I said that wearing those clothes is a mortal sin. I said that if someone dies by accident, and has one mortal sin on their soul, that they will not be saved.
One of the conditions which make a sin mortal: it must be committed with full knowledge, both of the sin and of the gravity of the offense.
That simple quote has been used for over 50 years to excuse everybody from practically every sin (except Adolph Hitler of course).
bowler, I did not excuse anybody.
What you said, is simply not true, and I told you so.
Merely wearing tight jeans may not even be a grave sin.
You have been corrected by some users, now get yourself a good, traditional Catechism, study the classifications of sin, and stop spreading false ideas about sin.
It's a good idea to talk about the importance of modest clothing, but without distorting the teaching of the Church, please.
You are saying, if they don't know it's a mortal sin, it is not a mortal sin. Your point is moot, it is irrelevent. Read the saints quotes I gave you. That's the Church speaking, and they all knew what you wrote.
If they don't know it is a sin, then they will know when they are told, which is what we (parents, priests, respected elders) are going to be doing, right? End of excuse.
End of story.
