Baptism Classes: What Matthew 28:18-20 Actually Teaches
Short answer: Baptism classes are teaching sessions that prepare a person to be baptized with understanding rather than mere routine. They rest on the risen Jesus' words in Matthew 28:18-20, where he grounds the church's mission in his own authority and commands his followers to make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, and teaching them to observe all that he commanded. A faithful class explains what baptism is, who may receive it, what it signifies, and how it relates to repentance, faith, and life in the church. It does not add a requirement Scripture never made, and it does not turn preparation into a second gospel.
Why Jesus' authority comes before any baptism lesson
Matthew 28:18-20 opens with a declaration before it gives a command. The risen Jesus says, in the supplied text, that all authority has been given to him in heaven and on earth. Everything that follows in the passage flows from that authority: the sending, the baptizing, the teaching, the promise of his presence. A baptism class that begins with technique or tradition rather than with Christ's authority has started in the wrong place. The one who commands baptism is the one who has been given all authority, and that means the practice of baptism is not a church invention, nor is it a cultural rite that congregations may reshape at will.
This matters for how a class is taught. If the authority behind baptism is merely the custom of a denomination, then the class becomes an explanation of that custom. If the authority behind baptism is the risen Christ, then the class becomes an explanation of his command. The difference shows up in what gets said and what gets left unsaid. A class rooted in Matthew 28:18-20 must keep returning to the one who spoke these words, because the command to baptize is his command and not the church's preference. The teacher is not free to soften it, expand it, or replace it with something more comfortable.
Notice also the sequence in the text. Authority, then going, then baptizing, then teaching. Baptism sits inside a larger mission, not outside of it or above it. A class that treats baptism as an isolated event, disconnected from disciple-making and ongoing teaching, has divided what Jesus joined together. The command is not merely to baptize but to make disciples, and baptism is one part of that making. This means a baptism class is properly a discipleship class, and the preparation should aim at the whole life of following Jesus, not merely at a single ceremony on a single day.
Teachers should therefore be honest about what they can and cannot do. They can explain the command, the wording, the meaning, and the expectations. They cannot manufacture faith in the one being baptized, and they cannot guarantee that the baptism will produce a particular experience. The class prepares the mind and the conscience, but the Lord is the one who gives the growth. Keeping Christ's authority central also keeps the teacher humble, because the same Lord who commands baptism is the Lord who searches the heart and knows whether the profession is genuine.
Making disciples of all nations, not only of people like us
The command in Matthew 28:19 is to make disciples of all nations, and baptism is named as part of that making. Every faithful baptism class has to reckon with the scope of this commission. The risen Jesus did not restrict the mission to one ethnic group, one social class, one age, or one region. He sent his disciples to all nations. That means the church's teaching on baptism must be able to be carried across cultures and languages without losing its essential content. A class that only makes sense inside one tradition or one country has not yet understood the breadth of what Jesus commanded.
This also has a pastoral edge. If the command reaches all nations, then it reaches the person who did not grow up in the church, the person whose family never practiced any faith, and the person whose past is tangled and public. Baptism classes are often where such people first receive careful instruction, and the teacher's tone matters as much as the content. The goal is not to sort out the worthy from the unworthy, since no one is worthy on their own. The goal is to help a person understand what they are doing and to do it with a clear conscience before God.
At the same time, the breadth of the command does not mean that anything goes. Making disciples of all nations includes teaching them, and teaching implies content. A class that offers only sentiment and no instruction has not made disciples in the sense Jesus described. The nations are to be taught, and baptism is tied to that teaching. So the class must actually teach: what the gospel is, who Jesus is, what repentance means, what faith means, what the church is, and what happens in baptism. Warmth without content is not the Great Commission; it is something thinner.
Practically, this means a baptism class should be accessible to those who know almost nothing and substantial enough to challenge those who know a great deal. It should avoid assuming a lifetime of church vocabulary, and it should avoid reducing the faith to slogans. The teacher who takes Matthew 28:19 seriously will prepare material that a new believer can follow and that a mature believer can still profit from. That is a real labor, but it is the labor the command requires, and the Lord who gave the command also gives the patience to carry it out.
The trinitarian name spoken over the water
Matthew 28:19 specifies the name into which disciples are baptized: the name of the Father and of the Son and of the Holy Spirit. This is one reason baptism classes matter. The words spoken at baptism are not incidental; they identify the God into whose life and family the person is being baptized. Any class that hurries past this phrase is hurrying past something central. The phrase is also one of the clearest trinitarian statements in the New Testament, and it shapes how the church speaks about God in the very act of baptism.
Different traditions handle this phrase differently in practice. Some baptize using the full trinitarian formula exactly as Matthew records it. Others, pointing to Acts 2:38, baptize in the name of Jesus Christ. Acts 2:38 in the supplied text says, addressing the crowd, that each should repent and be baptized in the name of Jesus Christ for the forgiveness of sins. Faithful Christians have disagreed about how to harmonize these texts, and a good class should say so honestly rather than pretending the question is settled everywhere or that it does not exist.
What the class should not do is allow the disagreement to obscure the unity of the command. Whether a congregation uses the longer trinitarian formula or a shorter christological one, the baptism is administered under the authority of the same risen Lord. The important thing for the person being baptized is that they understand who is being named and why. A baptism class that explains the formula in its biblical context, and is candid about differing practices, serves the church better than one that either ignores the question or treats its own answer as the only conceivable reading.
There is also a pastoral opportunity here. The trinitarian name is not a formula to be mumbled but a confession to be understood. The Father who receives, the Son who saves, and the Spirit who applies and seals are all involved in the salvation a person is professing. Teaching this prepares the candidate to hear the words spoken over them as more than ceremony. It also guards against the idea that baptism is about the candidate's performance, since the name spoken is God's, not the candidate's.
Baptism, repentance, and the forgiveness of sins
Acts 2:38 links baptism to repentance and to the forgiveness of sins in a single sentence. Peter tells the crowd to repent and to be baptized, every one of them, in the name of Jesus Christ for the forgiveness of sins, and promises the gift of the Holy Spirit. Any baptism class that wants to be honest with the New Testament has to work through this verse carefully. It does not say that water washes away sin mechanically, nor does it separate baptism from the repentance and faith that accompany it. The verse holds repentance, baptism, and forgiveness close together.
This is where classes often go wrong in one of two directions. Some teach that baptism itself saves apart from any faith, as if the water did something automatically to a passive recipient. Others teach that baptism is only an optional public symbol with no real connection to forgiveness at all. Neither reading does justice to the way Peter speaks. The text presents baptism as the God-given response to the gospel, the point at which the repentant person publicly identifies with Christ and receives the promise. The inner reality and the outward act belong together, and the class should keep them together.
1 Peter 3:21 gives another angle. In the supplied text it says that baptism is a symbol that now saves you, not the putting away of the filth of the flesh, but the answer of a good conscience toward God, through the resurrection of Jesus Christ. This verse explicitly denies that baptism saves by removing physical dirt, and it ties the saving significance to the conscience and to the resurrection. It is a strong argument against any magical view of the water, and it is also an argument against dismissing baptism as nothing more than an empty sign.
Colossians 2:11-12 adds a further layer, speaking of a circumcision not made with hands, the putting off of the body of the sins of the flesh, and burial with Christ in baptism, in which the person is also raised with him through faith. Here again the outward act is bound to an inward reality. A baptism class that simply explains the mechanics of the service has not done its job. It must help the candidate see that the water points to a spiritual burial and resurrection, and that the faith which receives this is the faith God himself gives.
One passage, one practice, a hundred practical questions
Even when a congregation is settled on what baptism means, a class still has to answer practical questions that the text does not directly address. At what age should a person be baptized? How much must a candidate understand before the water is administered? How long should preparation last? Who may perform a baptism? Must it happen in a church building, or may it happen in a river, a pool, or a home? Scripture gives examples and principles, but it does not answer every procedural question, and a class that pretends otherwise is overreaching.
The example in Acts 8:26-39 is instructive here even though it does not settle every question. Philip is directed by an angel, meets the Ethiopian official on the desert road, explains the Scriptures to him, and baptizes him when they come to water. The narrative is spare and fast-moving, giving no indication of a long preparation process. Some traditions read this as warrant for immediate baptism upon a credible profession. Others, especially with children, prefer a longer season of instruction. Both approaches claim to honor the text, and the class should be honest that the difference is one of prudence, not of direct command.
Similarly, the New Testament does not prescribe a single mode in exhaustive detail, nor does it specify a single permissible location. Immersion has strong support in the imagery of burial and resurrection found in Romans 6:1-4 and Colossians 2:11-12, and many churches practice it for that reason. Other traditions practice pouring or sprinkling. The class should explain the congregation's practice, ground it in Scripture as far as Scripture goes, and avoid claiming more certainty than the text provides. Where the Bible is silent, the teacher should be silent too, or at least flag the difference clearly.
What the class can and should do is prepare the candidate for the questions that will follow baptism: how to continue in the teaching of the apostles, how to find a church home, how to handle failure, and how to keep growing. A baptism is a beginning, not a graduation. The teaching that Jesus commanded in Matthew 28:20 continues long after the water dries, and a well-designed class will tell the candidate this plainly so that no one is surprised when the Christian life turns out to require endurance.
What baptism classes should never promise
Baptism classes should never promise that baptism will fix a person's life, remove their temptations, heal their relationships, or guarantee a particular emotional experience. The New Testament is realistic about the Christian life, and honest teaching prepares people for difficulty rather than shielding them from it. The promise attached to the Great Commission is the presence of Christ, not the absence of trouble. A class that implies otherwise sets people up for disillusionment when the ordinary hardships of discipleship arrive, and it misrepresents the very Lord whose authority it claims to honor.
A class should also avoid promising that baptism secures salvation in a mechanical sense. The New Testament consistently joins baptism to faith and repentance, and it warns against mere outward religion. A person can be baptized and still fall away; the New Testament has examples and warnings of exactly this. Conversely, the thief on the cross was promised paradise without baptism, which should keep any teacher from making the water into a barrier that God himself does not impose. The class should teach the command seriously without turning it into a lever that controls God.
Finally, a class should not promise that baptism solves the question of assurance. Assurance rests on the finished work of Christ and the witness of the Spirit, not on the memory of a ceremony. A candidate who is anxious about whether they were sincere enough at their baptism needs the gospel, not another ritual. A good class points them to Christ's sufficiency and to the ordinary means of grace, and it refuses to make the candidate's feelings the foundation of their standing before God.
Teaching baptism without turning it into the gospel
Baptism is commanded by Christ and is not optional for those who follow him. But it is not the gospel, and it does not replace the gospel. The gospel is the good news of what God has done in Christ for sinners who cannot save themselves. Baptism is the God-given sign and seal of that good news, administered to those who repent and believe. A baptism class that keeps this distinction clear will produce candidates who understand both the seriousness of the command and the sufficiency of the Savior, and it will guard against the twin errors of treating baptism as a mere formality or as a saving work in itself.
This balance is one reason the historic churches have written out their teaching on baptism rather than leaving it to improvisation. Catechisms, confessions, and study materials exist so that the same instruction can be given faithfully across generations and locations. A baptism class is a small, local expression of that larger teaching ministry. It serves the church by handing on the apostolic faith in a form that a new believer can grasp, and it serves the candidate by giving them honest answers before they stand in the water.
Churches should also make room for the class to be more than a lecture. Candidates benefit from time to ask questions, to hear the stories of others, and to see baptism modeled in the congregation's life. A class that is merely a doctrinal monologue misses the relational dimension of disciple-making. Jesus made disciples by walking with people, and the church's preparation for baptism should reflect that pattern as far as it can, without turning the class into a social club or a test of belonging.
Above all, the class should end where the commission begins: with the authority of Christ and the promise of his presence. The candidate who is baptized is not being initiated into a human society but into the body of the risen Lord, who has promised to be with his people to the end of the age. That promise is the ground of confidence for the candidate and for the teacher alike.
Biblical fidelity check
Matthew 28:18-20 establishes that the risen Jesus possesses all authority, that his disciples are to make disciples of all nations, that baptism is administered in the name of the Father and of the Son and of the Holy Spirit, and that teaching obedience to all his commands is part of disciple-making. It does not specify the mode of baptism, the age of candidates, the length of preparation, the location, or the precise relationship between the water and the saving work of God. Those details must be settled from the wider New Testament witness and from the practice of faithful churches, and where the Scripture is silent, the teacher should not speak as if it had spoken.
A common misreading treats Matthew 28:19 as if baptism were merely a cultural ceremony that any church may adapt to any meaning it likes, on the assumption that the command is about the outward act alone. The verse will not bear this. Baptism is tied to the name of the triune God and to the making of disciples, and it is placed within the mission of the church under the authority of Christ. Another misreading treats the passage as if it settled every practical question about baptism, which it does not. The faithful teacher distinguishes what the text establishes from what prudence and the wider canon must decide, and says so without embarrassment.
Other passages that speak to Matthew 28:18-20
Baptism does not stand alone in the New Testament. Its meaning is illuminated by passages that speak of repentance, new birth, cleansing, and the believer's union with Christ in his death and resurrection. Further studies that help set Matthew 28:18-20 in context include What Does 1 Peter 1:2 Mean? Context, Theology, and Application, What Does 1 Peter 1:13 Mean? Context, Theology, and Application, What Does 1 Peter 1:15 Mean? Context, Theology, and Application, and What Does 1 Peter 1:18 Mean? Context, Theology, and Application. These passages trace the same themes of obedience, holiness, and redemption that a baptism class must handle with care.
Frequently asked questions
Do I need to take a class before I can be baptized?
Scripture does not command a formal class, and the Ethiopian official in Acts 8 was baptized after a brief explanation of the Scriptures. But Scripture does command teaching, and a class is one faithful way to provide it. Churches differ on how much preparation they require. What matters is that the candidate understands the gospel, the meaning of baptism, and the commitment being made. A class serves that goal; it should not become an extra hurdle that Scripture never imposed.
Does baptism save me?
1 Peter 3:21 says baptism is a symbol that now saves you, not the putting away of the filth of the flesh, but the answer of a good conscience toward God. The verse ties the saving significance to the conscience and to the resurrection of Christ, and it explicitly denies that the water removes physical dirt. Scripture consistently joins baptism to repentance and faith. Faithful Christians differ on how to describe the relationship, but all should agree that the water itself, apart from Christ, saves no one.
What if I was baptized but did not understand what I was doing?
Many people were baptized young or under pressure and later wonder whether it counted. The honest answer is that God is not served by anxiety about the past but by present repentance and faith. Some churches would encourage such a person to be baptized again upon a clear profession; others would not repeat baptism and would instead point to the ordinary means of grace. Both positions are held by faithful Christians. Speak with your pastors, who can help you think it through.
