The tenure of Pope Francis has been marked by his support for a host of causes more closely associated with the political left, including climate change, greater regulation of capitalism, and the fate of refugees attempting to reach Europe. He's even taken modest steps on more explicit doctrinal issues such as opening certain church leadership roles to women, emphasizing the importance of welcoming LGBTQ individuals into the church (while still, of course, condemning homosexuality), greater flexibility with regard to divorce, and the possibility of relaxing the priesthood's celibacy requirement. Particularly when set against the rising forces of reactionary nationalism in the late 2010s, Francis's service as the Bishop of Rome has seen a marked shift away from the fiercely anti-communist rhetoric of Pope Benedict XVI and Pope John Paul II.
