Acts 3:6 Then Peter said, Silver and gold have I none; but such as I have give I thee:In the name of Jesus Christ of Nazareth rise up and walk.. 7 And he took him by the right hand, and lifted him up:and immediately his feet and ankle bones received strength.
If originalist is trying to say that the name can be used without the authority I agree. For instance if someone is baptized in the name Jesus Ramirez, that isn't the Jesus we need for salvation. If he is saying that we are given authority without the name that is contrary to the Bible. Peter had more supernatural experience through God than anyone on this earth today, but yet he still vocalized Jesus name here in the scripture.
I think that originalist probably sees the importance of the name. It seems he is trying give a deeper philosophy then is necessary. We should call on his name everyday, but it is up to God where his authority is used. If we don't acknowledge his name we disgrace his person. Have you ever been referred to in a group acquaintances as a he or him when they know your name? To me if it is done repeatedly it is insulting. I have name for a reason so use it when you refer to me.
By using His name when you speak of Him you acknowledge Him. By calling on His name in baptism you are being obedient. Originalist would probably be getting less debate if he would have said the use of the name is in vain if we truly don't know Him and don't experience His work in our lives.The name is important because of who it belongs to.
