Moral theology is a branch of theology, the science of God and divine things. It is also considered the study of "the beginning and end of a man's moral life" and essentially the analysis of how one should act. As a Roman Catholic, life is marked by inner devotion to God and observance of the Ten Commandments. By theology we mean supernatural theology which is the science of God and divine things, to the extent that it is based on supernatural revelation. The central theme contains not only God in his essence, but also his actions, and his works of salvation and guidance, which are led to God who will be our supernatural end.

The teachings of Leo XIII also constituted an essential contribution to the developments of modern social and economic life. He anchored his social ethics in the supreme value of the human person and added that all political and social structures must respect and respond to this primary and moral claim to human dignity. If the Church and the political community are autonomous and independent of each other in their own domains, the Church is “both the sign and the safeguard of the transcendental dimension of the human person ».”.
