CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 1887–1891

1887 The inversion of means and ends, which results in giving the value of ultimate end to what is only a means for attaining it, or in viewing persons as mere means to that end, engenders unjust structures which "make Christian conduct in keeping with the commandments of the divine Law-giver difficult and almost impossible."
1888 It is necessary, then, to appeal to the spiritual and moral capacities of the human person and to the permanent need for his inner conversion, so as to obtain social changes that will really serve him. The acknowledged priority of the conversion of heart in no way eliminates but on the contrary imposes the obligation of bringing the appropriate remedies to institutions and living conditions when they are an inducement to sin, so that they conform to the norms of justice and advance the good rather than hinder it.
1889 Without the help of grace, men would not know how "to discern the often narrow path between the cowardice which gives in to evil, and the violence which under the illusion of fighting evil only makes it worse." This is the path of charity, that is, of the love of God and of neighbor. Charity is the greatest social commandment. It respects others and their rights. It requires the practice of justice, and it alone makes us capable of it. Charity inspires a life of self-giving: "Whoever seeks to gain his life will lose it, but whoever loses his life will preserve it."
1890 There is a certain resemblance between the unity of the divine persons and the fraternity that men ought to establish among themselves.
1891 The human person needs life in society in order to develop in accordance with his nature. Certain societies, such as the family and the state, correspond more directly to the nature of man.
