Free to leave, free to stay. Liberty of movement is a right most of us take for granted. Have you resided in more than one place? On this 109th World Day of Migrants and Refugees, Pope Francis asks us to imagine a world in which everyone has the option to stay or go as they please. It necessitates a world in which staying is safe: free from discrimination, violence, and dire poverty. All would have the protection of equal rights and respect, and could reach their potential in their present circumstances. Until that day, welcoming the stranger is our sacred obligation.
