A person never needs to be rebaptized. Baptism does not depend on the faithfulness of the ordained person doing the baptism, otherwise we would have to examine ourselves as well as the minister who is baptizing our child, as well as the elders overseeing it, as well as the local church before whose witness our child is being baptized. Our examination consists of believing God's promises and faithfulness. If we remain faithful throughout, then it is a fruit of Covenant membership, not a condition of it. If we fall, even to the point of having been excommunicated from the church, yet after many, many years, if we should repent we are received again into the body, as a prodigal son and not merely as a newly adopted son.

That is my understanding.
