Acts 2:38

It is a direct and immediate command to the crowd. It implies a radical change of mind and action, turning away from sin and turning to God. It is the initial and fundamental condition for responding to the gospel.

The passive imperative suggests that the action is performed on the person. Baptism in the New Testament is a public act of identification with Christ and his death and resurrection. The phrase 'in the name of Jesus Christ' indicates authority and identification with Him.

The preposition `eis` (εἰς) is crucial and has generated significant debate. It can mean 'for the purpose of' (indicating that baptism is a means to obtain forgiveness) or 'on the basis of' / 'in view of' (indicating that baptism is a response to forgiveness already granted or promised through repentance and faith). The broader New Testament context, where faith is consistently the means for justification, suggests that `eis` here could be causal or explanatory, i.e., 'be baptized *because* your sins are forgiven' or 'be baptized *in view of* the forgiveness of sins that comes through faith.' However, the reading 'in order to obtain forgiveness' is grammatically possible and is the basis for doctrines of baptismal regeneration. The text itself does not explicitly resolve this ambiguity, requiring consideration of other passages.

This is a clear promise. The reception of the Holy Spirit is a gift from God. The sequence in this verse associates it with repentance and baptism. Other passages in Acts show that the Spirit can be received before water baptism (Acts 10:44-48), suggesting that the sequence here is descriptive of this particular occasion, not prescriptive for all.

Patristic

The Church Fathers commented extensively on Acts 2:38, seeing in this verse the apostolic foundation of Christian baptism. John Chrysostom, in his Homilies on the Acts of the Apostles (Homily VII, PG 60, 60-68), comments directly on this passage and underscores that Peter demands two things: repentance (μετάνοια) and baptism in the name of Jesus Christ. For Chrysostom, the remission of sins is the proper effect of baptism, and the gift of the Holy Spirit constitutes an additional grace bestowed upon those who have validly received the sacrament. He emphasizes that sincere repentance is an indispensable condition for baptism to produce its effect. Tertullian, in his treatise On Baptism (De Baptismo, chs. 1 and 7-8, CSEL 20), is among the first to systematize baptismal doctrine from this text, asserting that the baptismal water, sanctified by the Spirit, is the vehicle of the remission of sins. Cyril of Jerusalem, in his Mystagogical Catecheses (Catecheses II and III, PG 33, 1077-1100), develops the theology of baptism as death and resurrection with Christ, explicitly linking Acts 2:38 with Christian initiation and the reception of the Spirit in confirmation. In all these authors, faith and repentance are presupposed as prior and inseparable dispositions for the sacramental efficacy of baptism.

Reformed

The Reformed tradition, following Calvin, interprets `eis` as 'on the basis of' or 'in view of' the remission of sins, which is obtained by faith and repentance. Baptism is seen as an outward sign and seal of an inward reality (justification by faith and regeneration by the Spirit) that has already occurred or is occurring. The reception of the Holy Spirit is considered to occur at the moment of saving faith, not necessarily at water baptism. Baptism is an act of obedience and a public declaration of faith.

Interpretive tension: The tension within the Reformed system arises in reconciling the explicit sequence of 'repent and be baptized... for the forgiveness of sins' with the doctrine of justification by faith alone (sola fide) and the reception of the Spirit at the moment of conversion, which is often presented as prior to baptism. It requires a careful interpretation of `eis` that does not contradict the primacy of faith.

Arminian

The Arminian tradition, like Wesley, emphasizes the importance of repentance and faith as conditions for salvation. Baptism is seen as a divinely ordained means of grace, an act of obedience that seals and confirms the forgiveness of sins and the reception of the Holy Spirit. While not necessarily considering it the *only* moment of regeneration, baptism is a vital step in the conversion experience and Christian life, where God actively works. The sequence of Acts 2:38 is seen as a normative pattern for conversion, but not in a rigid way that excludes prevenient grace or the work of the Spirit before baptism.

Interpretive tension: The tension within the Arminian system is how to maintain the importance of baptism as a means of grace and a step for the forgiveness of sins, without falling into a view that makes it absolutely indispensable for salvation, which could conflict with the universality of prevenient grace and the possibility of salvation by faith before the opportunity to be baptized.

Contemporary

Some contemporary traditions (e.g., Churches of Christ) interpret `eis` as 'in order to obtain' or 'for the purpose of obtaining,' making baptism an indispensable salvific act for the remission of sins and the reception of the Holy Spirit. Others (e.g., Oneness Pentecostals) also emphasize baptism in the name of Jesus as the only valid and essential baptism for salvation. Most contemporary evangelicals, however, view baptism as an outward symbol of an inward reality (faith and repentance) and an act of obedience, but not as the means by which salvation or the Holy Spirit is obtained, based on a broader reading of the New Testament.
