Modern Catholic social teaching is the body of social principles and moral teaching that is articulated in the papal, conciliar, and other official documents issued since the late nineteenth century dealing with the economic,political, and social order. This teaching is rooted in the Hebrew and Christian Scriptures as well as in traditional philosophical and theological teachings of the Church.

CLINIC's "Modern Catholic Social Teaching on Immigration: Notable Quotes" is a compilation of excerpts from the encyclical and conciliar documents that are typically considered core texts, as well as some key teaching documents issued by national bishops conferences and Vatican congregations, which contribute to the ongoing development of Catholic social teaching.

The excerpts in the document are instances that touch on immigration issues. The depth and richness of Catholic social teaching is best understood through a direct reading of these documents.
