When the Ethiopian official asked Philip what could stop him from being baptized, the answer was simple faith in Christ (Acts 8:36–37), and the method was equally clear: “they went down both into the water, both Philip and the eunuch; and he baptized him… they were come up out of the water” (Acts 8:38–39). Baptism throughout the New Testament was by immersion — a full going-under, not a symbolic sprinkle or a few drops on the forehead.
Unless otherwise noted, Bible texts in this article are quoted from the King James Version (KJV).
What the Word Itself Means
The Greek word translated “baptize,” baptizo, literally means to dip, plunge, or immerse. Even the location details in the Gospels confirm this meaning: John baptized “in AEnon near to Salim, because there was much water there” (John 3:23) — a detail that would be irrelevant if baptism only required a small vessel of water for sprinkling. Jesus Himself, when baptized, “went up straightway out of the water” (Matthew 3:16), language that only makes sense if He had first gone down into it.
A Burial and a Resurrection
Paul explains why the method matters so precisely: “Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death? Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life” (Romans 6:3–4). Going under the water pictures burying our old life; coming back up pictures rising to a new one in Christ. The symbol only works fully when the water covers completely — a burial, not a splash, matching the full death-and-resurrection reality it represents.
A Decision, Not Just a Ceremony
This is why Adventists practice baptism by immersion for those old enough to personally understand and choose it — it is meant to follow genuine belief and repentance, a public declaration of a choice already made in the heart, rather than a ritual performed on an infant unable to comprehend or consent to its meaning. Jesus’ own instruction ties baptism directly to belief: “Go ye into all the world, and preach the gospel to every creature. He that believeth and is baptized shall be saved” (Mark 16:15–16) — belief coming first, baptism following as its natural, public expression.
What Baptism Represents
Baptism represents several realities at once: cleansing from sin, symbolized by washing (Acts 22:16); death to an old way of life and resurrection to a new one (Romans 6:4); and formal entrance into the body of believers, the church (1 Corinthians 12:13). Peter connects baptism to “the answer of a good conscience toward God” (1 Peter 3:21) — not the water itself washing away sin, but the inward transformation the water publicly represents.
“He that believeth and is baptized shall be saved.” — Mark 16:16
Baptism does not save on its own — faith in Christ does that. But baptism is how that faith steps out of the heart and into the open, visible for the whole world to see, following the same pattern every recorded New Testament convert followed.
Preparing for Baptism
Because baptism follows understanding and belief, preparation typically includes a period of Bible study, examining core teachings of Scripture together with someone already grounded in the faith. This mirrors Philip’s own approach with the Ethiopian official, who first “preached unto him Jesus” (Acts 8:35) before baptism ever took place. The goal is never a rushed ceremony, but a settled, informed, personal decision to follow Christ fully, symbolized permanently and publicly in the waters of baptism.
Why Age and Understanding Matter
Every baptism recorded in the New Testament follows a consistent pattern: teaching first, belief second, baptism third. The three thousand baptized at Pentecost first “gladly received his word” (Acts 2:41). The Samaritans baptized under Philip’s ministry first “believed Philip preaching the things concerning the kingdom of God, and the name of Jesus Christ” (Acts 8:12). Not a single instance in Scripture describes an infant or young child being baptized without prior understanding, because the very meaning of baptism — a personal burial of the old self and rising to new life — requires a self capable of making that choice.
Household Baptisms Reconsidered
Some point to “household” baptisms, such as the Philippian jailer’s (Acts 16:33), as evidence for infant baptism. But the same passage describes the jailer’s entire household hearing “the word of the Lord” and “believing in God” (Acts 16:32, 34) before baptism — language that assumes those baptized were capable of hearing and believing, not infants incapable of either. The text itself provides no evidence of infants present, let alone baptized without understanding.
A Public Testimony to the Church and the World
Baptism also functions as a testimony — both to the watching church and to the wider community — that a specific, identifiable person has chosen to follow Christ. Paul describes this public dimension when he writes of believers being “baptized into one body” (1 Corinthians 12:13), formally joining the visible community of faith. Far from a private, individual transaction, baptism marks a person’s entry into a covenant community that now shares responsibility for their spiritual growth and accountability.
A Beginning, Not an Ending
Baptism is never presented in Scripture as a finish line, but as a starting point for a lifetime of growth. Paul instructs believers to continue what baptism symbolically began: “Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord” (Romans 6:11) — an ongoing, daily choice to live out what the water once pictured in a single, unforgettable moment.
That daily choice, sustained faithfully over a lifetime, is the true measure of what baptism was always meant to launch.
Anyone ready to make that choice, having counted the cost honestly, is invited to step into the water just as the Ethiopian official once did on a desert road, asking for nothing more than the chance to follow Christ fully.
The invitation costs nothing but sincerity, and it changes everything that follows.
