning of baptism and the content of faith—just as Abraham was commanded to instruct his household in the ways of the Lord (Gen 18:19).

This pattern of instruction following the covenant sign parallels the sequence in Deuteronomy 6:4-9, where the instruction to teach children diligently comes after the establishment of the covenant relationship. Similarly, in the Great Commission, Jesus commands to baptize and then to teach "all that I have commanded you" (Matt 28:19-20).

Divine Initiative and Human Response

The theological continuity between circumcision and baptism highlights that salvation is entirely God's work. The Hebrew concept of בְּרִית (berit/covenant) always emphasizes divine initiative and grace. God established His covenant with Abraham while Abraham was passive, even asleep (Gen 15:12-18). Similarly, in baptism, God acts first, claiming us as His own not because of our understanding or decision, but because of His gracious promise.

This doesn't diminish the importance of faith—rather, it properly orders the relationship between divine action and human response. Faith is always a response to God's prior grace, never its prerequisite. Our faith undoubtedly must take hold of the promises the Word of God attaches to Baptism, but faith does not merit these promises. Faith simply receives them. Just as an infant trusts his mother, and Jesus elsewhere praises childlike faith as idyllic, the faith that we need to receive the gift of baptism iss’t about cognitive mastery. After all, as Irenaeus pointed out, Jesus’ mastery of every mystery suffices for what we lack in our own understanding. What’s important isn’t our ability to understand, but our essential ability to receive the gift. How could anyone deny that to children, particularly when it’s these whose faith we’re called to imitate? (Matt 18:3; Mark 10:14; Luke 18:17)
