Matthew 28:19 does say this in the King James Version (and the RNWT) "Matthew 28:19 in the King James Version reads: "Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:" RNWT: Go, therefore, and make disciples of people of all the nations, baptizing them in the name of the Father and of the Son and of the holy spirit.
A JW by means of this verse could say that it is implied that a JW baptism is being performed in the name of all three. Does it teach something different tho?
