I know the sons of a Presbyterian minister who were not baptized until their mid-teens.
Infant baptism is a basic principle of the Reformed faith. It's not something that's debated. But it's not a means of "soul-saving" to the Presbyterian, as it is to the Catholic or Evangelical.
FWIW, our sons were baptised in our Presbyterian church as pre-teens, not infants. This was only due to the fact that we finally found a church we liked and wanted to be a part of.
But Reformed means infant baptism.
It would be interesting to know what branch of the presbyterian tree that Pastor is. Presbyterians have a covenant theology so a teen baptism make no sense from that perspective, Most non Calvinist and reformed Baptists teach a believers baptism .also a sign sacrament (dying and being born again)
