Yet another thread devolves, this one into pointless etymologies. DavidJ seems to have some sort of axe to grind in regards the Catholic Church. This whole thread is yet another re-hash of an old, trite arguement against the papacy. Yawn.
Not that anyone really cares, but the office of bishop (episkopos) is mentioned in the Bible. Bishops are mentioned in Acts 1:20, 20:28; Phil 1:1; 1 Tim 3:1-2; Titus 1:7; and 1 Peter 2:25. The Pope is the Bishop of Rome. Very Biblical. Also, Ephesians 4:11 does mention the pope. That would be the phrase "pastor and teacher". As does 1 Corinthians 12:28 in the words "third teachers". The Pope is foremost a teacher. He is also the pastor of a local church in Rome. Very Biblical. If you have a problem with the word "Pope", take it up with the Coptic Church as they originated the term and still use it today to describe the Coptic Bishop.
Peter was the first Bishop of Rome. History verifies that. It doesn't matter one iota whether that fact is recorded in the Bible or not. The Bible also does not record the first Bishop of Byzantium nor the first Bishop of Damascus. So what? We know who they were through historical sources. Paul is not the gold standard.
The Bible also does not fail to mention the office held by the Pope. As pointed out, Matthew 16:17-19 clearly shows that Christ reinstated the ancient Davidic office of chamberlain. While arguing about rocks, petras, and kephas, Christ's citation of Isaiah 22:22 has been completely ignored as has Simon's name having been changed to Peter by God in the person of Christ. Why does God change Simon's name to Peter and what does it signify? Why only Simon among the 12 Apostles? Why does Jesus quote Isaiah 22:22 in regards to Peter and the Church?
Regarding Matthew 16:17-19, its not just Catholics that acknowledge Christ establishing His Church with Peter as its head, but also many well-known and respected Protestant Bible scholars acknowledge this fact as well. You might read this paper which quotes a number of these scholars:

Catholics fully agree with all the scriptures cited. Jesus has all authority over heaven and earth; however, Peter and his successors have the authority Jesus delegated to Peter via the keys, and, as the key holder, may, in fact, issue religious "laws". Isaiah 22 and Matthew 16 say so. None of that dimishes our Lord's authority one iota. Get over it.
Regarding "papal infallible hypocracy", one might learn what the doctrine of infallibility is before one tries to argue against it. You made a great arguement against impeccability, but not infallibility. Catholics agree with you, the Pope is not impeccable. Common ground at last.
God bless...
