Umm… so, wait a minute…
When Jesus told the apostles (in Matthew 28:19), “Go, therefore, and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the holy Spirit”,
Jesus got it wrong, but when (in Acts 2:38), Peter says, “Repent and be baptized, every one of you, in the name of Jesus Christ for the forgiveness of your sins”,
Peter got it right?
As a Bible-believing Christian, she’s really saying that she takes Peter’s words over Jesus’s? (You’d think that’s what she might accuse us Catholics of doing…

)
In any case, Peter is preaching
Jesus to the crowds. So, naturally, he wants to emphasize that the baptism he’s talking about isn’t the baptism of John, or any of the ritual washings of the Jews or Essenes, or any of the Greek pagan (mystery cult) rituals. Rather, this is a baptism in Jesus’s name (which, if we recall from Matthew 28:19, from the mouth of Jesus himself, is a baptism in a Tridentine formula).
