In “Pope Francis Suggests Donald Trump Is ‘Not Christian’” we learn that a man riding the “papal airliner” (perhaps a Boeing 777; source) back to his walled immigrant-free sovereign territory equates “Christian” with “welcoming immigrants.”
This raises the question of which religion can claim the high ground when it comes to welcoming migrants. Arabs are legendary for hospitality, but perhaps that tradition predates Islam? And how can we explain the fact that few migrants have been welcomed by Arab countries? (During an early 1990s visit to Egypt I learned that an immigrant family can expect to wait a minimum of 125 years before any member is granted Egyptian citizenship.)
What about Buddhism? Hinduism? Other religions with a lot of adherents?
Finally, when can we expect the papal airliner to land in Kabul to pick up a full load of Afghanis so that they can begin their new life within the Vatican? (Wikipedia says that 550 can be welcomed on each flight.)
