In the Ancient Near Eastern context, hospitality was a pillar upon which all morality stood. To not welcome the stranger with generosity and compassion, especially one far from home, was to be immoral. In the Christian tradition the word hospitality, philoxenia in Greek, literally translates into, “kinship love for strangers.”
Welcoming strangers and vulnerable displaced neighbors with generosity and compassion should be the least controversial thing for Christians to practice, especially when we claim to follow the Christ of Christianity. Why this is ever a debate for Christians, I don’t know. But if you are convinced, find others who are, pool resources together, connect with agencies getting it done, and welcome these neighbors to find a home with you.
