In the final three verses of Matthew, all translations read much like that of the ESV as follows:
And Jesus came and said to them, “All authority in heaven and on earth has been given to me. 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, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.”
If this is what Jesus said, why is it that his disciples did not obey? In each of the four instances recorded in the book of Acts, people were baptized or instructed to be baptized in the name of Jesus only:
Acts 2:38 And Peter said to them, “Repent and be baptized every one of you in the name of Jesus Christ for the forgiveness [or “forsaking”] of your sins, and you will receive the gift of the Holy Spirit.
Acts 8:16 for he had not yet fallen on any of them, but they had only been baptized in the name of the Lord Jesus.
Acts 10:48 And he commanded them to be baptized in the name of Jesus Christ. Then they asked him to remain for some days.
Acts 19:5 On hearing this, they were baptized in the name of the Lord Jesus.
I wanted to look up the final verses of Matthew in the existing manuscripts that were copied prior to A.D. 300, but unfortunately no extant manuscript from before A.D. 300, contains the words. A unitarian site suggests that Matthew may have actually written, “Go therefore and make disciples of all nations, baptizing them in my name”—especially since “name” is in the singular, indicating just one name. They suggest that Trinitarians later changed “my name” to “the name of the Father and of the Son and of the Holy Spirit.” What are your thoughts on the matter?
