Lazerlike42:
… there is a major misunderstanding that the gravity is what makes a sin mortal or venial …
The gravity of sin is an objective matter, not a subjective matter. The Catholic Church teaches that some sins are by their nature more grave than others.
God determines the degree of culpability that one has when one commits a sin involving grave matter. Ignorance of Church teaching may lessen or even eliminate the imputability of a grave offence against God. **Catechism of the Catholic Church
1792** Ignorance of Christ and his Gospel, bad example given by others, enslavement to one’s passions, assertion of a mistaken notion of autonomy of conscience, rejection of the Church’s authority and her teaching, lack of conversion and of charity: these can be at the source of errors of judgment in moral conduct.
1793 If - on the contrary - the ignorance is
invincible, or the moral subject is not responsible for his erroneous judgment, the evil committed by the person cannot be imputed to him. It remains no less an evil, a privation, a disorder. One must therefore work to correct the errors of moral conscience.
1859 Mortal sin requires full knowledge and complete consent. It presupposes knowledge of the sinful character of the act, of its opposition to God’s law. It also implies a consent sufficiently deliberate to be a personal choice. Feigned ignorance and hardness of heart do not diminish, but rather increase, the voluntary character of a sin.
1860 *Unintentional ignorance * can diminish or even remove the imputability of a grave offense. But no one is deemed to be ignorant of the principles of the moral law, which are written in the conscience of every man. The promptings of feelings and passions can also diminish the voluntary and free character of the offense, as can external pressures or pathological disorders. Sin committed through malice, by deliberate choice of evil, is the gravest.
I was clearing up the misunderstanding that a sin is mortal or venial in its nature (which is untrue) as opposed to the correct understanding that a sin is mortal or venial not because of itself but because of the state of the person’s heart whom commits it (i.e., their turning of their back upon God deliberately with knowledge etc.)
A child that has reached the age of reason that deliberately sasses his mom is breaking the Fourth Commandment. Does God see this deliberate act of disobedience against one of theTen Commandments as a mortal sin that would condemn the child to eternal damnation?
There are sins that do not involve grave matter, and committing these sins with deliberate intention does not destroy the abiding of God within the soul - these deliberate venial sins do, however, spiritually wound us, but they are wounds that are not mortal wounds.
