In what you quoted from the two posts, I don't see anything to indicate the Holy Spirit is the "representative" of Jesus. Maybe I don't understand what you mean by "representative" of Jesus. Could it be our definitions/understandings simply differ?
"...Whom the Father shall send in My name..."
An ambassador is sent "in the name of" the one he represents - likewise, the Holy Spirit is sent "in the name of" Him Whom He represents: Jesus.
Moreover,
anyone filled with the Holy Spirit, too, is an "ambassador" for Christ, such as Paul when he spoke of being "in the person of Christ".
If a pope is filled with the Holy Spirit (which I highly doubt) then, yes, he too is a "representative" of Christ,
but no more a representative of Christ than the Christian janitor who cleans the lavatory in a small country church in some obscure valley or hollow.
When Catholics consider Peter as being "the rock" of the church, they consider the following:
I'm going point by point to ensure we don't speed past this:
- In all four Gospels, the Apostles are listed four times. Peter is named first in every occurrence.
In Matthew and Mark, Peter and Andrew are mentioned respectively. Both are called to follow
simultaneously.
In Luke, Peter is mentioned first, but - again - Jesus calls several to follow
simultaneously.
In John,
Andrew and another unnamed disciple are mentioned first, calling Jesus "rabbi" and later "Messiah". These two "followers" of Jesus had spent at least 2 hours with Jesus - and possibly all night - before Andrew had to find and drag his brother Peter to meet Jesus.
Claiming this makes Peter special is purely subjective reasoning - wholly inadequate to make Peter a "pope".
- Peter was chosen by the Father to receive the revelation that Jesus is "The Messiah."
The revelation was given
first to Andrew and his companion when they left the Jordan with Jesus -
not Peter.
They first called Him "rabbi" but after spending time with Him - and presumably being shown the prophecies of the
Book of Daniel where "Messiah" is found exclusively - Andrew and his companion knew He was "Messiah".
- Peter is listed separately as a witness to the Resurrection before the other Apostles.
Peter didn't witness any Resurrection, merely an empty tomb, which was first found by women. Should we ordain women popes?
- Peter was charged by Christ to "strengthen your brothers and to "feed my sheep."
Acts 20:28 KJV says elders are to do the exact same thing. I served as elder - does that make me a "pope"?
- Peter presided over the election of Matthias to replace Judas, also listing the requirements for candidacy.
How does this make Peter "the first pope" especially when we know he later submitted to Paul's authority?
- Peter was the first to preach the Gospel on the day of Pentecost.
Paul hadn't joined yet, else he would have surely preached. The man wrote almost the entire NT.
- It was Peter who defended the other Apostles before the Sanhedrin in Acts.
Stephen defended Christ and the church at large and was stoned to death - should he be promoted as "pope"?
- Peter exercised his authority to discipline Ananias, Sapphira and Simon the magician in Acts.
And Paul exercised his authority over Peter when Peter was guilty of racial injustice. So much for Peter's "infallible papacy", right?
- It was Peter who received a vision of the Lord to inspire the Jewish Christians to allow Gentiles into the Church.
Paul received countless visions from God - but because of Peter's racial prejudice, God elected to give him that vision to "
show me that I should call any MAN common or unclean".
And of course, there's Matthew 16:18-19: "And I tell you, you are Peter, and on this rock I will build my church, and the powers of death shall not prevail against it. I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven." (emphasis added by me)
Seems pretty compelling to me, that even if Peter was a bit of a 'screw-up', Jesus saw something in him...
I'm just thinking out loud here, but...
...maybe Jesus chose Peter because Peter was a 'screw-up.' Hmmm...
Can't tell you how much that I really like this! Did you make this up, or get it from somewhere else?
Only if we ignore the original Greek - yes, it seems "Jesus must have seen
something in Peter and built the church upon him".
However, in the Greek, Jesus calls Peter "Petros" which is a "small stone of instability" but then says He's going to build His church on this "Petra" which is a "giant rock of immense proportion".
How can "Petros" be "this Petra"? It's like saying "I've got a 12" black and white and upon this big screen IMAX monolith I'm watching the Superbowl".
Peter's
confession is the "Petra" to which Jesus was referring and upon which His church is built.
