Will Catholics ever get over this desire to parse all sins into being either “venial” or “mortal?”
Huh?
It is simply the truth and a very important truth.
It is quote important to know what is mortal sin and what is venial sin.
All sin is sin, though in differing degrees.
No actually not. Difference in kind. In reality.
There is an abyss that separates mortal sin and venial sin.
Like saying death from cancer is the same as a cut on the finger or a bad cold.
What you have listed above are sins of grave matter but the blanket term of “mortal” neither makes sense nor helps to understand the subject.
Yes grave matter.
And yes objectively mortal sin.
As I noted above the OP was not asking about culpability but about the nature of the sin.
And that is its nature.
And the other examples too.
This is the teaching of the Church and Catholic Moral Theology.
If we start mixing in the question of culpability - which is not what the OP asked - then that changes the question.
In this case, the Church considers all sins involving the misuse of the sexual act as being sins of grave matter. Depending upon the culpability of the person involved, however, the Church maintains that certain considerations of psychology or physiology can either diminish or reduce the the gravity of the act for the individual. In that case, then, masturbation was not a “mortal” sin. The blanket statement doesn’t work. In any event, it has aways been the Church’s position that it is unrepentant mortal sin that puts one’s soul at risk.
A single mortal sin that is *committed *(meaning here with full knowledge and deliberate consent)- already puts his soul at risk until it has been repented with the grace of perfect contrition (intending to confess ASAP) or been confessed and absolved.
That again is getting into not the question the OP asked. He asked about the sin itself. And it is a mortal sin.
As to culpability - the “committing” of mortal sin - yes more is involved then the nature of the sin itself.
Again there is a difference between the nature of the sin itself and the very different question of the culpability of the person involved.
Masturbation is itself a mortal sin. As is adultery etc.
A person who willfully commits murder and adultery has more to worry about than whether what they did was “mortal” or not; their actions are outward signs of their rejection of God which is not something most people who fall into masturbation intend.
As to the first part - yes that has to do with a “committed” mortals sin.
As to the second part - that is not entirely correct. One does not need to intend their actions to be signs of rejection of God in order to commit a mortal sin. Mortal sin is committed when for whatever reason a person chooses the grave matter with full knowledge and deliberate consent. They do not have to intend in any way to reject God (see* Veritatis Splendor* by Pope St. John Paul II).
