So I know that if we as Catholics do confess doubtful sins, we need to specify that they are doubtful. In the past, I have confessed a lot of doubtful sins, and I have not usually specified them as “doubtful”. At first, i did not know it was necessary, then after that I would often forget or else I would just overestimate how certain I really was. Sometimes I’ve had issues deciding if it is doubtful or not, and then there have been times here and there when I just didn’t bother.
Does this count as lying in the confessional? I know it is no big deal if I forgot or didn’t know, but what I am worried about is the times when I just didn’t bother to say so. I have indeed had confessions where I would just say my sins and not recount any details about them, including my certainty about having committed them. is this enough to potentially invalidate a confession?
