Again, the bible itself says that a concept is established/confirmed by 2 to 3 witnesses.None of this undoes the command of Jesus, the name you are claiming is the single name.
Matthew 28:19
Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit,
We are told that the bible does not contradict itself. Therefore it is obvious that Jesus meant that His name was to be used in water baptizing. Otherwise there would be occurrences in the bible where people were water baptized using the formula of "the Father, and of the Son, and of the Holy Ghost. They do not exist.
Take the time to search out water baptism, water baptized, etc. And you will see the truth.
