1776. What is the object chosen of a moral act? (CCC 1751) The object chosen of a moral act is the finis operis (Latin: end/ aim of the act): the end resulting from the nature of an act.
E.g. specific human acts can result in: giving alms, reading, building, singing, murdering (etc.).
1777. What is the intention of a moral act? (CCC 1752) The intention of a moral act is the finis operantis (Latin: end/ aim of the acting subject): the interior reason why the acting subject is performing a certain moral act.
E.g. one can give alms to be seen by people, to help one’s neighbour and/ or to express one’s love for God (etc.).
1778. Why can a good intention not make evil behaviour good or just? (CCC 1753) A good intention cannot make evil behaviour good or just, because the end does not justify the means.
1779. What are the circumstances of a moral act? (CCC 1754) The circumstances of a moral act are elements that “stand around” the action and increase or diminish its moral goodness or evil without changing the moral quality of acts themselves.
E.g. the amount stolen, the kind of people helped, the degree of danger overcome (etc.).

1781. Why can the object chosen by itself vitiate an act in its entirety? (CCC 1755-1756) The object chosen can by itself vitiate an act in its entirety, because there are acts which, in and of themselves, independently of circumstances and intentions, are always gravely illicit by reason of their object (= finis operis).
E.g.: fornication, blasphemy, perjury, murder, adultery (etc.).
