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?
Maybe we are just splitting hairs here. He gave them the great commission, and yes, He gave them the authority to carry it out. I was just reacting to the exact words you used, that’s all. Enjoy life. I do.
That applies to ALL believers, not just a certain select, elite, self-appointed group.
