Compendium of the social doctrine of the Church

"This work shows the value of Catholic social doctrine as an instrument of evangelization, because it places the human person and society in relationship with the light of the Gospel.
(...)
In the present text we can see the importance of moral values, founded on the natural law written on every human conscience; every human conscience is hence obliged to recognize and respect this law.
(...)
We can therefore easily understand the fundamental importance of the formation of the laity, so that the holiness of their lives and the strenght of their witness will contribute to human progress. This document intends to help them in this daily mission."
From the introduction of Cardinal Angelo Sodano
