CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 1747–1751

1747 The right to the exercise of freedom, especially in religious and moral matters, is an inalienable requirement of the dignity of man. But the exercise of freedom does not entail the putative right to say or do anything.
1748 "For freedom Christ has set us free" (Gal 5:1).
1749 Freedom makes man a moral subject. When he acts deliberately, man is, so to speak, the father of his acts. Human acts, that is, acts that are freely chosen in consequence of a judgment of conscience, can be morally evaluated. They are either good or evil.
1750 The morality of human acts depends on:

- the object chosen;

- the end in view or the intention;

- the circumstances of the action.

The object, the intention, and the circumstances make up the "sources," or constitutive elements, of the morality of human acts.

1751 The object chosen is a good toward which the will deliberately directs itself. It is the matter of a human act. The object chosen morally specifies the act of the will, insofar as reason recognizes and judges it to be or not to be in conformity with the true good. Objective norms of morality express the rational order of good and evil, attested to by conscience.
