Fortunately he did not say that. Acts 2 is quite clear. No trinitarian formula in there. The Church missed forging it.<quoted text>
St Peter was only talking about by whose authority one is baptized and not giving the fomula for baptism. He could say: "By the authority of Jesus Name, I baptize you:-In the Name of Father, Son and Holy Spirit.'"
Keep on spinning, Paul! That is what the lying Church did.
