VATICAN CITY (CNS) — Christians have a moral obligation to show God’s care for all those who are marginalized, especially migrants and refugees, Pope Francis said. “This loving care for the less privileged is presented as a characteristic trait of the God of Israel and is likewise required, as a moral duty, of all those who would belong to his people,” the pope said in his homily Sept. 29 during an outdoor Mass for the 105th World Day of Migrants and Refugees.
