This paper inquires into the situation of small children during the Hellenistic-Roman era, including NT texts and later Christian writings in the first two or three centuries. There was an early form of ‘Christian education’, and probably, children of baptized parents belonged to the Christian communities. In 1 Cor 7.14, Paul indirectly argues in favour of a ‘Christian influence’ on the ‘holy children’ by the ‘believing’ father or mother. In Eph 6.4, the author, speaking about παιδϵία καὶ νουθϵσία κυρίου, argues that in a Christian household children should have instruction in the Christian faith. The question of the baptism of small children might be answered by the interpretation of 1 Cor 1.14–16, where Paul precisely distinguishes between baptism of individuals (1.14) and baptism of the ‘house of Stephanas’. Mark 10.13–16 is a mirror of a discussion between those who ‘rebuke’ people for bringing children to Jesus, and Jesus himself who interprets their action as a ‘prevention’, thus escalating the conflict to a fundamental one, which probably refers to the question of baptism of children. During the last century, we have learned (again?) to see childhood not only as a transitional period of human life but one to be protected by society. Possibly similar ideas existed during the times when our texts were written.
