Centesimus Annus §54

⁵⁴ Today, the Church's social doctrine focuses especially on man as he is involved in a complex network of relationships within modern societies. The human sciences and philosophy are helpful for interpreting man's central place within society and for enabling him to understand himself better as a "social being". However, man's true identity is only fully revealed to him through faith, and it is precisely from faith that the Church's social teaching begins. While drawing upon all the contributions made by the sciences and philosophy, her social teaching is aimed at helping man on the path of salvation. The Encyclical Rerum novarum can be read as a valid contribution to socio-economic analysis at the end of the nineteenth century, but its specific value derives from the fact that it is a document of the Magisterium and is fully a part of the Church's evangelizing mission, together with many other documents of this nature. Thus the Church's social teaching is itself a valid instrument of evangelization. As such, it proclaims God and his mystery of salvation in Christ to every human being, and for that very reason reveals man to himself. In this light, and only in this light, does it concern itself with everything else: the human rights of the individual, and in particular of the "working class", the family and education, the duties of the State, the ordering of national and international society, economic life, culture, war and peace, and respect for life from the moment of conception until death.
