Sins of omission are the failure to do something one should have done. Sins of omission may be mortal or venial depending upon what we have failed to do. The chief reasons why people commit sin may be found in the seven capital sins. You shall not afflict any widow or orphan. The sins against the Holy Spirit are despair of one s salvation, presumption of saving oneself without merit or repentance, resisting the known truth, envy of the graces received by others, obstinacy in one s sins, and final impenitence.
Social sin arises when people copy or cooperate with one another in allowing and promoting sin.
This is often evident in what becomes socially acceptable or what is institutionalized in the social structure or laws. Some examples would be slavery, child labor, neglect of the poor or marginalized. Situation ethics teaches that there is no fixed moral code given to human beings by the Creator. It holds that individuals must make moral choices according to a particular situation that is, what is right or best in this moment for me. This is because the person s basic choice, or fundamental option is for God and the good.
