I. The Sources of Morality

From The Catechism of the Catholic Church

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.
