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.

    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.
