Is this mortal sin if you stop believing?

[Billy3]

Hi, so… if one is Catholic and knows that some action is a mortal sin, but then stops believing in the church, and commits the action which is a mortal sin, but no longer thinking it is (for that matter that there is no such thing) a mortal sin.
Then couple days later beleives in mortal sin and the church again, would the said action be considered mortal or not?

Got this from Wikipedia In Roman Catholic moral theology, a mortal sin requires that all of the following conditions are met: Its subject matter must be grave . It must be committed with full knowledge (and awareness) of the sinful action and the gravity of the offense. It must be committed with deliberate and complete consent.

See @Rosie11 response above.

I’d like to add, however. That is for someone who is completely ignorant of God’s righteous commandments. Catholics aren’t. Of course, God alone judges the heart, but, those who willfully reject the Teachings of the Catholic Church fall under another standard. Incredulity.

2089 Incredulity is the neglect of revealed truth or the willful refusal to assent to it. "…

Incredulity is, itself, a mortal sin. It means that the truth has been presented to you and you refuse to believe it.

This person would be well advised to go speak to their priest in the confessional. I would advise making an appointment early this week, Holy Week is packed.

Rejoining the Church is not the same as forgetting that something is considered a mortal sin by the Catholic Church.

In order for the person in question to be free of committing a mortal sin they would have to be completely ignorant, meaning never having heard or learned that such action was a mortal sin, not never having believed in this definition. There is a difference between learning of this and believing in this.

Unless the subject can erase all knowledge of Catholicism (such as with a case of amnesia–which would have to be quite selective in this instance), merely leaving the Church would not make them ignorant of what the Church taught on matters of mortal sin. Joining the Church a “couple days later” would still make the person guilty of mortal sin in this scenario.

So on Monday you are a Christian but when you wake up on Tuesday you are an atheist. You’re still an atheist on Wednesday but on Thursday it’s back to Christianity.

Can’t wait for the weekend to see what happens next.
