I’m having a bit of trouble with mortal sin. I understand the scriptural and traditional basis for mortal sin. I also understand the three conditions for mortal sin. My question is what constitutes a “grave” issue or matter?
I had people tell me that eating meat on Fridays was a “grave” issue. I am finding difficulty in ascertaining what is “grave” and what isn’t. The Church doesn’t provide some canonical list of all the grave issues. I want to know what I need to mention at confession (grave issues, therefore mortal sins), and what I can confess personally through prayer and mass (non-grave isues, therefore venial sins).
So how do we find out what is considered grave? What documents do we use as the basis for this? The Ten Commandments? Canon law? Civic law? Gut feeling? Finally, when an issue is in dispute, who has the final authority to “declare” it as grave and thus impose mortal sin?
I know it’s a mouthful of questions, but I really appreciate the insight and charity here on this forum! Thanks a lot!
P.S.- If eating meat on Fridays is actually a grave issue, could someone please explain how it is? Thanks again!
