In a nutshell I think Dorothy Day and Thomas Merton clearly recognized that to be a faithful member of the church, it includes and even requires being concerned with issues that go beyond the church door, it's not only possible, but also proper, for a Catholic or a member of any other religious tradition to be concerned with justice, peace in the world, understanding of other faiths and concern for the environment. [Pope Francis] is putting on record that what he’s doing is not all that new.
