I cannot think of a single person in the New Testament who was ever baptized twice as a follower of
Jesus Christ.
Now, there were a few believers in Corinth who received a second water baptism, but
only because their first baptism had been a baptism of repentance preached by
John. This was insufficient; they needed to be baptized in the name of the Lord
Jesus.
But baptized twice as Christians? Never.* That in itself should strongly suggest it is impossible to
invalidate one’s baptism.
