[PetroniusMaximus]

"Does it never cease to irk you that the Catholic Church IS the Church of the apostles?"

The RCC is the "Church of the Apostles" only in the sense that, like the early disciples, it is continually striving with others over the answer to the question, "Who is the greatest in the kingdom of heaven?"

Luke 22:24
"And there was also a strife among them, which of them should be accounted the greatest."

[Salvation]

And in the Acts of the Apostles, Christ gives the keys of the kingdom to Peter!
