Ex cathedral and infallibility are meaningless if there is no Vicar of Christ. The pivotal scripture is Mt. 16:18. Jesus either makes Peter pope or He does not. The papacy stands or falls here. If Peter is pope, anyone outside the Holy See is apostate, They are usurping authority. Rome gives authority to no one outside her jurisdiction. See Council of Trent. If Peter is not Vicar of Christ, Rome is apostate and without authority--a usurper. This would include her daughters. They could take no authority from her--she has none to take. This notion would get you burned at the stake 500 years ago. Millions have died refusing to bow to the authority of Rome. We are still out here.
Even so, come, Lord Jesus.

That is not the only verse, James.
John 21
15So when they had finished breakfast, Jesus said to Simon Peter, “Simon, son of John, do you love Me more than these?” He said to Him, “Yes, Lord; You know that I love You.” He said to him, “Tend My lambs.”16He said to him again a second time, “Simon, son of John, do you love Me?” He said to Him, “Yes, Lord; You know that I love You.” He said to him, “Shepherd My sheep.” 17He said to him the third time, “Simon, sonof John, do you love Me?” Peter was grieved because He said to him the third time, “Do you love Me?” And he said to Him, “Lord, You know all things; You know that I love You.” Jesus said to him, “Tend My sheep.
It doesn't matter if you don't give it a title. Jesus Christ took him to the side, spoke to him personally, and said to shepherd his sheep.
Now if you want to challenge Jesus decree, do so here. Tell Jesus he is wrong Peter does not shepherd Christ's sheep
