70. The Church has the right to be a teacher for mankind, a teacher of the truth of faith: the truth not only of dogmas but also of the morals whose source lies in human nature itself and in the Gospel. The word of the Gospel, in fact, is not only to be heard but is also to be observed and put into practice (cf. Mt 7:24; Lk 6:46-47; Jn 14:21,23-24; Jas 1:22). Consistency in behaviour shows what one truly believes and is not limited only to things strictly church-related or spiritual but involves men and women in the entirety of their life experience and in the context of all their responsibilities. However worldly these responsibilities may be, their subject remains man, that is, the human being whom God calls, by means of the Church, to participate in his gift of salvation.

197. Besides the principles that must guide the building of a society worthy of man, the Church's social doctrine also indicates fundamental values. The relationship between principles and values is undoubtedly one of reciprocity, in that social values are an expression of appreciation to be attributed to those specific aspects of moral good that these principles foster, serving as points of reference for the proper structuring and ordered leading of life in society. These values require, therefore, both the practice of the fundamental principles of social life and the personal exercise of virtue, hence of those moral attitudes that correspond to these very values.
390. The profound meaning of civil and political life does not arise immediately from the list of personal rights and duties. Life in society takes on all its significance when it is based on civil friendship and on fraternity. The sphere of rights, in fact, is that of safeguarded interests, external respect, the protection of material goods and their distribution according to established rules. The sphere of friendship, on the other hand, is that selflessness, detachment from material goods, giving freely and inner acceptance of the needs of others. Civil friendship  understood in this way is the most genuine actualization of the principle of fraternity, which is inseparable from that of freedom and equality. In large part, this principle has not been put into practice in the concrete circumstances of modern political society, above all because of the influence of individualistic and collectivistic ideologies.
