All RC Priests and Bishops are chosen by laying on of hands. Y'all are getting stuck on the POPE. Don't get stuck on stupid. It's the Apostles (all of them) and their successors that are important, not just the Pope.
And Pius XII was a glorious, wonderful man, not some nazi enabler.
The Pope is supposedly the end of a long chain of "unbroken Apostolic succession" from Kefa (St. Peter). The only sort of succession we find in Scripture is either by birth (i.e., the monarchy or high priesthood) or laying on of hands by the predecessor. The only exception to this is the replacement of Judas, for the obvious reasons, in which case the other Apostles still laid hands on Mattiyahu (Matthias) to confirm him.
It's irrelevant in any case. An apostate cannot confer authority by laying hands on anyone, nor does having hands laid prevent one from becoming an apostate. Ultimately, it is not those who are supposedly the successors of a person (as the Pharisees claimed they were the successors of an unbroken chain of hand-laying going back to Moses) nor those who say, "Lord, Lord" who are God's true Church, but those who do what He tells them to (Mat. 7:21ff).
Like the Pharisees and moreso, the RCC's priests flagrantly disregards Scripture where it is in conflict with their traditions. Ergo, they do not have the authority to lay hands and elect a "pope" over the true, Spiritual Church.
