I did a thread on this a while ago but it didn’t achieve my objective.
I am from a background that takes the position that, basically, anything you do is a mortal sin. You can’t breathe or exist without doing something that would cut off your relationship with God - that we, by nature, deliberately cut off our relationship with God. Hence the need for overpowering grace that subsumes all human faults: cooperation is irrelevant, so faulted is man, etc. Enough on that.
In contrast I just read a thread on which it seemed people are taking the position it is almost impossible to commit a mortal sin. According to this viewpoint you have to go way out of your way with full deliberation to do it. Since we love Jesus, we would never do such a thing with full consent. We would have to be crazy to sin mortally, meaning that we have an insanity defense, so it is not mortal sin.
So I look at this, and think: maybe I have no mortal sin? Maybe it is so hard to do that all I have done is venial, regardless of how heinious it was, because some part of me, at least, wanted to please Jesus at the same moment I was sticking my thumb in His eye by what I was doing.
I have no baseline for determining frequency. This poll is private. I would appreciate it if Catholics would say how often they identify something as a mortal sin in their lives. Really nosy of me, I will agree. And no, I want no details or stories of how you set fire to Uncle Fritz or whatever.
