I understand that bad language is normally a venial sin.
Does the sin change if it is in relation to a priest.
In examining my conscience about something I wanted to make sure that I did not think a derogatary thought about a priest (the particular thought I was worrying about would have been extremely sinful). I realised that I hadn’t thought anything derogatory(I’m 100% sure about this) but in my examination of conscience I used some coarse language in my head while describing the situation.
There was another situation where I had a thought that a priest was good looking, but used a coarse word in my head. Again, I am 100% sure that I didn’t think any lustful or inappropriate thoughts - I just used a coarse word to describe the situation.
I am assuming that these situations are not mortally sinful as there was no ill intention in my thoughts - rather, the use of coarse/bad language.
