I will receive the Sacrament of Reconciliation — that is, make my first confession — for the first time this Thursday.
Looking for guidance, I find the following in the New York City archdiocese's "Guide to a Good Confession":
"When finished examining his conscience, [the penitent] should make a mental list of all the mortal sins he committed, noting how and how many times he committed them, as far as he can remember. He can also add any venial sins he remembers."
This is not helpful.
How exactly does one confess all one's sins from birth onward?
I have some vague idea of going down the list of the Ten Commandments and highlighting anything particularly egregious.
