As in, Paul personally sponsored Timothy as a Bishop, and Apollos also. And he did that without asking Peter or James, because he even said that he's sending a certain church Timothy to be Bishop.
So since Paul didnt ask James or Peter, isn't that proof that Bishops today don't have to go through a Pope to ordain other Bishops and send them to a Church? Well, the Book of Timothy talks about how to be a Bishop, that's why Timothy was a Bishop. :)
