Bethlehem Baptist Church’s long-standing practice has been to admit paedobaptists to membership. Here is John Piper’s response to Wayne Grudem’s change of mind:
I think in order to bar someone of the opposite position on baptism from membership with consistency, a church needs to adopt closed Communion. A Baptist church welcoming someone baptized as an infant to the Table as a guest but barring him from the Table if he decides to join the church is untenable.
