If you are referring to Mattew 28:19-19, then naturally I disagree with your interpretation. He said all authority was given to HIM, not to the disciples. He merely told them what to do. Did He give them power to carry out His will? Of course, but the authority was given to HIM.
You’re right. The authority was gigven to him and he passes it on to the Apostles when he says, “I will be with you always.”
For me, it’s reading another level into the reading. What else could it mean?
In another place he tells them not to worry about what words to say, for when the time comes, the Holy Spirit (also God) will give them the words.
Didn’t Christ ask the apostles to wait in Jerusalem for the coming of the Advocate and the passing on of his power and authority?
