Editor's note

Over the weekend, protests broke out at airports and cities across the country against President Trump’s executive order banning the entry of citizens of seven majority-Muslim countries. While critics are using legal and moral arguments to try and overturn the order, two scholars of  immigration policy say U.S. history shows that excluding immigrants based on nationality is bad foreign policy and “risks straining or losing important diplomatic ties and fragile relationships.”

So what does the Bible say about what it means to welcome strangers? Religion professor Matthew Schmalz argues that both the Old and New Testaments are unambiguous: they must be treated with dignity and hospitality.

    Yoshitaka Ota, University of British Columbia; Andrés Cisneros-Montemayor, University of British Columbia

    Coastal indigenous peoples consume nearly four times more seafood per capita than the world average and have strong cultural ties to the sea. Global ocean policies should preserve these connections.
