The United Nations High Commissioner on Refugees testifies that an unprecedented 89.3 million people around the world have been forced from their homes by conflict and persecution. Among them are 27.1 million refugees, 53.2 million Internally Displaced Persons and 4.6 million asylum seekers. Over half of the world’s refugees are under the age of 18. 1 out of every 88 persons in the world has been forced to flee.1 Behind the cold numbers of staggering statistics that characterise contemporary global phenomenon of migration, “lie human faces struck by tragedies of immense proportions, with loss of land and homes, family separation, physical sufferings, rape, sexual violence, psychological damage, lack of opportunities for education, uncertain future, and death itself.”2 Migration is a perennial concern for the church and theology and has been addressed in many ways but fundamentally, through the church’s teaching on unconditional hospitality, and the human rights and dignity of victims. The complex nature of modern migration calls for a greater attention to the structures of society and the role they play in the migration and refugee crisis. Hence, this thesis addresses the migration/refugee crisis through the lens of “sinful social structure.” This is necessary because conflict and poverty, the two major causes of forced migration, both have roots in local/international structures. A review of Pope’s Francis’ agenda on the migration regime, and an X-ray of the situation of Internally Displaced Persons in Nigeria provide deep content for the task of the Thesis.
