By Joseph Pearce, Catholic World Report - “We are builders of bridges, not of walls,” said Bishop Giovanni Angelo Becciu, a senior member of the Roman Curia, in January 2017. His words were a reaction to President Trump’s ordering restrictions on immigration during the present incumbent’s first term of office... The best way to respond to Bishop Becciu’s words would be to remind him of the social teaching of the Catholic Church and especially the teaching of subsidiarity. The Church’s teaching on subsidiarity, as iterated and reiterated in papal encyclicals by Leo XIII, Pius XI and John Paul II, is that matters ought to be handled at multiple appropriate levels of organization and should not be devolved to large central governments.
