Apostolic Fathers
The
Didache has been a matter of discussion among Protestants on what it teaches about baptism. The Didache has been argued to have assumed believer's baptism, as it assumes discipleship before baptism and does not mention infant baptism. Against this,
Philip Schaff argued that the silence of the Didache about infant baptism "cannot be fairly used as an argument against it".
[15][16][17]
Similar to Tertullian later, the
Shepherd of Hermas implies for the practice of delaying baptism for the practical reason of the fear of post-baptismal sins, as Hermas says those who fall have only one chance of penance.
[18]
Polycarp stated, "I have served him eighty-six years and in no way has he dealt unjustly with me". Proponents of infant baptism argue that this quote shows Polycarp being
baptized as an infant, the argument being that if Polycarp was a servant of Christ for 86 years, he would have been a servant of Christ from infancy, suggesting infant baptism. However, against the argument, Schoedel William argued that the quote is ambiguous as regards to baptism, and that Polycarp meant by paraphrasing: "I have always served Jesus and I am not going to cease even at the age of 86."

Tertullian advised the postponement of baptism in the case of little children.
[20][21][22][23]
Infant baptism in this time was affirmed by
Hippolytus of Rome and
Cyprian, who announced the decision of the African synod to require the baptism of infants.
[24] The practice is also clearly practiced in the churches of Egypt very early, as seen from the writings of
Origen, who claimed it as apostolic tradition.
[25] However, according to Schreiner, Origen's need to make an apology for infant baptism implies it was not a universal belief.
[26] Tertullian (c. 198–203), in his treatise on baptism, advises the postponement of baptism in the case of little children, arguing that it is better to wait until one is ready to live what he professes in baptism rather than to repudiate the profession by wickedness. He however also advises to postpone the baptism of the unmarried, and mentions that the baptism of infants existed during his time, having sponsors speaking on their behalf.
[20][21][22][23]
Philip Schaff among many others have argued that
Justin Martyr affirmed infant baptism, Justin stating that some in his day have been disciples of Jesus since childhood, while
Dan Taylor instead claimed that Justin Martyr is "clear and full evidence" that infant baptism was not practiced during his time. He highlighted Justin's statements that one was "persuaded that the things spoken and taught by us are true", before baptism. Dan Taylor argued against the interpretation of the quote used to justify infant baptism, stating that by "discipleship", Justin was not referring to baptism but to teaching.
[27][25]
Thomas Schreiner argued that the
Apology of Aristedes indirectly excludes infant baptism, stating that the children of believers were considered part of the Christian community only after conversion.
[28]
Clement of Alexandria made no clear statements on infant baptism.
[29] Proponents of believer's baptism have argued that because Clement of Alexandria connects repentance and baptism, he supported the practice.
[30] On the other hand
Philip Schaff wrote that some statements that he makes can unclearly imply infant baptism.
[25]
Eusebius mentioned that an earlier presbyter who took a child and "committed to him, reared, kept, cherished, and finally baptized him".
[31]
In inscriptions from the end from the second century and later in which the date of baptism and death are mentioned, there is a close correlation between the time of baptism and their time of death. For example, Antonia Cyriaceti died and received baptism on the same day, Felite received baptism March 26 and died April 29. Multiple other inscriptions mention people of varying ages, who died as "neophytes" which implies someone whose baptism was a recent event, such as a Greek inscription that mentioned Achillia, who died in their 5th year as a neophyte.
[32]
The policy of the
Montanists discouraged baptism of infants.
[33] Additionally, some have argued that the schismatic
Novatians did not generally baptize infants, though the stance of the Novatians is disputed and by this point infant baptism had become clear among many orthodox writers.
