I have never heard a Catholic refute the end of John, where Peter says “Lord, what about this man?” and Jesus basically responds that he is no concern of Peter’s. Excuse me, Simon’s. Peter was supposed to follow Jesus, NOT shepherd the other disciples.
Your concern over Peter’s name change is baffling. Before he met Jesus, Simon was Simon. Jesus gave him a new nickname, and it stuck, though people continued to call him Simon Peter or Cephas or simply Simon. This is a stretch, and you’re not establishing much credibility with this silly argument.
Now, regarding John 21, I’ll “refute” your position now.
20 Peter turned and saw that the disciple whom Jesus loved was following them. (This was the one who had leaned back against Jesus at the supper and had said, “Lord, who is going to betray you?”) 21 When Peter saw him, he asked, “Lord, what about him?”
22 Jesus answered, “If I want him to remain alive until I return, what is that to you? You must follow me.” 23 Because of this, the rumor spread among the believers that this disciple would not die. But Jesus did not say that he would not die; he only said, “If I want him to remain alive until I return, what is that to you?”
24 This is the disciple who testifies to these things and who wrote them down. We know that his testimony is true.
Jesus has just told Peter that He would be martyred, so when Peter turned and saw John following them, Peter was naturally curious as to John’s fate, also. Jesus said, “If I want him to remain alive (instead of dying as a martyr), that is none of your concern.”
The death of a man is not within the realm of shepherding; it is up to God and God alone to decide when and how a man will die. Why would you think otherwise?
I’ll leave it to you to find the passage in Acts where the church SENDS Peter. Not Peter, in charge of the church, goes, but is SENT. Not a papal mission but in submission to the church. I could go on but I have to get off.
Big whoop. The Church felt that the need required Peter’s presence because of his stature as the head of the Church, so it was agreed that Peter would go.
Are you suggesting that if a group of Cardinals today implored the Pope to make a trip to a specific country, he wouldn’t go because it wasn’t his idea?
And if he did go, would that be a case of “the Church”
sending him on an important diplomatic or missionary mission?
