What are Mortal Sins In the Catholic Church & Where Can I Find a Mortal Sin List?

mortal sin

It’s not easy to find a mortal sin list.

We do know that some of the most frequently confessed sins are sins against purity.

Most practicing Catholics know when they’ve committed such sins and also know to go to confession.

However, it can be hard to discern if some sins are grave enough to be considered mortal sins.

So, is there a list of mortal sins somewhere?

I found this nice list of grave sins, which can be mortal sins, depending on the circumstances.

Wait, is any list of mortal sins “nice”?

If you have a better list of grave/mortal sins, please share.


Grave/Mortal Sins List

    The list of mortal sins evidently are many. The one area I believe is not preached today by priests. The fact that the Holy Eucharist must not be received if the the person is not in the state of grace.
    The lines to receive Communion are long. The lines for reconciliation are short. I am 83 years old.
    It seems that Archdioceses are more concerned in how any parishioners receive the Holy Eucharist
    than go to confession. That has become the forgotten Sacrament.

      It does seem that way. I have an opinion that under the list of mortal sins, which could all be summed up as 4 ( idolatry, murder, lust, & stealing) when fornication is listed in red lettering it usually means a definition. This one goes straight to an add of Coventry ? If I understood it correctly. Now don’t you think that this is a form of theft?

      Update: the add was for Coventry eyes & my computer said the site was not safe!

        Well your computer is wrong. 🙂

        It’s obviously an ad. Ads are not bad. Ads are how lots of people find out about things. If you are struggling with pornography, you might find an ad like this interesting. Covenant eyes does some great work with offering filtering software for those who struggle with online pornography.

        Websites contain ads, because it is one way users can help to support sites that they like. Sites have expenses. No one is forced to buy anything through an ad and no one is forced to click on an ad.

        Have a blessed day!
