I can’t speak of all Protestants, but I certainly believe in the laying on of hands. Pentecostal ministers lay hands on those being ordained. But I think the important difference is apostolic succession. We don’t believe in it. The calling of someone to minister is very much an act of the Holy Spirit. However, whether the church recognizes that act through ordaining and setting them apart for service does not negate the original call of God on their life.
“Apostolic succession” DOES NOT mean that the Pope, or any other bishop, succeeds to the full office of an Apostle. That is not the Catholic claim at all. Rather, “Apostolic succession” maintains that a Pope, or a particular bishop, succeeds
FROM an Apostle or Apostles.
It, in no way, implies that this Pope or this bishop is now an Apostle himself.
Furthermore, it in no way implies that this Pope or this bishop is Divinely-inspired (as the Apostles were), or infallible (in the sense that the Apostles were), or that they are the originators of new, Christ-given revelation (as the Apostles were). Rather, the Pope and his brother bishops are merely the authoritative, Spirit-protected guardians of revelation (i.e. the Apostolic Deposit of Faith) that has already been delivered to us, in full, by the Apostles.
Catholics clearly believe, only God can commission someone to be an Apostle.
While a Pope, or another bishop, may not succeed to the full office of an Apostle (e.g. the Apostle Peter), they do succeed to a dimension of the Apostolic office: and that is the episcopal dimension of the Apostolic office. In other words, all Apostles, as part of their Apostolic calling, were also bishops (e.g. “overseers” – pastors of the flock). Peter calls himself a “presbyter” among other (non-Apostle) presbyters in 1 Peter 5:1, as does the Apostle John in 2 John 1 and 3 John 1. Here, it is important to note that, at the time the New Testament was written, the terms “bishop” (“overseer”) and “presbyter” (“senior” / “elder” – which would eventually evolve into our English word “priest”) were still being used interchangeably (and this is more than understandable, given that all Catholic bishops are also priests).
And so, when the Bishop of Rome says that he is the successor of the Apostle Peter, or when the Bishop of Ephesus says that he is the successor of the Apostle John, they are referring to the episcopal offices held by Peter (1 Peter 5:1) and by John (2 John 1), and not to the full measure of their Apostolic ministries.
Only God can appoint an Apostle. Such was clearly the case with the Apostle Paul, who did not succeed from any of the Twelve (the Twelve were made Apostles to the Jewish people, by the way), but was called directly by Christ Himself to be an Apostle to the Gentiles. So, it is certainly true that no human authority made St. Paul an Apostle. However,
if you read Acts 13:1-3, you will clearly see that a human authority (i.e., the bishops of the church of Antioch) DID appoint both Paul and Barnabas, by the laying on of hands, to their episcopal offices (thereby giving them the authority to found other churches and to ordain other presbyters within them: Acts 14:23). Before this time, neither Paul nor Barnabas ordained anyone, nor did they claim the authority to found any churches (but merely, in Paul’s case, to preach the Good News, which is the function of an Apostle). Yet, only a bishop can ordain or establish churches; and a bishop is also subject to Church hierarchy and submits to it when necessary (e.g. Acts 15:2).
