Paedobaptism was practised in history. Here we remember the disagreement between St. Augustine and St. Jerome on the origin of the soul: whether is it born or created?. St. Augustine said that it is born with man and St. Jerome said that it is created. St. Augustine asked: "If it is created, it does not inherit Adam's sin. Why then do we baptise infants?" St. Jerome could not reply to this question.
