Aren't you trying to bring schism to the Church?
Certainly not - I propose that the legitimate Papacy reassert its claim on the city of Avignon and that the Papcy take up residence there are a nice change of scene.
Didn't St Catherine of Siena argue against an Avignon-based papacy?
Certainly, but her Dominican confere St Vincent Ferrer was supportive of Benedict XIII's Avignon Papacy.
But shouldn't the Papacy be in Rome?
Many Popes have, for various reasons, chosen to live outside of Rome. Avignon is probably the most famous, but at various times the Papacy has been based in other cities. The Pope is always Bishop of Rome, but history provides ample examples of him chosing to live elsewhere.
