well excuse me
since OP says he is not sure what his source is refering to as “types of sin” we are all offering guesses. my suggestion is go back to your source and ask them what they are talking about and ask for an authorotative citation.
Perhaps I can shed some light on this,since I am the OP she is talking about here. First of all, I never stated that there are 3 types of sin. We learned from the first grade and the old Baltimore Catechism that there are two. The entire discussion began when I stated that I felt that all practicing Catholics should partake in the Sacrament of Confession at least once a year. I was immediately jumped on, by those stating that this was not true, unless you had committed a mortal sin. I produced the precept concerning this from my sources and they produced the precept proving their point with their sources. This is the one I produced:
2042 …
The second precept (“You shall confess your sins at least once a year.”) ensures preparation for the Eucharist by the reception of the sacrament of reconciliation, which continues Baptism’s work of conversion and forgiveness.
My source did not contain a modifier for sin. I merely stated that when I examine my conscience, I determine,
for myself, what I have done and what I have failed to do, I used the example of stealing a dime from a poor woman compared to stealing a dime from a billionaire. I considered the former to be a grave sin. And all of a sudden, in their eyes, I made up a new category of sin.
Further, we read this in the Catechism:
1854 Sins are rightly evaluated according to their gravity.
There is no modifier there, either. I read this to say that ALL sins are evaluated as to their gravity.
That was my contention; nothing more.
