Direct Answer
In the supplied evidence, the early Christian writers believed that Christian baptism was normally water baptism given to believers—people brought to repentance, faith in Christ, and the name of Christ—and that in this baptism “the remission of sins is received.” They did not use the later modern label “believer’s baptism,” but they did use language that closely fits it: “the first baptism to believers,” “those who are made lawful believers,” and those “who believe in the Lord Jesus Christ.”
At the same time, the evidence here is limited. The retrieved early Christian texts do not give a full treatise on every baptismal question, and they do not supply a direct discussion of infant baptism. What they do show is that at least these Ante-Nicene witnesses understood baptism as connected with hearing the gospel, repentance, faith, water, the name of Christ, remission of sins, and the gift of the Holy Spirit. They also recognized an extraordinary “baptism of blood” in martyrdom, but they did not use that exception to make water baptism optional when it was available.
What Scripture Says
There are no separate Scripture-source rows in the retrieved material, but the early Christian texts themselves quote and apply several biblical passages. Since Scripture is the first authority, those quoted passages are the best place to begin.
John’s baptism prepared for Christ’s baptism
The anonymous Ante-Nicene Treatise on Re-Baptism begins its discussion of Christian baptism by looking back to John the Baptist. It says that John “prepared the way for the new and true grace” and that he did so “by the baptism of water and of repentance.” Then it quotes John’s announcement about Christ:
“He that comes after me is mightier than I, whose shoe’s latchet I am not worthy to unloose: He shall baptize you with the Holy Ghost, and with fire” (Matthew 3:11).
The treatise draws a contrast between John’s preparatory baptism and the fuller baptismal reality brought by Christ. John’s baptism is described as a baptism “of water and of repentance,” preparing hearers for the coming spiritual baptism. That matters for believer’s baptism because the passage begins with repentance and reception of the message. The people being prepared are not described as passive members of a covenant community apart from response; they are being called to repentance and to listen for the coming Christ.
The treatise continues by connecting John’s words with the risen Lord’s words in Acts:
“John truly baptized with water, but you shall be baptized with the Holy Ghost not many days from now” (Acts 1:4-5).
The point is not that water is unimportant. The same treatise continues to discuss Christian water baptism. But the passage shows that early Christian reflection on baptism did not separate water from the work of God. Baptism was not treated merely as a human rite; it was considered in relation to repentance, the promise of the Father, and the Holy Spirit.
Peter’s explanation: hearing the gospel, believing in Christ, and receiving the Spirit
The same treatise also quotes Peter’s explanation after the Holy Spirit fell on Gentiles:
“And as I began to speak, the Holy Ghost fell upon them as on us at the beginning; and I remembered the word of the Lord, how that He said, John indeed baptized with water, but you shall be baptized with the Holy Ghost. If, therefore, He gave them a like gift as to us, who believe in the Lord Jesus Christ, who was I, that I could withstand the Lord?” (Acts 11:15-17).
Here the crucial phrase for the question is “who believe in the Lord Jesus Christ.” The treatise uses Peter’s words while discussing “saving and new baptism,” “spiritual and evangelical baptism.” The biblical pattern cited is not detached from faith. The Gentiles hear the gospel, God gives the Spirit, and Peter identifies the people involved as those who “believe in the Lord Jesus Christ.”
The treatise then begins another quotation from Peter:
“Men, brothers, you know how from ancient days God made choice among us, that the Gentiles by my mouth should hear the word of the Gos...”
The supplied excerpt cuts off there, but even the portion given stresses that the Gentiles were to “hear the word” by Peter’s mouth. Again, the baptismal discussion is framed by proclamation, hearing, and believing.
So, from the Scripture quoted in the early Christian source, the pattern being appealed to is this: John calls people to repentance and water baptism; Christ promises the Holy Spirit; Peter sees Gentiles hear the gospel, believe in the Lord Jesus Christ, and receive the Spirit. The supplied material does not include a full biblical study of baptism, but the Scripture it does quote is consistent with baptism belonging to repentant believers.
What the Early Christian Writers Say
1. The Treatise on Re-Baptism: “saving and new baptism” begins with repentance and the Spirit
The Treatise on Re-Baptism opens its argument this way:
“Therefore, for those who begin a discussion of saving and new baptism, that is, spiritual and evangelical baptism, the first thing that comes before them is the announcement that is known everywhere, made and begun by John the Baptist.”
It then says that John:
“prepared the way for the new and true grace. By the baptism of water and of repentance, which he practiced for a time, he gradually prepared the Jews to listen.”
This is important because the treatise does not describe baptism as an isolated ritual. It calls Christian baptism “saving and new,” “spiritual and evangelical,” and it explains John’s water baptism as a baptism of repentance that prepared people “to listen.” In this early Christian discussion, baptism belongs in the setting of the preached word, repentance, and the coming grace of Christ.
The treatise then quotes Matthew 3:11, Acts 1:4-5, and Acts 11:15-17 to show that John’s baptism pointed beyond itself to Christ’s baptism with the Holy Spirit. It speaks of those in Acts as people “who believe in the Lord Jesus Christ.”
This does not yet answer every later baptismal controversy, but it does show the basic orientation of the author’s thought: baptism is evangelical, connected with repentance, hearing, believing, and the work of the Spirit.
2. The Treatise on Re-Baptism: “lawful believers” are baptized “in the name of Christ”
Later in the same treatise, the writer discusses water baptism, martyrdom, and salvation. He says:
“Thus certain ways of the one baptism were opened to us, so that at times one of them might be lacking without harm. This is as in the case of martyrs who hear the word: the baptism of water is lacking without evil. And yet we are certain that these, if they had any opportunity, would also have been baptized with water.”
This passage is very revealing. The author recognizes an exceptional case: martyrs who “hear the word” may die before receiving water baptism. In that case, he says water baptism is “lacking without evil.” But he immediately adds that such martyrs, “if they had any opportunity, would also have been baptized with water.”
That tells us two things. First, water baptism was expected. Second, the exception does not erase the expectation. The ordinary Christian path is not hearing the word and then neglecting baptism. The martyrs are excused because they lack opportunity, not because baptism is unnecessary.
The treatise then speaks of another group:
“And also for those who are made lawful believers, the baptism of their own blood is lacking without harm, because, being baptized in the name of Christ, they have bee...”
The excerpt cuts off after “have bee...,” but the relevant phrases are clear. These people are “made lawful believers” and are “baptized in the name of Christ.” The author’s categories are believers and baptism in Christ’s name. He is not merely speaking of a social ceremony; he is speaking of people who have become believers and have received Christian baptism.
3. Treatises, Treatise 11: “the first baptism to believers” and “remission of sins”
Another Ante-Nicene passage, titled Treatises - Treatise 11, gives one of the clearest statements in the retrieved sources. While exhorting Christians to martyrdom, the writer says:
“Let us, who by the Lord’s permission have given the first baptism to believers, also prepare each one for the second...”
That phrase is direct: “the first baptism to believers.” The writer distinguishes the ordinary baptism already given to believers from the “second” baptism of martyrdom. He then explains the difference:
“In the baptism of water, the remission of sins is received; in the baptism of blood, the crown of virtues.”
This is one of the strongest pieces of evidence in the supplied material. It explicitly says that the church’s ministers had “given the first baptism to believers.” It identifies that first baptism as “the baptism of water.” It also says that in water baptism “the remission of sins is received.”
This shows that, in this source, believer’s baptism was not treated as a bare symbol only. It was water baptism administered to believers and associated with receiving remission of sins. The writer’s concern is not to minimize baptism but to encourage those already baptized in water to be faithful even to death. Martyrdom is described as another baptism, “greater in grace” and “higher in power,” but it is built on the assumption that the first baptism has already been given to believers.
The same passage says the baptism of blood is:
“a baptism after which no one sins anymore—a baptism that completes the growth of our faith—a baptism that, as we depart from the world, immediately joins us to God.”
So the author sees martyrdom as a final consummation of faith. But the ordinary beginning remains “the first baptism to believers,” the water baptism in which “remission of sins is received.”
4. Tertullian’s To His Wife: believers as the normal Christian household category
One supplied source, To His Wife - Book II: Chapter 8, is not primarily about baptism. It speaks about marriage between Christians and describes the blessedness of “two believers” sharing Christian life:
“What a yoke that is, of two believers sharing one hope, one desire, one discipline, and one and the same service. Both are brothers, both fellow servants.”
This passage should not be used to prove baptism directly. It does, however, show the early Christian habit of identifying Christians as “believers” who share one hope, discipline, service, prayer, fasting, the church, and the “banquet of God.” In the baptismal sources above, baptism is likewise spoken of as given to “believers.” The Tertullian passage is supporting background at most, not a main baptism text.
What Is Explicitly Stated
Several things are explicitly stated in the retrieved sources.
First, John’s baptism is described as “the baptism of water and of repentance.” The Treatise on Re-Baptism says John used this baptism to prepare the Jews to listen and to announce the coming baptism of the Holy Spirit and fire.
Second, the same treatise explicitly identifies the people in Acts 11 as those “who believe in the Lord Jesus Christ,” quoting Peter’s words. This places the discussion of baptism in the setting of faith in Christ.
Third, the treatise explicitly says that martyrs who heard the word but lacked water baptism would have received it if they had opportunity:
“And yet we are certain that these, if they had any opportunity, would also have been baptized with water.”
This is a strong statement that water baptism was normally expected of those who heard the word and followed Christ.
Fourth, the treatise explicitly speaks of “those who are made lawful believers” as “baptized in the name of Christ.” That phrase directly connects becoming believers with baptism in Christ’s name.
Fifth, Treatises - Treatise 11 explicitly says:
“we ... have given the first baptism to believers”
and then identifies that first baptism as water baptism:
“In the baptism of water, the remission of sins is received.”
So, if the question is whether the early Christian sources here support baptism of believers, the direct answer is yes. They explicitly speak of baptism being given to believers.
What Is Strongly Implied
The sources strongly imply that baptism was ordinarily administered after a person had heard the word, repented, and believed in Christ. The implication comes from the way the baptismal discussion is framed: John calls people to repentance; Christ promises the Spirit; Peter describes those who receive the divine gift as those who “believe in the Lord Jesus Christ”; martyrs are described as those who “hear the word”; and Christian water baptism is called “the first baptism to believers.”
The sources also strongly imply that water baptism was not treated as optional for believers. The clearest line is the one about martyrs. The author allows that water baptism may be “lacking without evil” for martyrs who had no opportunity, but he adds:
“if they had any opportunity, [they] would also have been baptized with water.”
That is not the language of a merely optional rite. It is the language of a normal Christian obligation, with an exception only where opportunity is absent.
The sources also imply that baptism was understood as more than a public testimony. Treatises - Treatise 11 says:
“In the baptism of water, the remission of sins is received.”
Whatever further theological distinctions one might make, the supplied source itself connects water baptism with the reception of remission of sins. Therefore, it would be inaccurate to summarize these texts as teaching only that baptism outwardly symbolizes a salvation already complete in every respect. The author’s own wording gives baptism a real place in receiving remission.
Finally, the sources strongly imply that the early writers distinguished ordinary Christian baptism from extraordinary martyrdom. They speak of “one baptism” in certain “ways,” of water baptism, and of “baptism of blood.” But the baptism of blood is not used to replace water baptism for ordinary believers. It is an exceptional gift in persecution, especially where water baptism was unavailable or where the baptized believer is later called to die for Christ.
What These Sources Do Not Address
These sources do not give a complete history of baptism in the whole early church. The retrieved material is narrow: mainly the Treatise on Re-Baptism, one passage from Treatises - Treatise 11, and a non-baptismal passage from To His Wife.
They do not supply a direct quotation from the Didache, Justin Martyr, Irenaeus, Tertullian’s baptismal treatise, Origen, or other well-known early Christian discussions of baptism. Therefore, this answer should not pretend to represent every early Christian writer or every regional practice.
They also do not directly discuss infant baptism. The evidence here supports baptism being given to believers, but it does not contain a direct early Christian argument either for or against baptizing infants. A careful answer should not claim more than the supplied texts say.
They do not define the exact mode of baptism, such as immersion, pouring, or sprinkling. The excerpts speak of “water,” “baptism of water,” and being “baptized in the name of Christ,” but they do not describe the physical method.
They do not provide a full doctrinal explanation of how baptism relates to faith, grace, forgiveness, and the Holy Spirit. They do say that water baptism is given to believers and that “remission of sins is received” in it. They also quote Scripture about Christ baptizing with the Holy Spirit. But they do not answer every later theological question about sacramental causality, regeneration, or the precise timing of forgiveness.
Summary
The supplied early Christian evidence supports a careful answer: early Christians in these sources treated baptism as water baptism given to believers. They connected it with repentance, hearing the word, faith in Jesus Christ, being baptized in the name of Christ, the Holy Spirit, and remission of sins.
The strongest direct statement is from Treatises - Treatise 11:
“we ... have given the first baptism to believers”
and:
“In the baptism of water, the remission of sins is received.”
The Treatise on Re-Baptism likewise speaks of “those who are made lawful believers” as “baptized in the name of Christ,” and says that martyrs who heard the word but lacked water baptism would have received it if they had opportunity.
So, on the evidence supplied, the early church did believe in baptism for believers. But the answer should be stated with precision: these texts show that believer baptism was explicitly taught and assumed in these early Christian sources; they do not, by themselves, settle every historical question about all early Christian baptismal practice.
