“The Lord Jesus did in Matthew 28:18. “Universal” means applicable everywhere. On this passage the BDAG (3rd Edition) reads: Of Jesus’ total authority (exousia, page 353, the underlined is mine).”
“all authority” means that the son has the same/IDENTICAL commading authority as the father, meaning that the son has FULL access to the commanding powers that the father has?
let me tell you that if x has full access to a COMMANDING power, he does not need another to receive it, since the power is already in reach.
what does authority mean?
having authority over something does not mean having the power which gives you the power to command for something to be, to exist.
you are dangerously falling into polytheism and imagining things which the nt writers did not even image.
