Please recall that you’re the one who is citing the Bible as your source for Peter being the first Pope, not me.
I generalized the quote, I did not cite verbatim....
I am not Catholic so I have no horse in this race. However, there were no other formal Christian religions or “organizations” for those that like that word that were in existence. All the other Christian religions spawned off of Catholicism.
Regardless of whether or not Christians believe in the authenticity of the Catholic Church, all Christians should be respectful since it was the Catholic Church that saved “scriptures”, it was the Catholic Church that prevented the spread of Islam over Christianity, and it would be a very different world today if the Catholic Church were not in existence.
