[quote=larry j]Lets use personal understandings for a bit before we start quoting the catechism.
Is Lust really a mortal sin or were they just kidding???
When we make the other gender an object for our sexual pleasure arre we sinning??? Is pornography the same thing i.e a sin??
Lust is an often misused word in our society. Most people think it is now a good thing to say they still feel lust toward their spouse or whatever, meaning they still have instense feelings of sexual desire. But “lust” the word is not meant to be used that way. It is supposed to mean the disorderment of desire, wanting someone or something in a wrong way.
Lust really is a mortal sin. To lust after someone whether they know it or not is a sin. As for whether they share in that sin, it depends. A person can be the object of lust even if they are themselves perfectly modest and thus there is no sin on their part.
However, if you mean more popularly someone like Britney Spears, who dresses provocatively (immodestly), then yes, she would be guilty of sin merely by encouraging others to be lustful looking at her. It doesn’t matter if she says, I don’t dress this way to please others just myself or anything like that.
Immodest dress can lead to other sins too. Last summer I found myself quite angry at some of the teens who came to Mass dressed improperly. Thank goodness I wasn’t afflicted with lust but I was very distracted and condemning of them in my own head. I spent most of the rest of Mass with my eyes closed asking Jesus to help me stop focussing on other people’s sins and bring my focus to Him.
