“Again Eisegesis !”
The words of the Apostles and Prophets directly contradict you. The LORD wouldn’t say to our Lord “sit thou at my right hand, till all enemies be made your footstool” unless there really was a difference. There would be no need to baptize in the name of the Father, Son and Holy Spirit if all were just different names for ONE person. Nor would there be any reason for Christ to pray... to Himself (the Father), during His earthly ministry, unless He, being fully God and fully man, had temporarily chosen to not move according to His own will to live the perfect human life.
"Go ye therefore, and teach all nations, Go, and make disciples of all the nations in My Name, teaching them to observe all things whatsoever I have commanded you,” [[Matt. xxviii. 19.]] From Proof of the Gospel (the Demonstratio) by Eusebius.
