Jesus never taught that the “triune” is the true God.
That is a fabrication of the Nicene Creed in 325.
Do you mind explaining then, Tep, why Jesus said to baptize in the singular NAME of the Father, Son, and Holy Ghost???
19 Go ye therefore, and teach all nations, baptizing them in the NAME of the Father, and of the Son, and of the Holy Ghost: (Matthew 28:19)
Why didn't Jesus use the plural "Names" if plurality was His main focus?
