In order to avoid replowing the ground...define “person” above, and then perhaps I can move on the the rest of your question.
Well, in the verses from Matthew, Galatians and 2 Cor. that we have seen, “person” is someone who can be or not be respected, can pray, or give and receive authority to others to act on his behalf. Neither of these abilities pertain to a presence but they pertain to a person.
