If you don’t have a copy of the Catechism, there is another section that is relevant to your question here.
ccc 1735 Imputability and responsibility for an action can be diminished or even nullified by ignorance, inadvertence, duress, fear, habit, inordinate attachments, and other psychological or social factors.**
This is a really vague and general statement that refers to whether you have complete freedom in a situation. So, something like fornication (having relations with a girlfriend) may be objectively a mortal sin, but a person committing it may have diminished responsibility for it.
I’ve sought guidance on this paragraph of the Catechism, what does it mean. the answers are mostly like those preceding this post, it’s wrong, it’s wrong, it’s wrong. I believe that this paragraph is not as legal sounding as it may be, rather , it’s about God’s mercy. There are circumstances, perhaps many of them, which diminish a person’s responsibility for some action. But, I have found no definitive explanation of it.
And this paragraph does not even list all the reasons for which our responsibility might be diminished. 1735 is based on the teaching of the Bible. For example, on the cross, Jesus prays, Father forgive them, for they know not what they do. <-- ignorance. These people think they know what they’re doing, but they really don’t, and Christ prays for their forgiveness.
In the Old Testament, there’s an example of a slave woman who is forced into a sexual encounter against her will – she is not guilty of it.
It isn’t right for me to delve further into your personal matter that you described. But, as Fr. John Riccardo, radio priest in the Archdiocese of Detroit says, God is not waiting up there to drop an anvil on our heads, if we make a mistake. Others have made more pointed remarks above.
We should, though, have a profound respect for God’s commandments. It’s not enough to know them, we have to live them. And, we have to know that there are consequences to our sins, not just in eternity, but here and now. Having unmarried sexual relations can have a lot of consequences, including leading us further into sin.
Scripture, essentially, teaches us to control our passions. We should learn this lesson.
