  According to God's law, or those elements of it which survive in the widely held opinions of human beings all over the world, there are certain actions which are intrinsically evil or good. Our moral duties include not only the more familiar examples, such as the obligation to refrain from voluntary homicide; Pascal also quotes with approval from Cajetan that “we are obliged by justice to give alms from our surplus, to alleviate even the common necessities of the poor … those who are rich are merely stewards of their surplus, in order to give it to whoever they select from among those who are in need” (Letters: I, 714).
