This chapter explores traditions within U.S. Catholicism that exemplify working alternatives proposed by Pope Francis in his 2015 encyclical, Laudato Si’. The first part of the chapter presents resources that emerge within Dorothy Day’s and Peter Maurin’s Catholic Worker newspaper, with special attention to the perspectives of John Hugo and Paul Hanly Furfey on Catholic farming communes in the 1940s and Thomas Merton’s view on the emerging U.S. ecological movement in the 1960s. The second part of the chapter examines the ways in which contemporary communities of religious women and their lay collaborators pursue ecological justice in the early twenty-first century. Taken together, a long-standing tradition of Catholic working alternatives emerges that emphasizes the combination of prayer and work thus presenting a significant alternative to a cultural and political-economic system that denigrates human dignity and imperils natural ecology by rupturing the divine-human relationship.
