Please! Do you really buy what you just wrote? How does that remotely support your contention that you don’t have “duties” to the pope? No real Catholic would nor could believe such a thing. I suggest you rethink this blatantly unorthodox position.
It depends how you define duties.
Are catholics required to pilgrimage to rome and pay homage to the pope, like the muslims at mecca? No.
Are we required to do anything to him on a personal level? Send Christmas cards? Have a photo of him in our house? Know his middle name and family history? No, no and no.
I suppose the only "duty" I could come up with is to pray for the pope...but that's not really a duty, but part of the Faith. It's part of many novenas, and the mass.
Could a catholic grow up in some poor country, and live his life only going to the dirt-floor church down the road, never leaving his tiny little village, without ever knowing the pope's title or anything about him? Yes.
So, if such a person could save their soul, what "duty" did they fulfill?
