Throughout his public life, Pope Francis has been noted for his humility, emphasis on God’s mercy, international visibility as pope, concern for the poor and commitment to interfaith dialogue. He is credited with having a less formal approach to the papacy than his predecessors, for instance choosing to reside in the Domus Sanctae Marthae guesthouse rather than in the papal apartments of the Apostolic Palace used by previous popes. He maintains that the Church should be more open and welcoming. He does not support unbridled capitalism, Marxism, or Marxist versions of liberation theology. Francis maintains the traditional views of the Church regarding abortion, marriage, ordination of women, and clerical celibacy. He opposes consumerism and overdevelopment, and supports taking action on climate change, a focus of his papacy with the promulgation of Laudato si’. In international diplomacy, he helped to temporarily restore full diplomatic relations between the United States and Cuba and supported the cause of refugees during the European and Central American migrant crises. Since 2018, he has been a vocal opponent of neo-nationalism. Francis has faced increasingly open criticism, particularly from theological conservatives, on many questions, including the admission of civilly divorced and remarried Catholics to Communion with the publication of Amoris laetitia and on the question of the alleged cover-up of clergy sexual abuse, against which he promulgated Vos estis lux mundi.
