How Infant Baptism & Baptismal Regeneration Emerged
1st Century (New Testament Era)
Baptism is for repentant believers only—always follows personal faith (Acts 2:41; Acts 8:12, 36–38; Acts 18:8).
No examples or commands for infant baptism.
Baptism seen as a public profession and sign of union with Christ (Rom. 6:3–4), never as the cause of regeneration.
Late 1st – Early 2nd Century (Apostolic Fathers)
Didache (~A.D. 70–120): Earliest church manual—describes baptism for those taught and repentant, no mention of infants.
Justin Martyr (~A.D. 100–165): Describes baptism after catechesis (instruction) and confession of faith. No evidence of infants.
Mid–Late 2nd Century: Early Drift Begins
Irenaeus (~A.D. 130–200): Makes vague statements about Christ saving “infants,” later used by some to justify infant baptism—but no clear evidence he practiced it.
Tertullian (~A.D. 155–240): Explicitly opposes infant baptism, saying it should be delayed until a person can confess Christ—proving that the practice was beginning but was still controversial.
3rd Century: First Clear Cases of Infant Baptism
Origen (~A.D. 185–254): Claims infant baptism is “an apostolic tradition,” but gives no NT proof—reflecting an early appeal to “tradition” over Scripture.
Cyprian of Carthage (~A.D. 200–258): Oversees a council (~A.D. 253) that rules infants should be baptized even before the 8th day of life. The reasoning: baptism cleanses from “original sin.”
High infant mortality and fear of eternal damnation drive the urgency.
4th Century: The Rise of Baptismal Regeneration
Council of Nicaea (A.D. 325): Affirms baptism as the means by which sins are washed away, without distinguishing between infants and adults.
Constantine delays baptism until near death—revealing that baptism is seen as a one-time cleansing of sin.
Augustine (A.D. 354–430): Fully systematizes the doctrine—teaches that all are born guilty (original sin) and that unbaptized infants are condemned; baptism is necessary for salvation.
This cements the belief that baptism itself regenerates.
5th–6th Century: Institutionalization
Baptism of infants becomes the norm across the Roman Empire.
Catechesis (training in the faith) now occurs after baptism, reversing the NT order.
Baptism is taught as the moment of regeneration—confusion between the sign and the thing signified becomes embedded in church life.
Medieval Period (7th–15th Century)
Roman Catholic Sacramental System fully integrates baptismal regeneration.
Baptism believed to remove both guilt and punishment of original sin, granting grace ex opere operato (“by the work worked”)—regardless of personal faith.
Reformation (16th Century)
Reformers reject baptismal regeneration in the Roman Catholic sense, but Lutherans and Reformed paedobaptists retain infant baptism—seeing it as a sign of the covenant rather than a cause of regeneration.
Anabaptists and later Baptists return to believers-only baptism based solely on NT precedent.
Summary Flow
NT Era: Faith → Baptism (only for believers).
2nd Century: Pastoral concern for infants + creeping sacramentalism.
3rd Century: Official acceptance of infant baptism for “remission of sins.”
4th Century: Baptismal regeneration formalized—salvation tied to the act.
5th Century onward: Institutionalized tradition overrides apostolic teaching.
Key Takeaway:
Infant baptism began as an unscriptural tradition fueled by high infant mortality, fear of damnation, and sacramental misunderstanding. Baptismal regeneration was the theological cement that locked it in place—both foreign to the New Testament gospel of salvation by grace alone through faith alone in Christ alone.
Baptism: From Apostolic Truth to Man-Made Tradition

New Testament Teaching
Early Church Drift
Full False Doctrine
Candidates for Baptism
Only those who personally repent and believe in Christ (Acts 2:38, 41; Acts 8:12, 36–38; Acts 18:8).
Parents begin requesting baptism for dying infants—seen as a special exception, not the rule.
Every infant of Christian parents baptized as a matter of course—faith not required.
Purpose of Baptism
Public sign of union with Christ, identifying with His death, burial, and resurrection (Rom. 6:3–4; Col. 2:12).
Starts being viewed as the moment when sins are washed away—especially for infants.
Regarded as the means of regeneration and removal of original sin (ex opere operato—“by the work worked”).
Timing
After hearing the gospel and responding in faith (Acts 2:41; Acts 16:31–33).
Infant baptism allowed when a child is near death—justified as “washing away original sin.”
Baptism performed as soon after birth as possible to secure the infant’s soul.
Basis for Practice
Direct apostolic command and example (Matt. 28:19–20; Acts 8:36–38).
Appeal to “apostolic tradition” without biblical proof (Origen, 3rd century).
Church councils and theological systems override Scripture (Cyprian, Augustine).
Relation to Salvation
Baptism follows salvation—it’s the outward sign of inward faith (Eph. 2:8–9; Titus 3:5).
Some begin to see baptism as instrumental in salvation.
Baptism is declared necessary for salvation—unbaptized infants presumed lost.
Catechesis (Teaching)
Catechesis precedes baptism—hear the gospel, believe, be baptized (Acts 2:41; Acts 8:12).
In some places, catechesis begins after baptism for infants.
Catechesis almost entirely post-baptism; baptism assumed to place one “in Christ” automatically.
