My short introduction and paragraph-by-paragraph summary of Pope Pius XI’s social encyclical Quadragesimo Anno, will help answer that question. The second in a series on the social documents that make up the “canon” of the social teaching, this little book is ideal for students of the document and of social teaching in general. It is currently available in eBook and paperback. Audio version coming eventually.
This is currently available on Amazon, but you can encourage your local Catholic bookstore to order their own copies.
