"Whereu, Jesus most definitely used God's personal name. (Matthew 4:10) Then Jesus said to him: “Go away, Satan! For it is written: ‘It is Jehovah your God you must worship, and it is to him alone you must render sacred service.’”"
MrGordon, I think that you probably know very well that it is not possible that Jesus would have used the name Jehovah. Although you don't disclose your source, here is how two well known versions translate Matthew 4:10.
Jehovah is not used, and for good reason; it could not have been because this rendition is not part of the languages of the time.
Matthew 4:10 New International Version (NIV) 10 Jesus said to him, “Away from me, Satan! For it is written: ‘Worship the Lord your God, and serve him only.
Matthew 4:10 King James Version (KJV) 10 Then saith Jesus unto him, Get thee hence, Satan: for it is written, Thou shalt worship the Lord thy God, and him only shalt thou serve.
"Would you also argue Jehovah did not use a name for his Son and certainly not Jesus which was a name invented well after the time of his ministry?"
So MrGordon, you argue on the basis that two wrongs make a right.
Anyway MrGordon, your Watchtower organisation has backed itself into a corner by choosing the name Jehovah's Witnesses where the name Jehovah can't be defended.
