The direct evidence for infant baptism in the second and third centuries is sparse, and what exists points away from the practice. Tertullian — writing around 200 AD — explicitly recommended against baptizing children, arguing that delay allows personal readiness and avoids burdening sponsors with vows the child cannot yet fulfill. Other Fathers consistently tied baptism to illumination, repentance, and conscious ecclesial incorporation: Clement of Alexandria described it as progressive illumination leading to sonship and immortality; Hippolytus linked it to Christ's passion as a model for believers' renewal through understanding; Cyprian and Novatian debated the re-baptism of adult heretics without any reference to infants. The patristic evidence, taken together, portrays baptism as a deliberate, participatory act reserved for those capable of comprehension and commitment.
"The delay of baptism is preferable; principally, however, in the case of little children. For why is it necessary — that the sponsors likewise should be thrust into danger?" — the only explicit early discussion of infant baptism recommends against it, tying the rite to personal readiness and the ability to maintain baptismal commitment.
"Being baptized, we are illuminated; illuminated, we become sons; being made sons, we are made perfect; being made perfect, we are made immortal" — Clement's sequence of illumination leading to sonship and immortality presupposes cognitive engagement with the rite, consistent with the broader patristic pattern of baptism as a deliberate act of conscious faith.
