May one disregard a morally certain conscience on a particular matter w/o sinning?
If I am convicted in my conscience that "X" is a sin - even though it is no actual sin at all.
But I do "X" anyway - is it a sin?
Here's Matthew's explanation, again....
Do you know what moral certainty even is? It means you have enough certainty to ACT upon. Human actions are moral actions (right or wrong). There are no "neutral" actions. Either an action is good (to various degrees) or bad (to various degrees). Wiping sweat off my brow would probably qualify as "good", albeit a very very slight good.
Moral certainty is not to be confused with metaphysical certainty, or dogmatic certainty.If a man leers at my daughter, I can be "morally certain" he's up to no good and would take action accordingly (not let him close to my family, etc.) and I would do well in this.
But it's theoretically possible he had a mental or physical disorder which made him APPEAR to be leering at my daughter, when he actually wasn't.
But no matter, I had moral certainty -- enough to act upon.
You can become convinced of whatever position you want -- but guess what? You can't judge other Catholics who disagree with you, as if you are "right" and they are "wrong". You can argue, sure, because only one of you can be objectively right. But unless you've been receiving visions and revelations from Heaven, I have just as much chance of being right as you.
In short, you can't condemn, look down on, or disparage fellow Catholics who disagree with you on your opinions. You have no dogmatic certainty -- only enough for YOU PERSONALLY to act on, for you and your family. That is NOT enough to compel the consciences of others, or condemn others about.
