I have never encountered the assertion that paraclete andvicar were remotely similar in meaning.
And in any event that is a red herring. You implied that to have a Pope as head was to displace Christ. So now are you dropping thatc or are you just changing the subject?
Nope, I say that there is no need for a “representative” other then who Christ says He sent and that is the Holy Spirit. The Holy Spirit trumps the Pope and we have the Holy Spirit. The Pope trying to usurp the position of the Holy Spirit is an abomination.
