“Don’t get too political,” some will say. Current policy and attitude toward migrant persons is rife with ignorance and hatred. We are speaking of people:
414. One of the tasks of the Church on behalf of migrants is unquestionably prophetic critique of the attacks that they often suffer, and also the effort, together with civil society organizations, to influence the governments of countries, to achieve a migration policy that takes into account the rights of people on the move. It must also be mindful of those displaced due to violence. In countries scourged by violence, pastoral action should be undertaken to accompany the victims and take them in, and offer them training so they can live off their work. Their pastoral and theological efforts to promote universal citizenship in which there is no distinction of persons must likewise be deepened.
A world with universal citizenship. It wouldn’t negate association with a nation. Dual citizenship seems fairly frequent.
