Thanks for your question.
There is no set formula for baptism. One possibility is that given in Matthew 28:19. In the Acts of the Apostles, people were typically baptized into the "Name of the Lord Jesus Christ."
There is no set formula to be used at a baptism. When I baptize someone, I typically say, "I baptize you in the name of the Lord Jesus Christ for the forgiveness of your sins and entry into the household of God."
I hope you have found this helpful.
