Introduction
Before I say that this baptism is right and the other is wrong, imagine a first-century time when, in a river, an adult is going to get baptized, and he is so excited to receive Jesus as his Lord and savior. Now the same scene but jump 300 years ahead in Europe with an infant, who is sick and will die soon. Is it possible to give immersion baptism to this infant in the cold? The answer is NO. Same word—baptism—but different world. So which is right? Should we use context here to define a way of getting baptism?

So which baptism does he mean among these 78 types I listed? When we see the word itself used, there is baptizō (βαπτίζω), which is the Greek verb meaning "to dip, immerse, or submerge. " All three meanings point to one thing only: that is, full immersion.
When I say “full immersion,” as I understand it from a Pentecostal perspective, I mean baptism carried out in the New Testament sense: the believer is fully immersed in water and then brought up from the water, administered in the name of the Father, the Son, and the Holy Spirit. This understanding also assumes believer’s baptism, in which the person being baptized has consciously placed faith in Christ. The person dies, is buried, and is resurrected in Jesus Christ.
If I say this is true baptism, then you might ask why. So here you have certain listed reasons:
The first reason is because the word itself describes the verb of what to do. Secular writers used the Greek word to describe a sinking ship. This is how the word is used in Scripture (Lk. 16:24). There is a word for sprinkling also in Scripture: ῥαντισμός rantismos (1 Pet. 1:2). There is also a word for pouring in Scripture: ἐκχέω ekcheo (Acts 2:17). But neither of these words is used for baptism.
The Second Bible itself gives us certain examples of how the baptism was done. John in Matthew 3:6 was baptizing “in” the Jordan River. Also, John 3:23 says there was “much water” where John was baptizing. Much water is needed only for baptism by immersion.
The third popular reason is the symbolism that baptism presents, i.e., the death, burial, and resurrection of Jesus Christ. (Romans 6)
Also there is no mention of infants being baptized by disciples & no mention of sprinkling as well.
Also the writing of the early theologians make this argument stronger; however, it is out of the New Testament world.
1) John Calvin spoke of the mode of baptism in his Institutes: "... Yet the word ‘baptize’ means to immerse, and it is clear that the rite of immersion was observed in the ancient church” (John Calvin, Institutes of the Christian Religion, in Library of Christian Classics, trans. by F. L. Battles, ed. John T. McNeill, Louisville: Westminster John Knox Press, 1960, 1320).
2) Luther : “For this reason, I would have those who are to be baptized completely immersed in the water, as the word says and as the mystery indicates. Not because I deem this necessary, but because it would be good to give to a thing so perfect and complete a sign that is also complete and perfect. And this is doubtless the way in which it was instituted by Christ. The sinner does not so much need to be washed as he needs to die in order to be wholly renewed and made another creature and to be conformed to the death and resurrection of Christ, with whom he dies and rises again through baptism” (Martin Luther, Word and Sacrament I, in LW, vol. 35, ed., E. Theodore Bachman, Philadelphia: Fortress Press, 1960, 29).
Circumcision parallel (the big theological move)
This is the strongest argument for infant baptism, so I thought to handle it separately. In the Old Testament, infants were circumcised as part of the covenant. And in Colossians 2:11–12, Paul links circumcision and baptism symbolically. Therefore, it is logical to argue that baptism replaces circumcision, which means infants should be baptized.
This argument is theological (which is SUBJECTIVE, NOT BIBLICAL) and also not narrative.
But notice the shift: Circumcision marks ethnic covenant membership, but baptism in the New Testament marks faith-union with Christ. Paul constantly insists that the new covenant is entered by faith, not birth. So the analogy works symbolically, but it is not airtight. I don’t want to give much attention to this because the internet is full of arguments against this.
The Shift
By the 2nd century, Christianity was not bound to the walls of Jerusalem, but it spread like fire. It was spreading into cities, deserts, prisons, and homes where water was not always cooperative. The faith was the same, but the setting had changed, and settings always push practice before theology has time to put on its shoes.
The Didach, yes, the book not in your New Testament, has mention of ‘running water,’ meaning flowing water like a river or stream. If that is not available, other water may be used. Only then, if immersion is not possible, does it allow water to be poured over the head three times. I want you to focus on ‘ONLY THEN’; if the running water is not present, it does not make it a tradition to follow. Because African countries were always in need of water. So to baptize them in water is like teaching swimming lessons during a flood.
This tells us something important. Early Christians were not rigid ritualists, but neither were they careless. They adapted when they had to, not because the meaning of baptism had changed, but because circumstances sometimes refused to cooperate. Scarcity of water, missionary travel, and persecution all played a role. You baptize differently when you are hiding, moving, or living under threat. But when we talk about infant baptism, here also we find no trace of an infant getting baptized.
Entry of Infant Baptism
Around the end of the 2nd century, Christianity had reached the ends of the Roman Empire, and almost 2nd- or 3rd-generation Christians started appearing. Now the Church was no longer of only adults; the christian families were getting new members in their houses and this all raised a question the apostles never answered directly: ‘What happens to the children of believers if they die without baptism?’
Around 200 AD, we hear about this from our Brother Tertullian, not in favor but against, where he opposes this practice. He argued that baptism should be delayed until a person can understand faith and responsibility (as I said in my definition). His concern only makes sense if infant baptism was already being practiced in some communities or was spreading. But why did this infant baptism gain popularity? The reasons are simple: high infant mortality rate and persecution (which was still there).
This moment was important for the church because it marked a turning point; baptism began to shift from being primarily a response of faith to also being understood as a protective act. The center of gravity begins to move.
Once baptism started being applied to those who cannot yet believe, everything else connected to baptism was forced to adjust. The question is no longer only who should be baptized, but how, when, and why. The next developments flowed naturally from this unresolved tension.
The Shift in Modes of Baptism
Once the baptism of infants started, prisoners, elders, sick people, and those near death all stood in line to get this baptism with the goal in mind to reach heaven.
By the 3rd century, emergency or clinical baptism came onto the scene, where the ill or near-death people were baptized. Now most of these were confined to a limited space or a bed, so taking them out to rivers or other water sources was a difficult task. So the church started pouring and even applying water to these people. But many church leaders didn’t accept it as a valid type of baptism. But on the other hand, as it was possible to give baptism without fully immersing someone, some church leaders had mercy for infants, and they also changed methods for baptism of infants due to cold weather and even urban settings—where the running water or river was not present.
The change is not driven by doctrinal rebellion. It is driven by concern, speed, climate, space, and fear of delay. These are human pressures, and they leave fingerprints on religious practice. By the end of this period, the church still remembers immersion as the original form, but memory is beginning to compete with habit.
And habit, once established, is very hard to challenge without sounding like you are attacking the faith itself.
Theology of Infant Baptism
"It is human to err." The statement is correct, and I stand by it. Mostly due to Augustine's views on this infant baptism. We gave a new perception to baptism. He linked the idea of original sin to baptism. Which led people to get baptism at any cost and anyhow as well. This reframing changes how baptism was understood. It was no longer primarily the outward expression of an inward faith. It becomes a necessary remedy, a sacramental act that removes guilt and restores the soul. Once baptism was viewed this way, delaying it felt dangerous, even irresponsible. At the same time, the mode of baptism faded further into the background. If baptism works by divine action rather than human response, then the amount of water used becomes secondary. Immersion, pouring, or sprinkling can all be defended as sufficient, as long as the sacrament is administered correctly. So these theologians made infant baptism normal. Sprinkling and pouring efficiently and acceptably. Large baptisteries disappeared. What was once a public event becomes a brief ritual. Origen also claimed infant baptism was received from the apostles, but he provided no evidence, just confidence, which most theologians have by default. Church fathers did that sometimes. But on the other side of the front, the eastern guys stuck to full immersion only so the large baptisteries didn’t vanish. I would say that it was more a result of particular theological and cultural developments, not an unavoidable reading of Scripture.
Why do I disagree?
By the time these practices are firmly established, the lines are already drawn. Christians inherited different starting points, and those starting points shape how baptism is understood long before the water is poured, sprinkled, or entered. This is why the disagreement never truly disappeared, even when everyone claimed to be “biblical.” Biblically speaking, believer’s baptism has direct textual support, but infant baptism has no explicit command. That is the honest summary, even if it annoys people who prefer certainty wrapped in tradition or rebellion. Different traditions emphasize different things: Baptists / Evangelicals: baptism as a confession of personal faith & Catholic / Orthodox / Reformed: baptism as covenant inclusion and grace
Both sides are trying to be faithful. One side reads the text narrowly; the other reads the covenant broadly. The Bible itself leans toward faith-first baptism, but it also leaves enough silence for the church to argue responsibly & for me to write this paper.
