In some churches which do not baptize infants (such as the Baptists ), a practice has developed by which the baby and parents have a ceremony in the church in which the child is consecrated to God with some language to that effect. It is similar in appearance to a baptism except, obviously, no actual baptizing. I dont know when it originated.
Well, there certainly is, and we read posts here all the time talking about it. It is not a specific age like 6 or 15 or anything firm, but if those churches that say that an infant cannot be baptized because the child cannot comprehend enough to make a personal commitment to Christ, they make a mockery of their own theory when they turn around and baptize 8 or 9 year olds--which many, if not all, of those churches do--because no kid of that age comprehends faith, grace, morals, etc. like an adult can. For them, it is a matter of saying the words and knowing that Jesus loves us, etc. but nothing that would qualify as a conversion experience.
