This is fundamental, as shown by the commission of Christ, and is related to our faith in the Creator, Redeemer and Regenerator, and suggests the three steps in bringing men into the Divine image. But even if it was speaking of three persons, it does not say or imply that the Father, Son and Holy Spirit are three persons in one Supreme Being. But the scriptures do not give a personal name for the holy spirit. It is very evident, however, that the reference is not to mere words that are used to distinguish one person from another, but rather to the individuals themselves. I know your deeds, that you have a name that your are alive, but you are dead.
Name often means authority or power.
Thus David sent his men to Nabal in his name, that is, with his authority. These references all show that by coming in the name of another means to come with the authority given by that person. It does not necessarily refer to the word itself that is used to distinguish that person. This is My name forever, and this is My memorial-name to all generations. Therefore God has highly exalted Him, and bestowed on Him the name of which is above every name.
