Still, as Blessed John Henry Newman pointed out, the political power of the pontiffs is something that is not essential to the Petrine mission. One day, Peter, like Christ, may have no place to rest his head.
The Vatican is not the Church and is therefore not the Bride of Christ
Bl. John Henry Newman was theologically correct, which is how he is to be understood. We know this from Tradition. Just look at the number of popes executed, exiled and imprisoned through the centuries, yet the Petrine Ministry continues.
However, it is precisely this history that also serves to help us understand the benefit of a sovereign state from which the Petrine Ministry can be exercised without persecution. To protect the Petrine Ministry, we protect the sovereignty of the state that is the home to the ministry.
There are many things in the Church that are not essential, but beneficial. The priesthood is not essential to consecrated life. Yet, how many consecrated religious are also priests?
Some things exist because they are a good, not necessarily because they add to the essence of something else.
The analogy of the Son of Man not having a place to lay his head does not include Peter. Jesus makes this statement before his passion and resurrection. Jesus transfers the pastoral care of the Church to Peter after the resurrection. Therefore, Peter becomes the Vicar of a triumphant Christ, not the suffering servant prophesied by Isaiah. It is the glorified Christ, who has triumphed over death and sin, who confirms Peter’s pontificate and who asks Peter to care for his sheep.
The reference that Christ is making when he says that the “Son of Man has no place to lay his head” foreshadows how he was to die. It is a reference to the Suffering Servant in Isaiah. Peter is not the Suffering Servant. He is the Vicar of the risen Christ.
Jesus did foreshadow the Peter would suffer. As we have seen through history. Peter has suffered and will continue to suffer.
That being said, Peter is not the Church. Where there is Peter, there is the Church. The Church is our mother. She has a right to have a home and the duty of Catholics is to protect that home, just as we would protect the home of our biological mothers if it were under attack even if it were just a bunch of rowdy kids throwing eggs at Mom’s house. We wouldn’t stand by and watch.
