So this question on healthcare and social justice has had me thinking all day, so I pulled my out my Sources of Catholic Dogmas book. It appears to me that two encyclicals may help me to further understand and contemplate these topics, and thus, will be of great value to me.
Rerum Novarum by Pope Leo XIII (1891) and Quadragessimo Anno by Pope Pius XI (1931). If anyone is interested in reading along and discussing these, sound off in the comments. It may turn out to be some good Lenten reading.
