The Catholic Churc is dying and is looking to Hispanic migrants in America to fill the pews, so THAT is the Pope’s self interest regarding illegal peasant migration.
We can help by removing all social services for anyone who has two illegal status parents.
The USA has the most Christian (as in ethical) immigration policy on earth. Anything above that and the legal immigrant quota is illegal and anyone advocating for those illegals is guilty of the sin of greed and envy.
Follow the money. Catholic charities are given large amounts of money by the USG to resettle immigrants and refugees.
