We believe that baptism is an ordinance of the Lord by which those who have repented and come to faith express their union with Christ in His death and resurrection, by being immersed in water in the name of the Father and the Son and the Holy Spirit. It is a sign of belonging to the new people of God, the true Israel, and an emblem of burial and cleansing, signifying death to the old life of unbelief, and purification from the pollution of sin.
Let’s take five parts of that affirmation and look at the biblical basis for them.
- Baptism Is an Ordinance of the Lord
First, “We believe that baptism is an ordinance of the Lord . . .” What we mean by this is that the Lord Jesus commanded it—he ordained it—in a way that would make it an ongoing practice of the church. We find this most explicitly in Matthew 28:19-20: “Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you.”
So baptism is a command, and ordinance, of the Lord Jesus to be performed in making disciples until Christ returns at the end of the age.
- Baptism Expresses Union with Christ
Second, baptism “expresses union with Christ in His death and resurrection.” The clearest teaching on this is Romans 6:3-4.
Do you not know that all of us who have been baptized into Christ Jesus were baptized into his death? We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life. So the imagery of baptism is death, burial, and resurrection. Christ was buried and raised to new life.
In baptism, by faith, we are united with Christ in his death, burial, and resurrection. Baptism dramatically portrays what happened spiritually when you received Christ: Your old self of unbelief and rebellion and idolatry died, and a new you of faith and submission and treasuring Christ came into being. That’s what you confess to the world and to heaven when you are baptized.
- Baptism Is Immersion in Water
Third, we believe this expression of union with Christ in death and resurrection happens “by being immersed in water.” The clearest evidence for this are the words of Romans 6:3-4 which describe the act of baptism as burial and rising from the dead. This is most naturally understood to mean that you are buried under water and then come out of from the water to signify rising from the grave.
The word baptism in Greek means dip or immerse. And most scholars agree that this is the way the early church practiced baptism. Only much later does the practice of sprinkling or pouring emerge, as far as we can tell from the evidence.
- Baptism Is in the Trinitarian Name
Fourth, baptism means doing this immersing in the name of the Father, the Son, and the Holy Spirit. That’s what Jesus said in Matthew 28:19: “Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit.” This means that not just any immersing is baptism. There is a holy appeal to God the Father and God the Son and God the Holy Spirit to be present in this act and make it true and real in what it says about their work in redemption. There is no salvation without the Father, the Son, and the Holy Spirit. When we call on their name, we depend upon them and honor them and say that this act is because of them and by them and for them.
- Baptism Is for Believers Only
Fifth, baptism is an expression of faith and therefore only for believers. The key sentence in the Bethlehem Elder Affirmation says, “We believe that baptism is an ordinance of the Lord by which those who have repented and come to faith express their union with Christ in His death and resurrection.” So our understanding of the New Testament is that the meaning of baptism includes the fact that it is an expression of the faith of the one being baptized. It is not something that an unbeliever can do. It is not something than an infant can do. That is why we don’t baptize infants.
There are several passages that have had the greatest influence on me over the years in persuading me of the Baptist view. One of the most important is Colossians 2:11-12.
In him [Christ] also you were circumcised with a circumcision made without hands, by putting off the body of the flesh, by the circumcision of Christ [so Paul speaks of circumcision in "made-without-hands” terms. Circumcision today has meaning for the Christian, not as a physical act, but as a spiritual act of Christ in which he cuts away the old sinful body and makes us new. It is virtually synonymous with the new birth. Then he speaks of baptism], having been buried with him in baptism, in which you were also raised with him through faith in the powerful working of God, who raised him from the dead.
So the image of spiritual circumcision is closely connected with the image of baptism: “You were circumcised . . . having been baptized . . .” The old “body of flesh” was cut away in conversion; you died and rose again in baptism.
