How can you commit a sin without knowing.
Answer is you can’t. A sin is as an example thinking or doing something that you know is wrong - we all know right from wrong. So if you say something unkind to someone , you know you shouldn’t because the other person will be hurt but still you decide to say it anyway. Whether it was out of spite/ anger/ or tit for tat is another circumstance. But the gist is you still know you shouldn’t. “All wrong doing is sin”. Some mortal some venial.
So God will punish you for sins you didn’t even know you committed?
Again, see the example I gave above. People know whether something is right or wrong - their conscience tells them. So if you’ve been uncharitable as in the example above - you’ve still done wrong - you’ve sinned. In that example, the matter is venial. To commit a mortal sin requires the thing to be serious, you have full knowledge it is seriously wrong, and you still decide ’ yep, I’m doing a,b,c’ - so there is your full consent.
God is not a bully. But he is just. If you didn’t know something was grave matter, but it was and you did it willingly, then you will not be judged the same as someone who did/does have full knowledge that the matter is grave and still willingly did it.
Isn’t the important thing just to follow your conscience?
Yes, but your conscience
is to be formed according to the teaching of the Church.
The main reason we are not perfect is because God made us that way.
This was explained in another thread which you created -
God’s fault we are sinners
And purgatory is suffering
Yes, but it is a
just suffering - no more and no less than we deserve. Think of this - a boy is playing cricket and he hits the ball and goes through his neighbours window breaking it. Whilst he didn’t intend for the ball to break his neighbours window, it still did , though his culpability is less compared to if he deliberately took aim at the window and belted the ball directly at the window. So while he sincerely apologizes to the neighbour for the damage done, don’t you think it would be only fair to the neighbour that he in some way also compensated the neighbour for the cost of replacing the window? Mowing the neighbours lawn each week for a month, say?
Well this is one aspect of purgartory. All sins wounds our soul, our relationship with God and our relationship with others.
Part of being a grown-up is accepting responsibility for our actions and the decisions we make, rather than pointing the finger of blame elsewhere as a child might.
The privelege of driving and having a license also comes with obeying the road rules. Run a red light and justice means you cope a fine for doing so.
