VATICAN CITY — Pope Francis issued the mission statement for his papacy Tuesday, outlining how the Catholic Church and the papacy itself must be reformed to create a more missionary and merciful church that gets its hands dirty as it seeks out the poor and oppressed.

In the 85-page document, Francis pulled together the priorities he has laid out in eight months of homilies, speeches and interviews and put them in the broader context of how to reinvigorate the church’s evangelical zeal in a world marked by indifference, secularization and vast income inequalities.
