Even if God were a trinity, Jesus is the one who died for us and He is the one who the Christians at Rome were buried with . For as many of you as were baptized into Christ have put on Christ. As I said before, the only way that we see anyone being baptized is in Jesus' name. He was Jesus. But when we stand in his stead, we do it in his name.
Baptism is an act of both word and deed.
Finally, I would like to demonstrate where history shows us that the Catholic Church changed the way that people were baptized. The early church always baptized in the name of the Lord Jesus until development of the Trinity Doctrine in the Second Century. Here the Catholics acknowledged that baptism was changed by the Catholic Church. Vol. 2, pg. Baptism was always in the name of Lord Jesus until time of Justin Martyr when Triune formula used.
